John,
I order the servo controller, for the motor I looked at what Innovative had to offer, Since I will be testing less than 6" diameter props (likely less than 5.5") this motor looks like it would fit: Cobra CP-2210-2200 Champion Series FPV Race Wing Motor, Kv=2200. I could order two of them and use one for the test stand and use the other for a test ship. What do you think.
Best, DennisT
