Let us know how you like the BL 46 performance. Thanks for the balance info too.

If you want to use the original warped wing, you may try to unwarp it with an iron set on low. (use a nice cotton under shirt over the iron to avoid scratches, or buy a monokote iron with the little "sock" on it). I have warped wings to put in wash out this way. Very easy.

There was a post earlier that said the good balance point is when the nose is about 5 deg down when balanced on the cg ref in the manual.
