I just built my first plane.It's a Sturdy Birdy II w/ ailerons and an OS 40.I have not flown it yet,but I think I may have put too much dihedrahl in the wing,what will happen if there is too much?also 1 wing tip is lower than the other,I can shim it but I'm wondering if I should just saw it in half and start over.Any help will be greatly appreciated.
Thanks,

What do you call too much ? Can you measure the heigth of one
tip when the other half is flat on the table ?

1/16 of an Inch less than 5 inches.With 52 1/2 in. wing span.

That is a little much, but you won't have any problems once in the
air. It will be very stable in low wind. The ground handling will be
tricky if there is much side wind wanting to lift one side and tip the
plane over moreso than a flatter wing.
I don't believe it is worth the time to try to cut and reglue. I did
the same thing on one of my first planes when I put the 2" block
under each tip instead of just one to set the dihedral.
The turns in the air will be more flat using the ailerons, but it will
turn nicely using rudder only.

Hello,
Cool,I'll try it out first then.I'll have an instructor w/ a buddy box so it should be OK.Thanks for your help.

The only problem with too much di, is that you can't fly inverted. Other than that, enjoy!

If you have too much dihedral, it will make the rudder very sensitive. Since you have ailerons, it will be no big deal. Fly it and see, you should be fine.

A fellow visited our club with a rud/elev/throt type of plane. He had built it out of plastic sign material and a piece of PVC downspout material. He put 10in of dihedral in it when it called for 5in. Thought it would be more stable that way. I flew it for him since he was learning. It flew fine. Took off fine and turned OK. It was a plane called a SPAD. Cost him $20 to build. Be good for a first plane. Just about indestructable. Used two yardsticks glued together for a spar. His son laid the wing on the ground and stood on it then we flew it!! I believe the website is www.spadtothebone.com.

Thanks guy's.

Hello all,
OK I finally got to fly my plane.Actually I had a friend fly it and it flew great.
No problem w/ the dihedrahl.
Thanks,

Good Job,
The only problem you will have is it will be harder (no impossible) to fly inverted.

I think once I get used to flying I'm gonna buy another wing and put little or no dihedrahl in it.I might try a Dura-bat wing also.

Geistware is correct, the only problem will be with inverted flight in the air, on the ground it will tend to tip easier in cross-wind. I don't recomend another wing, when your ready to move up get an aerobatic trainer.
