Q-tees were a lot of fun. There were pilots who used them for pylon racing. What a ball. The original Q-tee was what it was because you could build it all out of stock 36" wood. I had two with extended tank .049 Cox engines. Flew good but I missed the throttle so I blew it up to
1.5, 54" span and put in a .15 engine. Real fine airplane. A flying buddy said it was the best airplane he ever flew so I gave it to him. When it went to the great hangar in the sky he returned the radio and engine to me. I now have a 54" Q-tee with barn door ailerons and an
OS.20 FP. A very nice airplane. Build the thing. It's so simple the plans are self explanatory.
You will have so much fun you will want more than one. Don't forget the extended tank for the Cox. They are available from Hobby Lobby. You can also use much lighter electronics that are available now instead of the standard size we used in the old days. Now that I'm thinking of it I may have to build a couple more.
