I'm gonna try to make this short. Started my 2wd season with the Durango. Hated it. High quality, but couldn't drive it. Bought my son the B4.1 and drove it for a few weeks. Easy to drive but full of slop. Bought the RB6 and the Losi. Losi is very flat and feels good on the track, but I really wanted the RB6 to work for me. Finally after some changes to the car, I am within .1 of track hotlap. Qualified 2nd in the A today and the car was a dream to drive. Very pleased with everything about the car. Very high quality, durable, design is awesome. Love this car.

I just listed a couple spare bodies for sale on here. Can anyone verify this is an RB6 body and not an RB5. Had both at the same time and both are sold and have the body and undertray left over. Thinking it was for the rb6..

I am, but it's not the best fit. I hope they release one for the rb6.

Ran 30/-4 (26 caster) last night, and the car felt really good! It was a bit tricky making sure I had my caster inserts in backwards, correctly Qualed 2nd, and finished 1st with it. Car was very very good. There is a video of the run out there somewhere.

I think 30 / -4 gives great steering in the infield, with great off-throttle rotation.

Agreed, I like that many of the settings are adjustable in smaller increments, I've found a balance that is good with the car, just need to learn how to drive it aggressively and not crash every other lap

Any particular color? I only know of silver (xray), blue (kyosho, xray, associated) and gun metal (kyosho, losi). I think TOP makes red ones for their sedan which could be an option. There might be other aftermarket options available for you but that I can't think of any right now.
