Default RE: P-38 from KMP

Well, after six months of modifying, it flew. I put three flights on it today. It took off in about 10 feet mostly because it needed 5/16" of down elevator to fly straight because of the +5 1/2° of wing incidence and - 1° of horizontal stab incidence. Other than that no trim was needed. Inverted flight needed no additional down elevator after the plane was trimed out for level flight. I didn't use flaps for take of but did use about 3/8" for landings.

What did it take to get it into the air? First there were many quality problems. One boom, one outer wing panel, the retracts, and the canopy were replaced due to various defects. The cowls though not replaced had hairline cracks and were fiberglass on the inside for additional strength. The replacement retracts were also marginal and I did use the mains though I replaced the nose with a spring air unit. I like power so I installed two GMS .76 ringed engines and they balanced the plane perfect and have been great in the air. I put in Sullivan 12oz tanks for 20 minutes of flying plus reserve. I installed twin elevator servos next to the rudder servos and use Dave Brown push rods for elevator and rudder. I extended the wing tubes because they looked too short and a lot of work went into getting a good snug fit for the out wing panels on the wing tubes. In fact everything needed a lot of TLC to get it right.

Bottom line, it fly's well and looks good doing it.

Thanks to Andrew for replacing defective parts and going the extra mile to keep the customer happy.
