Picked up? You must be close...

I agree, a chassis would be nice.
My RT6 needs one. There is a race on now between my kit to my LHS and some 3 gear boxes to my house.
My RZ6 still has to be put together before the 6.6 comes to town. Ouch, could be worse...

Dif is the same ball dif as previous rb6. Parts that are different are chassis, side guards, rear bulkhead, trans cases and larger idler for laydown trans.

Part number um731 is the part number for the Rz6 chassis isn't it? Is it the same at the 6.6? Doesn't look like it

RZ6 chassis is different than the RB6.6.

RZ6 part # UMW731
RB6.6 chassis is UM731

UM731 does not come up on A-main or Kyosho America's site.

So, after I put my laydown in with the new rear bulkhead, you think I'll be able to use the new 6.6 body if/when it's available?
