Which Chassis and Why

Being a shop that sells R/C Drift exclusively, we get a lot people asking which chassis would be the best for them. Since most of this happens in store, we have the opportunity to break it down for them while taking a few factors into account. It’s a little more difficult when we see this same question posted online due to many factors. There is a lot of great advice out there, and there is a lot of bad advice as well. It’s up to you to decide which is credible and which is not. In fact, you should be asking yourself if I am even credible.

We encounter a few different types of buyers and each come with their own unique needs. What we first tell them is, they really need to be honest with themselves. The decision they make on their first setup can greatly affect the amount they spend in the long run. I believe right from the start, the first thing that should be looked at is what type of person are you? Are you the type that is content with just good enough, or are you the type to want all the good stuff? I fall into the later and ultimately could have saved quite a bit if I made the right choice at the start. If you are the type that will have everything upgraded in the next month or two, you should consider the kits that include some hop-ups already. You will save roughly 30% off your upgrade journey.

Although choosing the right chassis seems like a life decision, keep in mind most people seem to change chassis about once a year. Some keep them longer, some have multiple chassis throughout the year, but on average it seems to cycle around the 1 year mark.

If you are new to R/C Drift, (notice I worded it R/C Drift, NOT just R/C) Most likely even your past R/C knowledge will not be enough to get you where you want to be right away. R/C Drift is a different animal than any other discipline of R/C, so it’s not easy to just start out and be the superstar of the track. The main point I always stress is:

Find out what people are running where you plan to spend most of your time drifting, and go that route. There will be a ton of help and you will spend more time drifting, and less time being frustrated. You Will Need Help.

There is plenty of time to be unique later with the ultra rare chassis, but when you are first starting out, it will benefit you to be able to share tips and setups.

When choosing your first R/C Drift chassis, you will hear a ton of advice. Some good and some really bad. Some of the common, bad ones we often come across are:

1. Any chassis can be good. Yes and No.
YES – If you REALLY know what you are doing, AND you are ok throwing a bunch of money at it.
NO – If both of those statements don’t apply to you. If you’re just starting out, this is a huge NO!

We have seen many people make their initial investment in a difficult chassis, struggle alone since there is nobody familiar with their chassis or how to set it up, and finally just disappear and blow out their full setup on Craigslist.

2. The clones are just as good, just cost less.
NO – We have yet to see a good performing clone, Period.

Just don’t. Maybe later down the line when you are well versed in turning and you know exactly what you are after, then try to tackle a project like this, but for now, focus on a good, solid foundation.

Ready To Run (RTR)
Aimed toward the person who needs an entire setup. They don’t own a remote, electronics, etc. They are also trying to start out on a budget of sub $500.

The only RTR we can recommend at this time is the MST RMX 2.0 RTR.

Things to consider:
This is intended to get you going in R/C Drift. The chassis itself is the same as the regular RMX 2.0, with only a couple small differences that can be changed to be the same for a $50-$100.

It comes pre-built and tested from the factory. This means you don’t need to worry about all the small details of setting it up correctly. you just pull it out of the box and you are good to go. The tires even have a little wear on them from the test run at MST.

It comes pre-built, so you didn’t build it yourself. This means when something goes wrong (and it will), you will need to learn how to fix it. If you built it yourself, you would already be familiar with how the car works and goes together.

The RTR electronics are meant to just get you going. There are a lot of electronics out there that are better quality and more pricy. There is a reason why people are willing the drop the extra cash on them. The electronics included will get you up and going, but you will be upgrading soon. This is a key point.

You are not really saving money, you are just able to get started for a lower initial investment. It is the cheapest way to get into the hobby.

Base Kits:
Yokomo YD-2E and YD-2S
MST RMX 2.0s
These chassis kits come in “kit” form. This means you build it yourself. We always recommend this route since knowing how it all goes together is invaluable. You will need to fix it on occasion, so either you become an expert from the start, or you struggle every time something goes wrong. All 3 are mainly plastic and are considered Entry Level. All 3 drive excellent out of the box and all 3 can be fully upgraded. Also note, these are all very capable chassis out of the box. That’s not to say the upgrades aren’t needed or don’t make a difference, because they do. It simply means in the right hands, there is no reason you wouldn’t see these very chassis on the podium at your local comp.

