Major mechanical problems....

You want to reduce the output speed of your motors using those 90 degree gears. But you've increased the speed by putting the larger gear on the drive, and the smaller gear on the wheel. Reverse the two gears (smaller on the drive, bigger on the wheel) and your problems should be solved. Hope this helps!

YES YES YES!!!!

what Ben said!

you assembled the transmission backwards - the small gear MUST be on the motor shaft and the large gear on the wheel shaft

man! your wheels must be spinning a couple thousand RPMs when you have them off the floor!

also, it would be better to get the original drill motors and white gearheads in there instead - they are geard down lower than the Chips - and the FIRST transmission was designed for them.

If your motors were destroyed you can buy replacements, you can even buy complete Bosch drills at the hardware store and put them in tonight - it will cost you more, but dropdead date is only 3 days away.
