Thanks in advance, Tiago
Still waiting for an answer. Even if you haven't drived a 22 before give me your feedback on the RB6.

I have owned a 22 and also an Rb5 but haven't built/ran the 6 yet. I struggled with traction and rear grip on my 22. My Rb5 was just plane dialed and had the perfect amount of rear grip and also steering. I know that lots of guys have gotten their 22 cars pretty good but I prefer the K car shocks and overall quality. Looking forward to the 6!

Thanks,I was wondering why you had extra screws on the rec plate lol.. nice..

+1 The 22 had the most side bite of any buggy I had out of the box, but rear traction was an issue. Out of the box the RB5 SP forward were great and didn't need much tweaking to be good. Very durable cars(especially since I drive one!). I've had: B4, Xfactory X6^2, 22, and Kyosho RB5s. The only car that compares to the RB5 out of the box is the Xfactory, but its more suited for high traction. I kind of wish I had one still with now a hex conversion hrmmmmm.

i never owned a 22 but i driven a couple that where well set up cars, the car always looked awkward on the track almost like the front tires arent conected to thecar. also the diff has got to be the worst on the market, the steering rack is a target for problems as far as dirt wear and if u go aluminum- then stiction.. i'm not telling you what to buy or that the 6 is better but these are all 22 issues ive encountered without even owning the car.

ps the 6 is better

On Friday night a fellow local racer had his rack lock up on his 22 and that was that.....

The diff was ok once you replaced the diff nut and screw, got new rings and new balls.....oh never mind. I ended up installing a bfast in my 22 and it was perfection.

Back on topic...I feel that the 6 will be as good if not better than the 5....Hence the reason they would make a 6 at all.
