Default Flash first flight

Here's some pictures of my Flash's first flight (thanks Marty!). I had air problems and couldn't retract the gear on that flight. I got those fixed and was able to put them up on the next two.

I really like the looks of this plane in the air. I was very worried that it would be hard to see, but with my paint scheme, it was very visable both against blue sky, and against overcast.

As far as the flying is concerned, it was good, but I have a few issues to work out. The first was that the stock aileron sensitivity with the flaps up as too high (I set the rates up to correspond to flap setting as per the manual). That was easily fixed. I kept the higher rates on half-flaps and full-flaps but raised the expo.

It required too much forward pressure in inverted flight, so I need to remove some nose weight. I simply taped lead shot to the front of the main airbottle in the nose, so that is easily done. I also noticed a pretty good pitch-down with flaps which surprised me. I did not put in any elevator-flap mix as per the manual.

I also noted a pretty good nose-up pitch with power. When I trimmed it for level flight at full power, it would require a significant amount of back pressure for level flight at half-throttle. Has anybody noticed this? It is very prevalent with full flaps. When I roll level on final and chop the power, the nose drops big-time - requiring an immediate hard pull to avoid pancaking into the ground. I may experiment with a bit of a throttle-elevator mix, especially at full flaps, to help counteract this.

I flew quite a few laps at full power with the P-120. The airplane definately scoots at full power, but its very managable. The P-120 is plenty of power for this airplane, but its not too much as some folks have told me. I think its a perfect match for the Flash.
