Pat Tritle / Manzano Laser 44" DeHavilland Tiger Moth

Raible Recipe

Performance:
Wing span = 44 inches
Wing area = 570 square inches (3.96 square feet)
AUW = 26.2 ounces (1.64 lb)
Wing loading = 6.62 ounces / square foot
Landing at 16 minutes w/ 3.8 V remaining per cell
Cruise at 2/3 stick (measured)
4,050 RPM
3.68 A
29 W
Takeoff full throttle (measured)
5,470 RPM
8.7 A
69 W

Analysis:
8.4 V battery x 920 RPM/V motor = 7728 RPM propeller nominal / theoretical
8.4 V battery x 22 A ESC = 184.8 watts maximum capable
using 11 x 5.5 prop; 69 W / 1.64 lb = 42 W/lb actual
5,470 RPM x 5.5 prop pitch x 60/63360 (inch/min -> mph) = 28.5 mph max pitch speed
3.7 x sqrt (6.62 ounces per square foot wing loading) = 9.52 mph stall speed

Hardware:
