Finished the super cub and test flew it this past Friday. This is a beautiful airplane. It went together with very few problems. The kit had 2 left rear wing struts and no right rear wing strut. After a call to Dave Patric I got the correct strut within a few days. The plane has a Saito 150 for power, Hitec HS-635's on ailerons, elevator, and rudder. Standard servos on the throttle and flaps. 5 cell 1700 Ma Nicad pack. Master Airscrew 16x8 prop. Dave Brown 3" spinner. 20 ounce Dubro Tank (a 16 ounce tank would be more than enough for this motor). Slimline Pitts muffler. Futaba 7CAP transmitter. I put the battery and receiver as shown in the directions and it balanced just a little aft of the center of the CG. Total weight was 15 lbs.
Test Flight: Temp- 50 degrees. Winds- light.
After checking the surfaces for the correct deflection and then letting another pilot double check, I fired up the motor. The Saito 150 is a great motor. After only one break in tank of fuel it will idle down to 1400 RPM and stay there. Take off was very easy. A few clicks of down elevator and right aileron and the plane was in trim. It didn't have unlimited verticle but it had more than enough power. Big loops from level were easy. Stall turns were no problem. I put in the recommended 20% aileron to rudder mix and it seemed to corner very nicely. Landings were the best part. This plane will really slow down, more so than I am used to. It is really fun to land. I had about a 5mph head wind and I tried a landing with full flaps (as per the recommended full flap throw setup). It is amazing how steep an angle you can descend with the flaps on and not pick up air speed. I did mix in 8% of down elevator with this flap setup.
After the first landing I noticed that the screws for one of the landing gear spring covers had come loose. After tightening them I took it up for another flight. I flew on high rates for all surfaces (I feel that the low rates are too low). I added about an extra inch of rudder throw and put the elevator expo to 40% from 60%. Rolls are cub slow but not bad. Spins were at a good rate and were very easy to come out of. Length of the field knife edge without loosing any altitude were quite easy. With a little mix the knife edges would be simple. Inverted flight required just a little bit of down elevator and was very stable.
I assembled and test flew this plane for a friend. I am not normally a cub fan but this is an incredible airplane. If you want to fly around slow and cub like it will do that, but it is capable of much more and it is the best looking plane I have ever put together. I really enjoyed flying this plane
