Which Edge 540?
My friend bought the AW 60/90 Edge and powered it with a YS .91. I flew this plane alot and although it was good, it was NOT great. It was HEAVY at over nine pounds - replace the gear and save more than a 1/4 lb I bet.
The plane was just NOT capable for the type of flight we like. He has sold it and won't buy another one. Cannot recommend
