DO NOT EVEN THINK ABOUT THE "A WING"! I say this from experience. I have two PT-40s, I built the first one with the A wing because I thought "I am a beginner, I should use the beginner's wing" - WRONG! Way too much of an angle, it makes the plane very difficult to taxi, take off or land with any cross wind, and it makes the plane not as much fun to fly. I was going to buy a wing kit, but it was $75, a new PT 40 kit was $90, so I bought the full kit and rebuilt, much, much better plane to fly! Now that my trainer is limiting my flying I took my older PT-40, converted it to a tail dragger, cut the wing in half and removed all Dihedral, extended the rudder and elevator, put high rates on the ailerons and replaced the .46 motor with a strong OS .61 SF. It is a ton of fun to fly now.

The PT-40 is a good little trainer, I really like mine, but the A wing is a mistake, everyone who I know who has had one (this is 4 -5 people at my club) agree - do not built it! Good luck and have fun!
