Well....I cant help you alot,but I can maybe give you some to think about. I have a PT-40 and built it with ailerons and the option B sport wing. I really never needed the "recovery" features of this plane as I was always on a cord for my training days and I never really had the plane get too far out of control. And just from flying it,I never noticed any "recovery" habits of the plane. Maybe its the sport wing,but the only thing going to "recover" my plane if I screw up is me! If I let go of the sticks.....I'm gonna crash,lol. But thats ok,because I never needed it,and to be honest I dont think I would want it. If your gonna crash its most likely gonna be while your flying low or landing or something,and it will be too late for the plane to recover itself anyway.

Now as far as that dehidral goes......like I said,I built the sport wing and even the sport wing has alot of dehedral. And the only dang thing that dehidral seems to do is make flying it in the wind a hen of alot harder because wind and dehedral hate each other. I'll give you a pic of my plane,it might give you an idea of what the sport wing looks like. If you'd like a better straight-on picture of it,just ask.....I'll go out and snap one for you right now. My point is........I would generally not recommend the option A Trainer wing because I believe it would just be too much dehedral. BUUUTTTT,I've never flown a plane without ailerons. So that will likely have a BIG affect of weather or not you should need the extra dehedral. Hopefully after reading our posts,someone of more experience can give you some better advice.

You may also want to consider adding the ailerons too,especially if you end up splitting your wing anyway.

Just be very careful flying your new PT in the wind. Even to this day I dont fly mine in the wind because its just a bugger to land. With that dehedral plus a totally flat bottom wing.........it can be challenging it even slight wind. But I still do love flying it about once a month. With low wind,its a pleasure to fly and land.
