Pick a brand that is locally readily available and stick with it. My small town hobby shop stocks Losi so that's what I run. Lots run Associated.

Has anyone successfully mounted a motor fan? I saw there are some 3D printed waterfalls with fan mounts for the B5m and 22 but didn't see any for the RB6.

Kiddo and I each put it on the box today. Him in novice and me in 2wd mod. The front end is getting some play in it but dang this thing can take a beating. Was fast and smooth all day. I got faster as the track dried out and got slicker. I would up with 24/76 gearing with a Tekin 8.5. The motor was quite warm after a 10 minute main but you could still hold your fingers on it.

Default step by step 3 Gear build pt.1

For anyone interested in building a 3 gear trans for their RB6 before Kyosho releases their own I have a few good photos of how I built mine. It may not be perfect but I run mine with a 6.5 Mod on carpet and have had no issues. You will be using the 3 gear rear motor case included in the kit for this mod.

The first photo shows whats going to end up being your left side of the 3 gear trans case. In the picture I have the original case on the left and the shaved down version on the right. The bosses just need to be Dremeled carefully flush with the case. Then trim the first step of plastic off where the top shaft perturbed.

The second photo again shows the original case with the modded version to the right. The hole where the top shaft was originally needs to be blocked the from the inside of the trans case with approximately a 1.5mm or 2mm shim. I found that the plastic slipper spacer UM603B glued in with tire glue works perfectly.

The third photo is showing the top shaft. Unfortunately the top shaft has to be shimmed away from the bearing a little bit or the teeth of the gear chew into the case. I used just one plastic front axle spacer UM714 to keep it spinning free.

The fourth photo shows the right side of the trans case. A body reamer was used to make a hole where the top shaft will exit from.

The final photo shows the spacer UM508C and how I cut it into pieces to adapt to the new reverse orientation it will be in.

Default step by step 3 Gear build pt.2

The cut up motor spacer supports the bearing and is still keyed into the motor plate. Next you need to shim the motor plate 6mm from the trans case. W0142GM spacers work really well here and match the color of all the other aluminum bits on the car. You need a lot of them, I used 20 total.

Tighten everything down and be sure everything spins smooth and free.

I was lucky to find a gear cover that is 3d printed and sold by a cool guy on Facebook.

Mount everything up in your buggy, hit the track and air it out!

Umm, what transmission case did you start with? Seems like some pertinent info to include. Oh, you run on carpet, makes sense.

Any word on when Kyosho will be releasing the optional three gear mid motor tranny?

Just finished up the Dash 4 Cash race in Houston. First time running my new RB6, had the Zachary Rogers setup on and it was awesome! A2 I finished 4th right behind some really fast guys! This is the best 2wd I've driven by a long shot...

Good job. Those are some big names. If you would have had some 19's instead of those couple 22's you could have beat JR.

Yeah, I had a couple bobbles but I have no complaints about the car. Locally guys make fun of me because I change cars every other month trying to find a car that suits me best, this one definitely is for me.
