Re: gearing problem. Help please!
Yes you can still use the Van Door Motor from Taigene that is in the kit.
As to a 500 to 1 gearbox with the Chiaphuas as input, this is going to be tricky.
10 RPM is mighty slow.
But if you insist on such a high reduction, I recommend using some sort of Jack Screw for the last stage. You can get relatively effecient ones with ball nuts. If you try to go with a straight spur gear gearbox, you are really going to have to beef up the last several stages. 1000N-m (2000N-m if you use 2 Chiaphuas) is a LOT to deal with, requiring very strong gear teeth.
