You have an 11x4 on a Saito 82? I hope you pressed the wrong key and you meant 14x4. I can imagine. Im am really not worried about power as this OS runs strong. We could hover and torque roll my dads Kadet Senior with it, and I know it was over 6 pounds. I am just worried about the extra 5 oz or so hurting the flying capabilities of the plane. Thanks for the input.
