I was running a 8t gea ron 43 t pinion (PN w/ ceramics) , I bumped it up to a 9t and now the car seem slower. The only other things I added was a gyro and front spring cups. I know I am slower coming off the corners but the top speed is gone. Is it my imganation or is there a real difference. I got tired of keeping up in the technical part and then getting blown away on the straight aways. Or do I need to do anything with the diff. Any help would be great.

that's kinda odd... if anything top speed should be faster.... acceleration to get it up to top speed would take a little bit longer... try taking out the gyro and see if it is any better... try going against another mr03 with a 9t...

how big is your track? maybe it isn't big enough for a 9t to get it up to it's speed...

that's all i can thing about at the moment... hope this helps...

Check your gear mesh. You need to adjust the gear mesh after switching to a bigger pinion. The motor pinion and differential spur gears mesh are probably too tight.

good answer tjay... check the spacers that go into the motor pod, make sure you are using the correct one for the 9t... :D
