YELLOW AIRCRAFT F18 SINGLE CONVERSION TO TWIN MIDI FAN EDF
I had a good friend(fellow glow Fan flyer) do the first flights for me. This picture is from the second flight. First flights were done with (2)18 cell packs to keep the wieght at 12.52 pounds . I think the plane needs 20-22 cell packs. But I wanted to get used to using the flaps for landings and take offs before I bumped the wing loading up more. Used every bit of runway on first take offs, to make sure we had enough airspeed before rotation. First flight was a yawner, gradual climb, trim adjustments, and 2 oval circuits, figure 8 circuit, two practice landing runs, landing. Second flight was a little better, rolls are very axial. Had to cut the throttle down on one pass due to minor rudder flutter. Plane came in a little hot on landing approach. Oops ran all the way down the runway and off into the sage brush. I can't wait to try the flaps, need to slow the landing speed down a little. I could not get my friend to hand me the transmitter on the 2nd flight, he was having too much fun (that says alot when a glow fan flyer won't hand you the transmiter on an EDF plane). Flight times were limited to 4 minutes on purpose.