Yokomo YD-2E and YD-2S:
Yokomo is the larger of the 2 companies and as of recent, have really been pushing the development of their YD-2 line. They have been steadily releasing new upgrades. Some feel it’s too often, some like the innovation. The YD-2 line also has a lot of 3rd party support, but keep in mind, not all the 3rd party products are good or even tested. We have seen a lot of “upgrades” actually hurt performance. So buyer beware. If you like constantly changing and upgrading parts, Yokomo is really the clear choice of the two companies I am discussing.

Based on the original YD-2 design, it has a Low Center of Gravity (LCG) setup, with a standard gearbox and a low mounted motor. It was intended for standard to high-traction conditions.

It has introduced a tub style chassis and lay-down gearbox. The lay-down gearbox mounts the motor high, High Center of Gravity (HCG) giving it more “Weight Shift” and theoretically more traction for standard to low-traction conditions.

MST (Max Speed Technology) RMX 2.0s:
MST has been a player for a long time and has always put out high quality products. There is not a lot of 3rd party support, but MST always brings upgrades that work really well. They designed the chassis, they design the upgrades, it’s a winning combination. Their upgrades are some of the nicest I’ve seen, but typically come with a price tag to match. If you like upgrading once and sticking with it, MST is the way to go. They typically will release a couple versions of . upgrades, and then they move on. You can count on their upgrades making a difference and also being top quality.

RMX 2.0s:
In my opinion the RMX 2.0s was MST’s answer to Yokomo’s YD-2. The YD-2 S appears to be Yokomo’s answer to the RMX 2.0s. The RMX 2.0s comes with a bevel gear gearbox giving it a more compact design. It also allows you to chose between mounting the motor high or low, giving you a High Center of Gravity (HCG) and a Low Center of Gravity (LCG) setup in one chassis. It’s nice to be able to experiment and find what fits your driving style without having to commit to an entirely different chassis.

This is based on the many customers who come through our doors here at Super-G. We have worked with many people who have gone about this in so many different ways. We would just like to save you guys the frustration if possible.

For someone just getting into the hobby, the Yokomo YD-2 line and the MST RMX 2.0s are the leading choices. These are the most popular Rear Wheel Drive chassis with the most support and knowledge at the moment. I own both and can recommend them both very highly.

If you stick to these 3 or the upgraded versions, you will be on your way with a solid chassis. What you do from there is up to you, but you can feel confident it’s not your chassis holding you back.

MST RMX 2.0s – A Better Battery Holder

I’m always about telling it like it is, especially when it comes to R/C. I don’t play favorites to any brands, or hate on any brands, I just like good stuff. As much as I like MST’s RMX 2.0s, there is one thing in particular that I absolutely hate. THE BATTERY MOUNT!

In particular, their use of those little body clips. I’m surprised they still use this method, because in my opinion it’s just a cop out. I have been using Velcro for the past year or so, but since it’s a little bit of a tight squeeze between the top supports and the bottom deck with the Velcro on both the battery and the bottom deck, it’s been less than ideal. The only reason I have opted for Velcro is I hate the stock mount and did not have another option at the time.

Enter the Yokomo Shorty Battery Holder for the DRB/DIB – DRB-118L.

Notice the new battery mount is perfectly centered.

I found the existing holes in the RMX 2.0s chassis line up perfectly with the mounting holes on the  Yokomo Battery Holder. What I really like about the Yokomo holder is first and foremost, they don’t use those pesky body clips at every corner. In fact, they only use 1, but it’s really optional. I always run the screw the end cap pivots on a little snug, so it holds in place. It also naturally wants to stay in the closed position, so I’m not sure what the body clip would even do in this situation.

