Try a lower f/r toe setting as well , since your current settings might scrub speed, no matter what motor you switch to....

If you have a 35 tooth pinion, see if you can make a good mesh (before you run out of adjustment). That will give you 3.77 and should get you in the ball park. My 21.5 just lacked punch with the 3.47 you are running.

glennhl i like your thinking what is the timing on your motor. and is it a reedy.

i may have the wrong 21.5 i got part #253 i was told to run the part #284 for more tork and speed. that reedy motors

Reedy Sonic 540-M3 Motor SS 21.5 1S Spec with the 273 rotor is the best combo

Reedy Sonic 540-M3 Motor SS 21.5 1S Spec #284 is the one you want.

Here is a setup I have been using and things are going very well with it. I am running an old grey carpet that is 65 x 46 in size. The carpet grooves up pretty fast and we have better than medium traction by the main. We only get to run one day on this as the shop uses the carpet for other types racing during the following week and everything changes. This carpet is so old that it doesn't fuzz any more. My car sort of slides a little, but is fast, very much under control and I am enjoying it.

I run a Trinity D4 short stack at 48 degrees.

Is it possible to use the alluminum chassis in low-medium grip environments with this car? Can you mitigate the lack of flex with softer springs and oil?

I have gone back to the Graphite chassis. Couldn't make the aluminum work with our grey carpet. Its a 50/50 at our club, some guys went back and some guys like the aluminum. I think when there is a more flexible aluminium chassis available like the Fenix I will try it, but have no intention in going back to the AE aluminum chassis.

I order the #284 today do u run this motor if so what is your gearing.

I am thinking on changing the back diff lube from 5000 to 7000 is that the right thing to do in 21.5 on the black carpet.
