I think i finally cured my lust for a little more with this airplane... it flies and balanced just like with the os.91. knife enge, rolls like a dart, no stall on tightloops, inverted is perfect,BUT! thats where it ends. This baby's fast . Our field has a 500 ft runway and she uses every bit of it as slow as i can fly it.. not saying too much about it because it really sounds ridiculous. and i know the muffler LOOks ridiculous, its not taller then the profile of the cowl so it doesnt bother me a bit. super tigre 2300 inverted in front and 6V 5 cell giant battery a little back in fuse for balance. 8 flights with this setup and all is well. did a major reinforcing jobbefore hand as well. if youve got the room for it, i recommend it.. hope you get yours back flying again BUll
