The only thing I see with you test stand is that the tank may be low. You may want to raise it up.

As far as running the motor without propor spinner. That is a huge NO GO. You can get by without the spinner, but you have to have a prop on it. The motor is designed to have a load on it and running without the prop will wind up damaging the motor.

As Geistware said, it would probably be easier to just run the motor on the plane.

hope this helps.
