Hi Dave, My question pertains to props. What is the best prop for the 160 if I,m going to be using it for aerobatics and 3D flight? The plane I,m going to be flying is a Funtana Pro 2m, 10.5- 11 lbs. I was hoping to be able to use a 19x8 apc at 8000-8500rpms. thx Dave

You might also try a 20x6. For 3D you want big diameter, low pitch. Also remember that you might want to try something smaller. It won't hurt the engine to run it in the mid 9's, and throttle response will be quicker with the smaller and lighter props.
