Hi Mike,
Thus far as you see the aircraft plus the fan, servos retracts, wheels, tanks etc... the all up weight is 11.5lbs, there is really no weight to the fuselage at all everything I have done to this aircraft is basically, carbon fibre strengthened skin of 3mm Balsa, the wings contain most of the weight. I expect the aircraft to be below 17lbs once all together. The Horizontal stab should help out slightly, as I am testing my luck as the fullsize has a inverted cross section. Your Fuz looks a lot more roomy then mine I am guessing, this is because the older version was a shorter wingspan, this is a TR-1 or U-2R version.

Is there anyone building U-2 from Scratch that has a plan in any CAD format? I would
Regards
Sean
