There is a great build tread in the ARF section of these forums abouth te Phoenix Super Decathlon. I read each and every post while I was putting mine together. Maiden flight was week before last. I fly mine with an OS 55AX, spinning a 13 X 6 APC prop. This combination gets it into the air quickly and power for all that you want it to do. I had no handling problems at all. Take off is tricky because of the short fuselage and the fact that is is a tail dragger. I set my CG 90mm from LE. Manual calls for 100mm. Flys perfect for me at 90. but a little nose heavy while inverted. The decathlon was my 3rd plane. I rated it here as a good second plane, but I had alot of stick time on my first one. Setting up and tuning the engine is an art within itself. You'll need the help of someone experienced to get it dialed in properly so that you don't dead stick in flight. Other than that, it flys super, and lands great. Alot of posters were saying that you need to land under power, I tried that on the first flight and go some pretty good bounces when landing, the next flights, I chopped the throttle on final approach and it glided right in and landing softly with very little bounce. I have six flights on it know, and the more I fly it the more I like it! for 80 bucks RTF, its a good deal! wouldn't hurt to get an instructor to do the maiden flight for you.