Battery Holder Open

Battery Holder Closed

The battery slides easily into the holder, and has no room to wiggle, yet it doesn’t tear into the lower corners of your batteries like the stock RMX holder does.

So if you’re like me, and want a better option for mounting your battery, give the Yokomo battery holder a try. It’s really a worth while upgrade, and I do mean upgrade. The only catch is you need to be running shorty batteries. If you are running the thicker shorties, over 3800mah, you can just put some spacers between the holder and the deck to raise it up.

Yokomo YD-2 or MST RMX – Which One Is Better?

Yokomo YD-2 or MST RMX 2.0s? How many times a day does this question get asked? Too many is the answer. There are as many opinions on this as there are people asking the question. People have their reasons for preferring one over the other, and some are misinformed and just keep spreading what one person may or may not have said or meant. I’m lucky to be in a position where I can try different chassis and different upgrades easily, so I want to share a some of my insight.

(All images will be of either the YD-2SX or the RMX 2.0s)

Yokomo YD-2:
A couple years back Yokomo shocked the R/C world when it released the YD-2. Before then, Yokomo was only offering 4WD chassis and RWD Conversion Kits for them. We can all agree they were ok, but less than ideal. The YD-2 came as a basic kit, plastic fantastic, but it was a sub $200 chassis already set up for RWD. Out of the box it was noticeably faster than most other RWD chassis out there. They went to a rear Gearbox design which looked very familiar to all of us who do, or have done off-road buggy. There has been a very loyal following for this chassis.

MST (MaxSpeedTechnology) RMX 2.0s:
About a year ago MST released their answer to the YD-2 with their RMX 2.0s. There was a previous chassis called the RMX which was belt drive and not very closely related to the RMX 2.0s. For this write up I will only be talking about the RMX 2.0s, so I will refer to is as the RMX from this point forward. About 3 months before the release of the RMX, there was a lot of buzz about it. Mainly about how the steering would be superior to the YD-2 and would drive well right out of the box with factory settings. When the time came, the rumors were correct. The RMX had great steering right out of the box and drove really well.  MST went with a rear gearbox as well. The RMX seemed to have a slight speed advantage over the YD-2. This chassis has gained a huge fanbase quickly due to the fact it drives so well with no upgrades. As long as it’s built according to the instructions, it performs very well.

Out of the gate, the YD-2 beat the RMX to the latest style of chassis. I personally did not care for the steering setup that came on the YD-2, but the rest of the car seemed to work really well. I did not want to go to an after-market steering system to make it work better, so I moved on. The RMX worked really well and their steering system seemed to agree with my driving and tuning style more. In addition, MST built into the design, the ability to mount the motor in the high position (Weight-shift). Moving the motor above the gearbox immediately changed the handling characteristics and transformed it to a real winner on low traction surfaces. Sometime after the release of the YD-2, aftermarket high-mount motor plates for the YD-2 started showing up all over, as well as aftermarket steering kits. These 2 additions really closed the gap between these two.

Fast Forward to today.
Yokomo has introduced a good amount of revisions for the YD-2 line. For some this is a negative, others see it as a positive. If you purchased the original YD-2, the YD-2 Plus, YD-2 EX, YD-2S, YD-2S Plus, YD-2E, YD-E Plus, and the YD-2 SX have all been released since then. The YD-2 through YD-2 EX were based on the same design, the EX being the big daddy at about 80% of the upgrades available from Yokomo being included in the kit. The YD-2S introduced the lowered gearbox and high mount motor for low-traction surfaces. The YD2S Plus is the upgraded version of the YD-2S. This year Yokomo introduced the YD-2E to replace the YD-2 and is now coming with a new and improved steering system. The YD-2E Plus is the upgraded version, and the new YD-2SX is the upgraded version with both the new steering system and the high-mount motor. You got that? Of course you do.

MST always does things their way, which is to release something that works well and they continue to build on it. They released the RMX and also the RRX (Rear Mounted Motor) which is basically the RMX with the Rear Motor Conversion included. MST continues to release upgrades for the RMX, all of which are top quality and some of the nicest parts I have seen in R/C.

