RE: <span class=
Would it run OK on higher nirto fuel, I keep alot of Coolpower 30% heli fuel on hand and like to use it in my airplanes also. I'm planing on building a 40 size 3D plane soon and was looking at the MVVS .49 but don't like the fact I would have to use 5% fuel. Does this engine have quick throttle response for use in 3D flying.
