Going to switch to a low pro servo (-15g).

I've added 40grams on the rear bulk head where the sway bar mounts, and 50gram plate under the battery to get it legal.
Appreciate the input seems I have some wrenching to do....thanks!

Finished up my kit. She drives beautifully, took her out for a first spin tonight Love how it jumps, incredibly smooth landings like it just floats on the ground.

Well a hobby shop in japan told me yesterday that they are not released yet and they can't order them, but should be out be the end of the month.

Seems some people got lucky and scored some from kyosho america. I say they will be everywhere by February.

Likewise I really like it simple but effective.
I normally just paint my cars one colour because I can't paint

Kevin, I'm using ur setup for my mid motor car (the one with rt6 mod for the battery) nd the only thing I'm lacking is corner exit traction. What can I due to help rear end traction. The front end is great! Thanks

I just installed the UMW705, UMW706 rear hangers with adjustable inserts. The rear arms cannot fall under their own weight as soon as I attach the rear motor guard. Before that the arms are loose. No matter if add a pro-squat shim or not.

This doesn't happen with the UMW514/515 rear hangers (RB5). Does anyone else experience this? I use the LAW32 delrin bushings (I don't think this is a factor). Thanks,