Upgrades Upgrades Upgrades!!!
Of course we all want upgrades, right? Of course plastic is fantastic, but it’s not as pleasing to the eye. Plus who wants to roll around on their stock hubcaps on their real car? That’s what it’s like rolling the plastic. Nothing wrong with it, but nothing exciting either.

Yokomo produces some really nice upgrades. There is also plenty of companies who make after-market parts as well. Some are good, some are not, so you need to choose wisely. I usually give the manufacturer first shot since they are the ones who designed the chassis. As you can see, Yokomo produces some really nice pieces. I really appreciate their attention to detail.

MST also produces some really nice pieces. In my opinion, some of the nicest. What MST lacks in after-market support, they make up with their own parts. Notice the detail on the shock tower with the markings and slide adjustment. MST also offers the shock towers in matching carbon with the standard hole adjustments.

Yokomo Updated and Upgraded Steering. I have to say I really like this new setup. I will be the first to say I did not like the first round YD-2 steering, but the new steering really agrees with my tuning and driving style. Props to Yokomo for making this change!

MST released an upgraded version of their original plastic steering setup. It has agreed with my driving and tuning from day one. I was glad to see they made it nicer, added more adjustment, but kept it the same. I’ve always  been a firm believer in having the steering system ridged and with as little slop possible. MST has nailed it!

Yokomo YD-2SX!

MST RMX 2.0s!

Both look menacing!

Yokomo – 7 Positions (All High Mount)
MST – 4 Positions (1 Low, 3 High)

Yokomo just introduced their new style Adjustable Toe Blocks. These are my favorite style this side of what D-Like uses on the Re-R. Offset inserts make for quick and precise adjustments. Much better than buying separate Toe Blocks for each adjustment.

MST released their Adjustable Toe Blocks almost at the same time as the RMX. I was glad since Toe is such an important tool.

The Conclusion:
I am only touching on the similarities and differences between the 2 offerings by these top-notch companies. We have had a lot of people come to our shop so confused by the strong opinions from both sides. In the end, it closely parallels with the iOS vs Android battle. Each side has it’s pros and cons. You will have people who really love one over the other,  and hate one over the other for various reasons. You will also find there is a good majority that fall somewhere in the middle and will go with what they like at the time.

Some of the key arguments I hear:
Yokomo has a lot more after-market support, nobody makes anything for MST. 
Partially true – Although there are more companies who produce after-market parts for Yokomo, there are many products which are universal and will work for both. Suspension arms, knuckles, shocks, springs, servo mounts, hubs, wheels, body mounts, etc. Not to mention any custom work can use whatever your imagination can think of.

MST does a lot of research and development, Yokomo just keeps pushing out products and they don’t work well. That’s why you need the after-market support.
Partially true – MST parts tend to work well on the first release, however, Yokomo releases different options, some work better than others, but as long as you can get what works for you, you’re fine.

Presently I have a fully upgraded MST RMX 2.0s and the new Yokomo YD-2SX. They drive very close and I imagine with time they will be even closer. If I had to choose, I would have to flip a coin. The RMX at the moment is slightly easier to drive, meaning more forgiving, but I have had a lot more time with it. At the entry level kit I feel the RMX has a slight edge since the instructions get you a better running chassis. Both seem to be about equal after that.

My personal opinion is, you can’t go wrong with either. So which ever you choose, buy with confidence! We sell both at Super-G and carry the full line of upgrades for both as well. So this is as unbiased as it gets.  Hope this cleared up some questions and concerns some of you may have. See you guys at the track!

Rememeber, keep drifting fun and leave the drama at home!


MST’s Latest Offering – RMX 2.0S

MST (Max Speed Technology) has just released it’s latest RC Drift Chassis, The RMX 2.0S!

Here at Super-G, we happened to get the first shipment to the U.S., so of course we got right down to business.

Initially I had considered doing a Yokomo YD2 / MST RMX 2.0 comparison since that seems to be the talk on the streets, but I feel to be completely fair to both sides, I need to spend time with them and get them to the point I feel I their strong and weak points have revealed themselves. This can’t happen in less than 24 hours.

