RE: Edge 540 .40
Flies great, a little heavy at 6 pounds or 2.73 kilos but that's my only complaint. Flies precision and 3D pretty good. Knife edge flight is good. Needs an 82 or bigger 4-stroke, or 60 or bigger 2-stroke. I have a YS 63 in mine and it's great.
For starting 3D flight it's ok but a profile plane is better in my opinion.
