2 points, which you may have already tried or thought about:

- Exercise the joint, bending the elevon back and forth several times to loosen the hinge. Make sure there is nothing stuck in the crack, like a booger from the hot-wire cutting.

- Make the arm on the servo as short as possible, to use the maximum throw, rather than turning the endpoints down. This will give you the maximum available torque. On the HXT90's, I'm a hole in from the end on the single arm IIRC.

Yeah, moving the surfaces works but takes work. Leaving them bent out like that over night is amazing. Now they feel like tape hinges. hehe.

Im pressing them now. Got the plane upside down with the flaps bent underneath and a phone book on top. If that doesnt work, I might still cut them and tape them.

Now I have conflicting advice. When I finish pressing the flaps Ill see how they move with the long horns and arms. Then Ill compare with the short arms and horns. I WILL get this bugger to work.

Right on. I didn't put anything on top. Not sure if that would stretch them too much or not.. If anything, flip it the other way the next night. But I don't think I need to do that just after the first time.

Folding them under made a huge difference. Now all thats left is to get my throws right.

Did anyone have to modify the method for attaching the motor mount to the wing? I saw in the op that he cut a notch in teh wing, but I dont want to have to do that. I might drill little holes through the mount and the plane and attach it with bolts or zip ties. Any advice on this?

Thanks for the help, fellas. I really appreciate it.

I don't think that bolts and zip ties are really required.. I just glued mine on and have never had an issue about it wanting to come back off.. even on rough landings there isn't any stress marks on the foam. I did cut the bottom supports so that I could slide my mount forward but did not cut any of the foam to do that...

Let me know if you need a visual, I can post pics if that would help...

Why are you modding the motor mount?

Diggs

I think I understand, but if you dont mind, pics would be appreciated. What did you use to glue it: CA, super glue (thats pretty much CA, right?) hot glue, two part epoxy, etc?

I use goop. And some CA for the initial hold (so the goop dries). kinda mixed together.
I did trim the bottom notches to be able to move it up a bit as well.
yeah cA= super glue.

It was easier to cut the bottom of the mount and slide it in while working on getting the CG correct... may notbe the right way but it works well for me..

Here are my pics... I did use UHU to hold it permanently and CA just to tack it into place..

Oh!. Glad you posted them, because I thought you had trimmed off the other side.

Whats UHU? And is your ESC packed into the motor mount too? Thats a good idea.

Glad that my pics are better than my descriptions... =)

UHU is like Goop... like a contact cement that doesnt eat foam

Thanks! Thats last piece of my puzzle. Now I just have to sit down and get it done.

The help was invaluable. Ill try to get someone to film me flying it for a minute and let you guys see how it turns out.

Get shoe goo at wallmart.

I wish I didn't shave off the bottom part of the mount now.. with the motor in the inside of the mount and a shaved bottom.. I don't think I can fit an 8in prop..
