RE: Another Skymaster Viper
I just had the parts on a weight:
Fuse: 13.3 Kg (incl UAT, 125 mL)
Hor stabilizer: 0.8 Kg
Right wing: 2.5 Kg
Left wing: 2.5 Kg
Wingtube: 0.3 Kg
2 x Pilot/"bathtub": 0.8 Kg
Total dry weight: 20.2 Kg
add 4.2 ltr fuel, weight 3.4 Kg
Total AUW is 23,5 Kg (approx 52 lbs)
This gives me 1:1 in thrust/weight right from takeoff, nice!
