RE: Need help with wing set for alpha trainer
I finished putting my daughter's Alpha 40 through it's paces last weekend.
It had the offset servo, and I really could not notice it.
The maximum movement of the ailerons is so low, that you will not have problems with the linkage that way.
I also did exactly as Mr67Stang mentioned in his post.
After it dried I then applied the included tape for completeness.
I would also add that if you are going to use the rubber bands, that you may want to get some "saddle tape" for the wing roots to avoid damaging the wing.
