I don't want to insult you but you are the first of many that has had this problem are you sure maybe take it apart let it and set for a day then go back to it. I say take it apart to reduce or remove the stress from the plane

1 1/2"? Something simply cannot be right. I have 2 of these planes and nothing is even close to that far off. Do recheck everything, and post pics if need be.

Agreed Ken. That's probably a good idea.

I just disassembled one side but after sitting for 5 days there wasn't much spring back so they looked much better than they did before assembly. I'm not insulted that you guys are questioning my assembly skills or techniques. But after spending the last 25 years working in the dimensional control field, this kind of stuff drives me nuts. Even the distance between the holes on the plastic mounts isn't the same as the holes on the z brackets. It just isn't that difficult. Or maybe it is...

Again not hurt your feelings but they are called "N" struts

I really don't think I did anything wrong. I followed all the suggestions I found here and my plane looks just like all the pictures I see here. Maybe I had a set of warped wings or something. If this plane flies like I hope it does, I won't give a fat rat's fuzzy butt how it went together. Now it's just waiting for the weather...

Darn I getting ready to order a second one and now it looks like there may be quality control issues now. Mine had no issues at all went together very nicely only mod I did was tap plastic to use 3mm button head screws and no nuts.
If you bought through Grayson they will help you out Nitro you are on your own.

This one an their Pitts are my favorite planes, building their Tiger Moth now.

If you look closely at the picture of the N struts you will see a flat edge on the ends, that side goes to the top wing. The ends that are rounded mount to the bottom wing. If yours are mounted that way and you are having to twist the wing then I woud get some new struts from the seller. http://www.nitroplanes.com/60p-wako-09-wingstruts.html

DejaD, pics of the install maybe?
Could be time to send a portion of the model back and get a replacement...that's a lot of inaccuracy!

Just for reference, most everyone in the biplane world calls the outer struts on the wing N struts, and the inner struts cabane struts.
The problem with calling them N struts are that sometimes they're not arranged in the same N configuration, sometimes they're backwards from the same point of view.
Another problem is that not all biplanes use the N configuration, some of them don't have the middle strut making it an N shape, some have cross braces between them in an X shape, and others use a single strut (like a Pitts).
Technically the term for the outer struts are interplane struts, because they tie the two wing planes together.
Cabane struts are the correct technical term for the inner struts attaching wings to fuselage.
However, since we're dealing with a tiny scale version of the real thing, I believe the term Z bracket is somehow fitting...though I sincerely hope my N struts don't turn into Z brackets on landing

I will have to take a look for the flat spot and see how I mounted it. Thanks for the support, fellas. I really appreciate it.

No need to worry Tim. Order it, as I'm sure it will go together fine just like all the others have. I really doubt there is any quality control issues. I'm sure Deja will get his figured out.

Hey Deja...check out my post about this issue at #610. Not as severe as yours, but this was my fix. Changing the plastic brackets to plywood was a great choice for me. Good luck.

I wanted to post some photos both of my planes are setup in this way
