How does the rb7 compare to the 6.6 on high grip clay? Been out of the hobby for a year but still have about 4 extra sets of MIP pucks bagged, a few diffs, and a bunch of parts so thinking about getting one. Thx

I also upgraded my RB6.6 to 7 parts. The changes are not dramatic, but they definitely help, especially front gull-wing arms, and suspension geometry. For high grip tracks the RB7 is a much better value since all you need is the included laydown transmission.

I just ran the rb6.6 rb7 hybrid on carpet for the first time. I have all rb7 parts except for the chassis. I am wondering how much better it could get? This thing does everything I want it to do. It could maybe use a tad more steering but other than that it drives like a dream.

I've done the same to my 6.6 and went to the RB7 plastics, made a good improvement to the car (needed to get the droop right on the front when using the rb7 front arms, i went with long shocks end then bought the proper low profile front carbon tower)
Anyhow put on the RB7 chassis a few weeks ago, what a difference! as its a shorter wheel base it gives the car loads more steering and the flex characteristics are very different, well worth the money!

Do you guys run aftermarket wheels on your RB7's? I tried on a pair of wheels/tire combo from my buddies AE RC10 6.1 and was alarmed to see that the offset was sketchy and i couldn't even get the nut to tighten up to the threaded portion. I wanted to get a few sets of black wheels for my RB6.6 and my Step son's RB7, ones that aren't white... or green..

Akerman setup
Hey guys I hope you can enlighten me with this particular part. So with the Ackerman it has an arrow going up, but in the setup sheets you can choose up or down. When I built the car, I built as per manual. Arrow facing up. Then the other day I installed it with arrow facing down and i lost half my steering. If you could take photos of how it's installed with arrow facing down that would be great and the reasoning.

Flipping the rack is just that, spinning it around so that the arrow points to the back of the car. Be sure though that you swap the balls so they point to the front of the car again and reset your front toe. That's my suspicion on your loss of steering.
May also need to add/remove steering via your radio too due to this change.
