I'm pretty sure using a small motor as a sensor is legal by the rules regarding to custom circuitry, but it doesn't hurt to double check.

Joel,
It is best to check with FIRST Q&A regarding legality. I am guessing that they would not allow this device as it is a motor and would generate a signal more powerful than other sensors available.
Why not use an encoder or other sensor designed for this type of measurement?