I would like to start off by stating I do not feel the RMX 2.0 has “copied” the YD2 as so many are claiming. If I had to really break it down, it seems both chassis have borrowed technology which has been present in the 2WD Off-Road Buggy scene for some time. Both are offering this style layout, both with different approaches. So the statement of so and so copied seems to be a bit of a stretch in my opinion.

If you are familiar with MST’s kits, you will find yourself right at home with the RMX 2.0. Everything is packaged as you would expect and the bags of parts follow right along with their instructions. I feel their plastic has been improved from the previous models. I have always felt their plastic was a little too soft, but I did not get that impression from this kit.

The front end has their new style steering which works very well right out of the box. If you use their specs, you will have a really good starting point. So far everyone who has tried it box stock really likes it. MST has chosen to mount their steering wipers to the bulkhead  instead of directly to the chassis. Not my preference, but it works.

MST has chosen to use inserts to set the UCA mounting points. Each one has 3 positions, but by rotating them, you can open up an additional 3 more, effectively giving you 6 mounting options with the stock inserts. Definitely a welcome addition to anyone who loves tuning.

The steering gives plenty of angle and the front knuckles have built-in steering stops to prevent the wheel from “Flopping” over. I believe they come stock with 6 deg KPI. The UCAs use the standard spacers to give caster adjustment. I was happy to see MST provided full turnbuckles instead of the solid links provided in the FXX-D kits. Yes, more room for error, but with the option to really dial in your tune. For those who don’t care to tune much, just follow the lengths they specify in the instructions and you’ll be good to go.

The RMX 2.0S comes with a sealed gearbox. Rather than to go with the standard “Stealth Transmission” inline style, they have chosen to use bevel gears to transfer the power to the wheels. This allowed MST to use their standard rear diff unit. I was pleased to see they provided a ball diff standard.

When building the gearbox, you are given to the option to flip the motor plate around and mount the motor up high in the weight-shift position. A very cool option In addition, you are also given the option to mount the servo perpendicular or parallel to the center-line of the chassis. So depending on your preference, MST has you covered.

The shocks that come with this kit are amazingly nice for a kit in this price range. I believe they are an extra for the first run of the RMX 2.0 Kits. Whatever it is, they are definitely the nicest shocks I have ever received in a kit in the $200 range. They come with 15 weight Mineral Oil which seems to work well on this chassis.

Overall, this is definitely a solid chassis in the entry-level price range. I wouldn’t hesitate for a second to recommend this for a beginner to expert. We all know MST will come out with their full line of hop-ups for this model, fully tested and working well as always. Many chassis require some setup to start getting around the track,  and even more before you start having fun. Not the case with the RMX 2.0S. This is seriously some good fun right out of the box.

First hands on look at MST’s ATK knuckles! (VX Dock and WUN Upper)

The new ATK knuckles are pretty awesome! Super small profile all around gives you amazing clearance. One of the Nanashi guys installed a set on their Yokomo DP as an alternative to the Wrap Up Next knuckles. 

Initial thoughts on them are they are tiny! So much room! Tried a 3mm offset rim then a 6mm, both had amazing clearance.  Full lock is pretty awesome as well.  

Silver VX Dock with Silver Upper Brace and Silver ATK all look so good working together! We can’t wait to see more ATK installs on other platforms!! YD2 anybody??

Overdose finally produces MST Hop Ups!

– Bumper support for MST have arrived to us –
OD2281 – 2283 Aluminum bumper support for MST

MST FXX-D IFS / Entry Level Chassis – Part 4 or 5

FXX-D Side

MST (Max Speed Technology) – FXX-D IFS Version
MST (Max Speed Technology) FXX-D is a RWD ONLY chassis. This is one factor that separates the FXX-D from the others featured in this entry. It is a purpose built and designed RWD Chassis. MST is extremely popular in areas other than SoCal, but with good reason. We have had many visitors bring their MST Chassis to Super-G, and we have always been impressed with the build quality and their performance. MST has always been a company that produces many upgrades for their chassis, which translates into upgrades that work and fit well. They keep their chassis affordable, but always offer a VIP version of their chassis, which is a fully upgraded version. This is one thing we really appreciate about MST, they offer an affordable entry to their top of the line chassis. Before going any further, I will say up front, this chassis wins my vote for Bang for the Buck, and Most Recommended for the beginner.

