(...) You might also use a fast 2838 motor (URL) to direct-drive the ball throwing wheel. A friend used this setup in a GBC module (URL) that worked several hours without motor problems. Philo (19 years ago, 18-Jul-05, to lugnet.technic)

Update: there are now two motors driving this thing. They each have an 8 tooth gear that turn a 40-tooth gear placed between them -- instant torque, but less output speed. I put another 40-tooth gear on the same axle as that one and connect that (...) (19 years ago, 18-Jul-05, to lugnet.technic, FTX)

I thought of something else. I'm testing this thing with an RCX, and could it be that as the batteries get weaker the motor loses power, which makes stalls even more dangerous? (19 years ago, 9-Jul-05, to lugnet.technic, FTX)
