RE: Jet Edge 540 Chief aircraft
It's the same one that Giant Scale Planes and several other direct importers sell. It has been around for a number of years and does not have a good reputation for quality or flight performance.
As for a gas engine, why put an expensive engine on a low end airplane. You'd have to beef up the firewall and the extra engine and balance weight would just make the tip stall problem worse.
There are much better airplanes available.
