RE: New Decathlons From Seagull 91 and 120 Size!
I have the KMP Husky:
Wing Span.: 80in/2035mm
Wing Area.: 946sq in/61sq dm
Fuselage Length.: 53in/1350mm
Flying Weight.: 7-8 lbs.
Engine Spec.: .60 2 cycle or .91 4 cycle
Servo's Required.: 5 channels 8 servos
I have the OS 120 with the pump on it with a 15X7 3 blade and on floats and it is plenty of power.
I have almost unlimited vertical with floats on, and unlimited on wheels. Yea a 160 would be cool with smoke too. That's what I'd do with a Decathlon.
I live at 4500' and fly at about 5000' I think the 91 4 stroke would give you scale performance, and anything else, well, just more fun.
