I started this project on Monday September 20th. First test fit all components. Tighten the covering, cut all openings for stabilizer. I used Du-bro nylon hinges #117 for flaps and for elevator. I used CA hinges only on adjustable rudder. I replaced the kit flap wire jointer  with .093 in music wire. Flaps installed on Monday.

On Tuesday I glued hinges and the jointer in the elevator and stabilizer. I replaced kit jointer wire with 3/32 (.093) inches music wire.

Jerr-O,

I have seen those fly really well! I hope you are pleased with it!

Thanks, Dave!

Thursday was just assembly of everything)). I used one single piece of 2mm (.079 inches) music wire to connect flap and elevator control horn. O, I forgot, I reinforced the belcrank plywood bracket with balsa sticks and epoxy between wing sheeting and ribs. I saw the belcrank being pulled out before.
It is better to use offset control horn on the flap. But I used one from the kit and bent the push rod wire to clear the flap in the “flap up “ position.

Thursday 4 o’clock PM I was at the field to break in the engine and to do the maiden flight. CG was in the recommended position without any lead. Tip weight as recommended- 1 1/2 oz. First flight was regular settings on the tank, as recommended. Now I use muffler pressure for more consistent engine run. Line length 60 ft, lap time 4.9 seconds now, handle spacing is 3 3/4 inches. It’s a bit tail heavy in the end of flight on empty tank. Even with line spacing 3 3/4 inches  sometimes I over control this P - 40 on landings. But it makes corners easy.

In Cleveland Area Stunt Championship on Saturday September 25 my P-40 flew to the 3rd place. In ARF/ARC category. It was its 6th and 7th flight since maiden, flew tail heavy, not properly trimmed yet)). Engine is still under work to performance.
As glow version this model flies great, it goes where you control it. I did not see any vertical CG problem, as described by some pilots who flew it as electric.
For now I will try aluminum spinner to shift the horizontal CG forward.

Jerry

Motorman,
Thank you!
P-40 weight 51.5 oz dry. Tanager is my brothers work horse. He flew it in profile and in intermediate category. Tanager weight is 47 oz dry. Both models have OS .40 FP engines  and APC 10x6 props. In windy conditions they performed well.

Jerry

From my experience ( both with the P-40 and the OS 40FP),  the FP will be much happier with something more like an 11x4.5, it likes to turn rpms, running it 4-2-4 is not generally going to give you consistant runs, nor will the engine be happy

Thanks, Dave!

Hi Jerry,

How did you bend (90 degree) the pushrod from belcrank to the flap control horn?
Did you just use pliers? Or did you use some other tools?
