I havnt seen any thrust numbers on the 91 but a lot of poeple dont like it. They say its not what its supposta be.
[email protected] running a os 50sx. BUT...I changed the wood in the wing and lost a LOT of wieght. Allso will be carving out the fuse and changing some wood to lose sommore. I think i will put some carbon in the tail. Maybe some wires too. Your rudder and mine are the same thing but i moved the hinge line 1/2 inch. I didnt add any width to the elevator though. I thought 22 inchs was enough. hehe.Also cut a 45 deg angle on the elevator for the rudder. you need to wiegh that thing. The lowest ive seen is 5.5. mine should be in the 4.5 to 5 lbs range. I hope.
