Thanks Guys, Yes that Gremlin had a Jett 35 on it at the time. I've sense taken it off because I don't think Gremlins are supposed to move that fast!! At the time I was exparimenting with different power-plants. Since then I've learned airplanes in combat aren't supposed to race away into the next county... I probably wouldn't find anybody to combat with over there. So, I've gone back to an O.S. 25. I can turn sharper corners if I go slower - and I can stay in the same universe as everybody else.
I will look at your suggested web site - thank you!!
I have some electric wings and have tried that hand-launch, from the wing-tip, ...doesn't work well or me. I've seen it done by others and I guess I'll have to practice the maneuver.
