3.7 VDC MOTOR WITH PROPELLER

Not the right propeller

This definitely isn't a very good propeller. The motor and drive may be fine for a small airplane or car, but the propeller is not a real propeller, except in the visual sense. Granted, this is a small motor, but it could do a lot better - it could probably even swing a propeller double the current size. Don't plan on this being terribly usable as-is. I kinda wish I bought one, but I bought three.
