Another gas powered Decathlon was offered up to the flying gods yesterday, and arriving back home on terra firma safely, despite very windy conditions! Thankfully they were blowing right down the runway. There was enough wind on a couple of landings to permit a 20-30 foot roll out! The RCGF 20 was proven to have plenty of power, offering unlimited vertical, though maybe not enough for all out 3D. Using an APC 17x6, but not tached yet. Plenty of ground clearance. The engine was very easily dialed in and the second tank of fuel was spent in the air. Suggested CG has proven fine, maybe a hair nose heavy. Suggested aileron throws for low rate not quite enough for me, but fine for the test flights. Knife edge coupling, holy cow, had forgotten how bad they really are. Going to take while to figure out all of what needs to be done there! 4 tanks of fuel with it has let me do a little engine tweaking, a little fiddling with the radio, and the plane is already settling down into what I think is going to be a great little flyer. Very happy with the plane overall. -Al
