Hello,
Let's introduce myself. My name is Michel Verbruggen.
A couple weeks ago I bought a m18. The setup is:
speed 300 motor on 7.2 V
gm 4R speedcontroller
6 cells 1100 mah
42t spur en 21t pignion
What's the problem?
My friends have almost the same setup. (Some people drives whit 5 cells). But the are going faster. Not a little difference, but a lot...
First I checked if every bearing (wheels and diff) is going smooth. I removed a the grease in the diff. Yes, it makes a little difference, but not big..
I connect the batterypack direct to the motor. (the speedcontroller was also connected, but in this setting usseless). The motor make a lot of rotations, but not more than the setting with the speedcontroller between the batterypack and the motor.
Do you have any possibilities?
Thanks, Mish
