RE: Vectorflight Edge 540 build
You don't want to know!
I went and ordered 2 Edge 540's, 66". $149 + shipping each. Good price for a quality unit. But I am all out of engines. Might have to wait till I plant one. But I do have a 4* 60 with a TT 90 FS in it that is about due to be retired. It has had a long hard life, but still going. Maybe an excuse for a new engine.
