I think if you have an FRC team near you, you should go visit them and see if they'll let you just pick through their boxes and see what they're willing to give you.

My team still has boxes of mismatched transmissions, Power Wheels transmissions and old motors that I'd never put on a competition robot, etc. If I knew a kid was going to actually use them, I'd be pleased to give them away.

The mentors and seasoned members can give you advice too. Way better in person than on CD.

Good Luck!
