It comes from my Tires !!! F.... ! So much time spent to glue them and they are TOTALLY unbalanced...... F.... F.... F.... !
So at high speed my motor works a lot to keep the speed against the heavy vibrations...


13 T pinions with 1520 1Y, thats just cant be!!!!! This motor with good balanced tires should be able to handle 22T pinions without issues... !
I will have to buy some new tires already glued and balanced... I am sure that is where I lost 20-30 degre on the motor...
Does somo one of you know some good one (tires) ?
