Well all I can say is what the scale tells me and it seems to pretty accurate--remember planes do vary in weight from plane to plane and mine has more or less been sitting in an oven ( my workshop ) for several months so it's pretty well dehydrated----19 lbs will definitely be attainable with a carbon spinner--no wheelpants for me as I don't like the big holes they punch in the wings when the gear come off--I considered the Evolution 58 but it seems they are having problems with engine rings and the Super 80 is only about 5-6 oz more--it really wont matter if it flies good--I have a Hangar 9 Extra 260 with a DA 50 and almost everyone says the wingloading is too high ( 29 oz/ sq ft ) but the plane doesn't care--I've harriered it down the field at 60-75 degrees with the wings rocking like monkeys on a trapeze and it is yet to snap--I'm just hoping this plane flies as nice as that one
