God, I feel old. In this case, a "whip" is referring to the car itself and not the mid-air front tire flick. To call a car a "whip", is an old term from a couple of decades ago. I didn't think anyone used that term anymore.

Until Jeremy McGrath put a name on it I didn't know the thing I was doing in 70's was a " nac nac " Definitely don't remember ever whipping an rc in the old days but now the control especially on a 4w buggy is unbelievable. Airing it out and saving it is one thing but seeing the same "whip" lap after lap is a true joy.
Now, back to the RB6. Anyone using the AKA wheels ? What do you think ?

They are a more flexible than most other wheels on the market. With the optional wheel insert they are comparable in flex to others. The softer more flexible wheel gives a bit more traction and by adding the rear wheel insert it will free the car up a bit. A very nice tuning aid.

Will using the mid motor config change the gear ratio with the having the 4th gear? Also does anyone have a good starting point for 17.5 gearing in mid motor config?

It does not change the gear ratio because those two gears are the same size.

Idler gears (regardless of how many) no affect on the transmission ratio no will it affect your rollout.

Try a 30/69 for 17.5.

I was getting ready to go full Devo before it was explained to me. I think I did gain some new street cred.
