標題: Tamiya 540 25T Motor with Grasshopper
Hi brothers, I have installed the sport tune 25T 540 motor into my grasshopper, however, I have 2 questions.

1. When reversing the motor, a lot of sparks and the motor is very noisy (there is only little spark when forwarding)

2. According to the motor spec, it runs on Gear Ratio 6.5 - 7.5, but I dont know the gear ratio of my grasshopper, can any brother help?

Thank you.

Is 18T instead of 25T pinion? It should not too loud. I using 6.5T brushless 7.2V full bearing.

for your reference!
