Hello Everyone, I am new to this site and this is my first post. I have recently bought a "used" Airfield P40 1400mm Warbird from a guy along with 2 other planes. This plane is a "little" beat up but not bad at all, easily fixable. Here is my question. It does not have the original 3 blade prop that came with it and I can't find one to buy that isn't on back order. So I was wondering what size 2 blade prop should I use? I was going to try a 12 - 8 prop but wasn't sure if it has enough power. The motor is an 850 kv and polan on using a 3s 2200 Mah battery. I also searched for the correct C/G and decided to start out with the manufacturer suggestion of 85mm back. Any suggestions for the C/G would also be helpful. It looks like I should probably get the 2 flaps working to make landings a little slower? Does anyone agree with that? I've been flying for a little over 2 years and have never really flown one of these birds that appear to require fairly fast landings.....
Any info at all about this plane would be very welcome.
thank you very much

Put the CG where the manufacturer recommends. Dan.
