已经不是新车的XPRESS MRR2

C.hing,
HOw big is the Pinion gear you're using in 8.5 TURN ? I feel the car  very NOISE when Im using the ECpower ? Is that normal ? And the ESC cannot use 100% Forward speed , I turn it down to 65% speed only..... but the speed similar to 23Turn


THKS.

I use the SpeedMind 64P 30T gear. And I think my car is not quiet too.
Why don't you set the ESC 100% forward speed? Is the ESC have any problem?

IF I set it 100% forward speed , the Belt seems flying...and the car cannot push forward ,because the speed of the motor too fast ... HOw about you ?
I use 64 pitch , Original Spur gear and 40T pinion gear, is that match ???
This car really NOISE

40T is ok for 8.5T motor. I use 30T  pinion gear 100% forward speed and the car accelerate very fast.
Maybe your belt or ball diff have some problem? like the ball diff is too loose? Or try to chang ...

Yeh....maybe the belt is too loose , but how to make it tight ?

Thanks...

THank you very much brother..... Really the Ball Diff is too loose, after I tight it more better now....

師兄,你覺吾覺轉向比較差?
較得太盡,前面兩個轆又會磨到底板辺, 較得太開的轉向度又吾足?!

May I know what brand of the Li-Po battery U're using now ? The Maximum is 25C or 30C for the EC power ESC ???   Thks......
