Yesterday we finally had a break in the weather. Or rather, I found a 
daring confident safety pilot.

I can report, this airframe flies without significant modification. In 
fact it flies like on rails. I don't even think there is any tuning 
required whatsoever.

The only issue was a very short flight time. Mostly because cruise speed 
was very high. And I think my powertrain is not very optimal. I run a 
very high KV motor, but I could still give it a bit bigger prop I think.

I'm so chuffed.
