Nothing special except maybe not overtighten the case.
People tend to run 1000 to 3000.

Heard Kyosho have steel gears available for the 1/10th onroad cars and they fit.


The car is really awesome, ran it only as a Mid motor.
Very happy, they did a great job on a lot of things.
Thanks Mojo Tom

Trying to find the o-rings. Anybody know exactly what part number they are?

Well I started the build last night, All that is left is shocks and installing the electronics and the body. 2 problems with the build.The kit was missing a front steering block pin and the battery foam(supposed to be 2 pieces) was 1 single piece. Other then that it was a very easy build.

Has anyone ran saddle packs in the separate configuration? I have a brand new Orion 5500 90c and really don't want to buy a new pack if I don't have to.

Default first race meet out !!

First race meet out with the rb6 tonight and smashed my PB in qualifying by 17sec qualified 2nd in the A main and finished 2nd with a new pb for the race by a whole lap ........ loving the on and off power steering compared to my rb5 wc.... overall just feels more constant to drive less on edge !! happy so far
