"Nose to tail small differences. FX3s weight in the mid 1100 lbs. The fuselage is lighter because of tube sizes and the top longeron concept, wings are lighter, ailerons and flaps are lighter, carbon fiber cowl is way lighter as is the oil cooler, baffles, torque tube, sticks, brake cylinders, plastic fuel lines etc. It is all a compromise. Some of those compromises didn't work out like using light fabric. I have maintained some SS Carbon Cubs and currently maintain a few EX/FX2s and several FX3s. Have a groundlopped FX3 in the shop now, changed the wing, gear and elevator. The performance and the control harmony in the EX/FX2 and 3 is amazing to me. I really like the perfomance and the ailerons. Not selling my Super Cub, house and hangar so I can buy one but glad there are people with that kind of disposable income.

To each his own. If you're fortunate enough to have one, bully for you! Party on and fly it like you stole it
