The Tower 75, and an OS91 fx weigh within an oz of each other, according to Tower's Website. I have done some lightning too. Removing the pilot, and canopy floor was worth almost 1.75 ozs, and removing some material from the tail fin fairing was worth just over .25 ozs. So those two together was worth 2 ozs so far. Still looking for more to remove, as I want this to be a 3D plane.


On a side note I really do appreciate some one measuring the wings for me! I went ahead and ordered one anyway but it would have been nice to know before making the purchase. I did measure mine, and came up with 831 sq inches of wing area in case anyone wants to know.
