Drew,
C of G is definitely within limits, just a little towards the back of the envelope.
Waiter,
Thanks again for your advice. The ailerons were hanging roughly a 1/4" with the play taken up. I think thats most likely my problem. I won't have a chance to fly it till the longer loom for my new EDM 700 gets over here and I have that fitted, hopefully next week. I've got my fingers crossed that I'll pick up a few knots also. Aileron acting like flap must create some drag as well right?
I'll let you know when I have a chance to test it:)
