What makes you say that? Are you sure there wasn't something wrong with the setup? I'm just curious because I havnt driven one yet but I'm buying one tonight. Did you add weights?

Its aluminum chassis car its not going to be as easy to drive as a ae but when you get some time on it and figure out how to tune it the car is awesome! There is so much to tune on it and I still haven't tryed everything yet. The car is by far one of the most stable cars I have driven.

Now that's funny.

My RB6 is dialed, got fast lap and tq'd round 1 and second in the main just yesterday. With my b4 I was consistently in 6-7 spot.
What I have the balls to say, is anyone that complains about an RB6 probably can't tune for crap. You can't just slap a pro drivers setup on it from some random track you've never ran on and expect to win, gotta be willing to make the adjustments needed to tailor the car to every different track. Once setup properly the car is a rocket ship.

The real problem it seems, is that people can't tune their cars anymore. Yes the Kcar can be hard to drive until its right, some buggys are easy to drive no matter what but even with those buggys you won't be able to hang with the fast guys until learning proper setup.

I ordered it and cancelled it soon after. Can you post pics once you have yours. Its good for a mid motor car but I run mine RM so wanted to see a racers rig rather than the factory pics .

My plan with the buggy is to start with the box setup but I figured since i'm going to be running on a smooth carpet track that right off the bat I'm going to put in yellow front springs and red rear springs 30wt losi in the front and 25 losi wt in the rear. Mid motor setup. with the avid slipper setup. I havnt got an aluminum steering setup yet, what do you guys reccommend?

Personally I love my RB6, I was very cautious in swapping from my TLR22 but now I have done it I wouldn't go back.
The car is easy to get right IMO, I got my MM carpet car set in three heats.

I do have one question I am finding I am cracking front and rear wheels often and its not due to crashing as I crash less than when I first started with my 22 and never cracked a TLR wheel.
Is this common?

I run MM and I just ordered the RF and RR Rear Suspension Holders. What letter bushings should I use to gain more rear traction? Thanks

Strange that you are cracking the wheels. I have wheels that are over a year old now and have been used multiple items. What glue are you using and if you are removing the tyres, how are you doing it?

It is perfectly normal to crack the inside bead of a wheel--its the weakest part. Wheels don't last forever. When I go to soak tires off wheels to reuse wheels, it's normal that fronts sometimes are not reusable. Its less common on rears. I've had this happen on every brand of wheel.