Build Quality – The MST FXX-D is basically the plastic version of the FXX-D VIP. With the exception of a few pieces, the entire chassis is supplied in plastic form. The plastic MST uses is considerably softer than that of Yokomo. As I stated in the Yokomo section, their plastic is what all other plastics are compared to, and MST plastic is not what Yokomo is. This being said, there are a few upgrades which we feel are necessary to make this a solid chassis. I would say MSTs use of plastic in these areas wasn’t the best choice, but it does allow you to get into this chassis cheap, and get some runs in before having to spend more on upgrades. Overall, the build quality is good and once the “necessity upgrades” are done, the chassis will be solid.

**Necessity Upgrades – We have a list of what we consider “Necessity Upgrades”. These are replacement parts for the weakest points on this chassis. The aluminum Reduction Gear Housing, and the Metal Drive Gear will provide a rock solid drive train. Aluminum Steering Wipers will eliminate the small amount of flex in the plastic steering wipers. This will provide very precise steering control. Turnbuckle Set – Yes, to keep costs down, the kit comes with Solid Links. Not a good thing if you want to do any type of tuning. These upgrades add up to about $100 on top of the cost of the kit, but ensures a solid platform.
FXX-D Front

Out of the box impressions – MST FXX-D where have you been all my life? I suspect due to the fact this chassis was never designed to do anything other than be a RWD chassis, everything was designed around this. Even with the solid links installed and using the supplied Gyro, the FXX-D is a solid performer. I found I could do laps without much to complain about. It wasn’t EXACTLY as I would want it, but it wasn’t bad. It will get the beginner up and running without any issues, as long as the chassis has been built correctly and the supplied measurements for everything is used. The IFS which stands for Inboard Front Suspension utilizes a cantilever suspension system which cleans up the front end and allows for max steering angle, works extremely well, and looks trick while doing it.

Performance – After the addition of the Aluminum Steering Wipers and the Turnbuckle Kit, I was able to get down to some tuning fun. What I found immediately was this chassis responds well to any adjustments. I was able to get it to my liking in one short tuning session. I did end up adding weight to the rear to balance out the slight front heavy feeling it had. This is due to the Front Motor design. Overall, I feel this chassis is the easiest of the 3 to tune and agrees with what I look for in a chassis.

What we have observed – For the beginners, this chassis has proven time and time again to provide the best experience for the people who are new to R/C and / or R/C Drift, mainly due to the fact that it performs right out of the box and gives a solid starting point from which to grow from. The number of upgrades and the quality of what’s available is quite impressive. We have seen great performance from many beginners, and we have seen some serious sliding from the more experienced. Fully upgraded, this chassis is quite impressive, but holds it own with a few simple, inexpensive upgrades. It’s rare to see someone struggle with this chassis. It happens, but it’s rare.

Recommended – As stated earlier, this is by far the best bang for the buck. It comes highly recommended without reservation for the beginner to the expert. If you are looking for a chassis to get you into the R/C Drift game on the cheap, or if you are looking for a chassis you can upgrade to the moon, this is a great route to go. It works right out of the box, but responds well to tuning. So if you are the type to who just wants to build and go, or you love to tune and tinker, you will be right at home with the FXX-D IFS. It comes with a gyro that works well, which is an added bonus. It’s hard to find negatives for this chassis, especially given the price point. If you are just getting into the hobby, you will be doing yourself a huge disservice by not at least considering this chassis.

$175 – MST FXX-D IFS (Includes Gyro)
$100 – Necessity Upgrades
$275 – Total (Plus Electronics)
