Hi John,
You are on the right track and what you have should work fine for what you want. I agree that your battery and speed control are a bit big but this is a learning process for you and they will work well enough for what you want. The only place that you might run into a problem is with that motor. I had one so I know the issues with them. Its a bit big too but again so what, you have it so use it.What I don't like is that shaft. They are 4mm and soft. So I would cut it down when you get your collet so that there is no excess between the collet and the motor. Then I would make sure your prop is balanced. Lastly, forget about the spinner. if there is anything even slightly out of balance it will vibrate till the shaft shears off. Good luck with your setup!!!
Will
