Default RE: Vectorflight Edge 540 build

Wow! There actually is an end to this thread! Sorry to mess it up with another post. I finished an Edge a few weeks ago but was off to the airshow at Oshkosh with my 100% scale Ercoupe so did not get to do anything but a Maiden flight til last weekend. I got to really wring it out then.

My kit has the new fuselage / wing attachment and it works very well. If you are not familiar with it, there is a recess in the fuselage about 1/8 inch deep and the wing root seats into it on each side. There is an alignment dowel about 3/4 cord aft in the wing that passes thru the fuselage and into each wing. The center section of the main spar now attaches with a single bolt. I read in earlier posts some time back about concern with the wing seating at the aft edge of the wing. There is none of this with the new update. It is very simple and rock solid. VF suggested splitting the dowel and doing the same thing that Sig does with the Something Extra with the rubber band to keep things seated, but I could not see the big deal with just leaving the dowel in. Works great. No working of the wing whatsoever.

I used a carbon fiber arrow shaft for the dowel at the front of the belly pan and two small screws at the back. Simple and fool proof and light.

Mine is powered with a Super Tigre .90, same power I used in my 58" VectorFlight Extra. Right now I am turning a MAS 13X6 Semitar prop around 9800 rpm. Verticle is superb, power very good. I'm planning on moving the rpm up to max power this weekend, probably another 7 to 800 rpm in there. My experience is that 10K seems to be the point that APC props start to perform better on these motors, so I'll also try that this weekend. In the past under 10K the APC does not have the pulling authority of the MAS Semitar. ST's have alot of torque and I have always run a tad rich, but this year I'm moving up rpm and likeing the results. Like most of you, I'm adicted to VF's stuff. Nothing flies like em. I was suprised to see the Edge flies even better than the 58 in Extra with the same power. Keep the word going among your friends and clubs about VF. We need to support north american companies, there aren't many left and we don't want to loose this kind of quality and customer support.
