Re: KCM Question

[nblattau-at-isrmail.isr.umd.edu]

My brother ran his Marder chassis around with KCM drives.  
Some quick observations:
1.  Speed was okay, but this was a very light chassis, still 
not close to EV warriors.
2.  He jammed a track on some rocks and the KCM drives 
started skipping gears.  This is probably by design and/or 
because of flexing of the plastic gear housing.  
3. On the UN armored car that sports for KCM drives power is 
not a problem.  However, speed is still slower than EV 
warriors.  Solution may be to run 18 Volts with some cooling 
to prevent overheating.  This is still not been tried.
4. 10 inch tires would also boost the speed, but not scale. 
5. Battery life was not an issue running 4 in the car.
