Finished.

Painted, decorated, balanced, propped (at 29 amps draw on a 3-cell lipo battery), and throws adjusted.

Ready for dry weather.

I was unable to do a reasonably good job with the wheel covers. I might try again at a later date if the plane flies well.

OK, here's the details of the first flight.

It flew nicely, but .... it took a lot of right rudder to take off (to fight the propeller torque); it was very under-powered; thus needing full throttle for decent flight; thus getting everything too hot, thus causing the power to shut off; necessitating a dead-stick landing (which was smooth and successful).

Here's what I did.

I switched from a 3-cell battery, 40 amp speed control and a 480-size motor, to a 4-cell battery, 60 amp speed control, and a 25-size motor. I opened up the air inlet (just a bit) below the spinner, added small air-flow exit holes on the fuselage sides sides behind the dummy engine exhausts, and put in a proper battery tray.

I have since flown it in cold and windy conditions, and it flew faster and much better. It really slowed down nicely for landing.

I don't need full throttle, and everything was cool after landing.
