Hi Miloh,

Yes, it's true the Edge has a straight leading edge when the Extra doesn't. I reckon that's a big factor in an aircraft snapping, and that thought is backed up if you consider a CAP (which has a bigger sweep, and is a snappier plane) and a Giles (which has an even greater sweep, and is a snapping monster!).

Also, generally speaking, the thicker the wing, the slower is the stall speed, and Edges have fairly thin wings. Having said this, I am still amazed at how slow the VF Edge will fly before it starts to stall. It might be something to do with the solid surface of the wing keeping its aerofoil shape I suppose.

I have Extras as well, (Graupner and GP) and they do tend to snap more. I haven't yet built my VF 58" Extra, so I have that to look forward to!
