Help with Hangar9 Edge 540
I've had my edge for about two years.
I fly mine with a Moki 1.80 and personally believe this is a good combination because for the size and weight of the airplane.
The only thing that really bothered me about the design was the wooden elevator push rod with a wire Y at the tail. I felt a plane this size with this 3D performance envelope would have been better served with strong servos mounted in the tail. So that's what I did and I've been quite pleased ever since. Its an easy mod and I'm certain when I hit 3D elevators in a blender I'm getting equal and solid throws. I did not modify my wing and have been performing the wall and blenders like a champ.
Regarding the flying: In the rear of the manual is a write-up my Mike McConville which is terrific. Essentially I followed his advise to the tee and have been rewarded with performing Elevators, Harriers, Walls, and blenders like never before. I must say that the elevator and harrier are so easy with this plane it's scary. Just make sure you add some spoilerons. You will need these to minimize/elliminate wing rock.
The only other problem I had was during landing on our short field. When I was running a 18X10 prop I just couldn't slow the plane down on calm days. I switched to the 20x8 and now I land with a tad bit of throttle at roughly 1900 rpms on the Moki.
Oh one other problem i forgot about./ Keep an eye on the hinges I've had a few break which I luckily caught due to my habit of checking the control surfaces after every flight. At this time I have robart hinges on both elevators and ailerons. This occurred on another 3D capable plane of mine and I think it is due to the large control surface throws required for 3D. So either replace them from the beginning or keep an eye on them.
