Can those of you who have a H9 edge 540
let me know any problems that you have come
across. I believe that there were some
wing problems initially.
Thinking of powering it with an OS BGX1.

Any comments will be appreciated.

I have one and they are a great plane. I was unsure of my wing, I had an early kit so I took the covering off the bottom and thin CA'd everything. I also added verticle shear webs to the back side of my spars. My wing had a forward sweep, but that wasn't any problem to sand out at the root. I also fiberglassed the center section for a little more strength. I have flown it about 7 times now, and have done two full power blenders that were just horrifying to watch. I knew the wing would fold but it didn't. No damage what so ever except I burnt an elevator servo up. The stab on mine would not line up with the wing and the incidence was way out of alignment. So If you build one of these make sure you use an incidence meter to get everything lined up. The filler blocks around the verticle stab had a very poor fit as well. I cussed this airplane going together, but after flying it, all that work was worthwhile! This is a great flying plane. Flies real nuetral, and doesn't seem to have any bad habits. It is also a joy to land. All up weight wasn't that bad either. If get my muffler, and my servo in maybe I can fly her some more. I used two high torque servos on the elevator, and all other surfaces were high torque as well. Power is a saito 180 with a 17-6 apc. I didn't like the 16-8 the manual recomends. Not much left for the pull out of a hover. If you have had some arf building experience go for it. They are a fun plane to fly. The newer kits may not have near the number of problems mine had but I would still check the stab incidence very carefully before glueing anything. Happy flying.

capthis - Do you know where you have your H9 Edge CG at. Mine is at the min 4 1/2" and seems to be unstable at times.

4 1/2 inches and I am going to try to ease it back from there a little at a time. My friend (lovemyedge) has the lanier edge and he says his is just over five inches, and is still very stable. So I think the 4 1/2 is conservative. A heavy plane will fly poorly and act unstable, they like to snap easier. So see if you have any weight you can remove. Also did you balance yours upside down? I did, and I think thats how you are supposed to do it. I have had several "scale" areobats and have always balanced upside down. I don't know how much experience you have with these planes but they do not have the flying characteristics of many sport planes. They just aren't as forgiving. Hope this helps. Happy flying
