Well, Im just using the bathroom scale, same one I weigh all my planes on and they seem to be in the ballpark.. It has CF gear and tailwheel and spinner, 2 2700 nimh's for the single rx, one more for the engine, one matchbox for the rudder, one servo per aileron instead of two, and all servo's are 8611's, no pilot, cut all foam out of canopy, aluminum stand offs, Am I sure about the scale no, has it been fairly close before? Yes! It cant be far from that number.
