As stated, the master airscrews are awsome for learning. You can drag it down the runway and not hurt it. Touch a wood prop to the ground and its gone. I fly wood on a lot of planes, but since we went to a gravel runway, I can't do it. I hadn't broken a prop in over 5 years, now with the gravel beating the prop to heck, I replace one almost every flight. Whoever came up with the idea of a gravel runway needs help. Sure hope we get that fixed soon. It really bites.
Flew off grass before that. It was awsome.
