Thanks for all the info. I was just concerned that an APC could be dangerous on a gasser. I can easily go to the local hobby shop and by a 20 X 8 APC or Zinger if I have to, but the better props are harder to get. I did buy a Xoar but they only had the one in stock. I wont be doing any major aerobatics, just basic stuff and having fun punching holes in the air. Thanks again for all the information.
