RE: PT40 dihedral
I started flying last year - believe me it is much easier to control 4 channels rather than 3. The A wing is just too much in my opinion, even the sport wing has a pretty big dihedral in it.
It is very easy to do the conversion, especially if you have not yet covered the wing. If you have covered, you will need to do some cutting, but no big deal, You are looking at less than an hour's work to get it done. Buy a small amount of Basswood - 1/4 X 1/2 inch stock will do just fine, build a little box with two servo mount rails, use Epoxy. Then get a Y Harness, you may have to cut the ribs a bit to get the harness through. It is really very easy to get done. These planes are pretty tough, you can do some mods to them with out doing any harm at all.
BTW - got your PM and replied, will look into the cost of shipping the wing to you.
