Calling it the Edge44
This is just the Edge that Goofy designed shrunk down to a 44" span.

Here are the specs.

Span 44"
Lentgh 40"
Wieght 35oz or less
Wing area 453 sq in
motor 3542 900kv
ESC 50 amp
battery 2200mah 3S 30C lipo
Servos Tork 1811 on rons and solar D658 in the tail.
CG 4.25" from LE of root rib

So the build is pretty straight forward and on V2 I will document every step of the build. On to how it flys.
Its freaking sweet. harriers are nice and smooth and inverted is pretty well locked in in my opinion. Hoooovers awesome wants to torque roll. I think it could stand to have a little more aileron authority in a hover but there is plenty there when flying around. Elevator is more than effective was able to pretty much get it to rotate around the wing at WOT and full up elevator. KE I'm getting dialed in but it does it great. Very small amount of roll back to the belly and tending to want to pull to the canopy. A little on the nose heavy side at first but after cutting 1/4" off the nose so I could recess the motor all the way back and not need small standoffs that got better. Think it could stand to be a little further aft but I can play with the battery location some more. Rolls aren't quite axial. Have checked and I'm getting even travel up and down on both rons so I guess I will need to add a little differential into them.
I built this with a 1/4" fuse and carbon arrow shaft trying to keep the weight down trying to keep the wing loading down. After flying it I think the next one will get a 3/8" fuse and tube as the elevator is chasing the tail a bit in rolls.

Now for some videos

Maiden flight

Flight #2

Short inverted flight

I have one more video that is uploading now of it flying with the landing gear and repairs from the first dork it had.

Looks good Chris :rockon:
Thanks. You should build one. Fun little fucker to fly.
I bet, I certainly had fun with the original :rockoncool:
Just the fact that it will carry its energy well is what makes it so much fun.

Is it just me, or does nitro powered slabs look sexier when they are broken? Sorta like the difference between a war story about loosing your leg vs a paper cut scar from shopping at Victoria Secret.

There will prolly be a removable wing 20cc version later on. This one would be too difficult to make removable wing. Might be able to make the fuse break away right behind the wing though.

It's pretty easy to make most any fuse break away right behind the wing....just sayin

Took the JR out to play in the snow. Goofy dared to go try and drag the stab in the snow doing a low KE pass. I did my best.
