Hi guys.

A fellow flyer has just rebuilt this plane after a mishap on its maiden.It is running a saito 180 4s and it flys realy nice,motor needs some more running in but the problem is when he does loops it tends to roll out of them when he passes the top section of the loop.It will roll out till it is flying straight and level again.

It cant be snapping surely at slow speeds? As it flys realy well at slow speeds with out a wing tip stalling at level flight.

It does drop a wing if too much elevator is used like in most of the posts on here about the 540 but this is not realy a stall but more of a roll as the end of the loop is done.

It makes this pilot not realy confident to get it down as it might roll at the wrong time again and go in..

Anyone have the same problem with the Hanger 9 edge? Not many posts on here saying this plane is very good? Plz share your thoughts,as this friend realy likes this plane.

First thing to check would be to make sure both elevator halfs are moving in unison though there travel up and down.

Yes, it can be a snap at low speeds. If you have too much elevator it will snap and what you describe is typical of how my CAP 232 behaves.

You can tell if it's a snap by using less elevator in the roll, if it behaves better then you have the problem identified. You then setup your low rates so that it doesn't snap with full stick deflection, high rates are whatever you want.

As the other poster said, you can make sure both halves move the same amount, if so then the thing is snapping.

Thanks guys ill get him to check the elevators but i think they are right.

Also his wing is dodgy as when you look at it from the tips(right wing) the the botom of the wing is symetrical but the top is nearly flat,its like they built it upside down.

He has tryed taping some card board to the bad wing to ROUND it some more and this helped a little bit but it still has the roll on loops.With out the card board it would roll coming near the top of the loop,not on the down side.

One more thing to check is if a wing is twisted up at the tip. This creates "wash-in" which makes that wing extremely prone to tip stalling.

I had that problem with my first YAI Edge 540 wing. If you had enough elevator control to land the plane, you had enough to cause a snap - and always in the same direction. Landings were really hair-raising events. I finally tracked it down to the wing twist. The replacement wing is straight and it is a completely different plane to fly. No snapping out at all with normal deflections.
