I like what I read as for the gas conversion for a 4 stroke is their a company that makes this? also I have to look at batts receiver and transmitter. as for a plane I agree on the polyhedral my thoughts are a old timer style cabin for the fuel and batts. also most are very easy for anyone to take the controls. Maybe a buzzard bomeshell, playboy? Another thought I have is start early before light have lights and a batt. on board that I can drop at day break so I can get the most flight time as for I live in Ohio and only for a very short part of the summer do we have that much light.I need all the help I can get as you can see it sounds easy till you really get into it.
