I appreciate all your input. I like the OS .46, and since my instructor suggests I use it, I'm going to listen to him for now. A differnt prop like an 11x6 or 11x5 might be a better choice for it through training. I will hang on to the Mag .40 and put it back on down the road when I'm out of training and my instructor wants his engine back. Any other tips, suggestions or comments are welcome.
