A Little Help Please with Motor Selection on Ultrafly Biplane
I have an Ultrafly Biplane and would like to know, will the following motor do the job?
Max Current (Full Loaded) 18A
Voltage 6-12V lipo battery (2-3 cells)
Weight 40G
Internal resistance 150 Ohms
KV ( RPM) 850
Propellor 9x 4.5 to 10 x 5
Recommended ESC 25A to 40A
The specs of the biplane call for a 150-200w motor, but I have no idea how to extract the watts from the description of the motor above.
Wingspan: 35.4" (900mm)
Wing Area: 458sq in (29.7sq dm)
Weight: 20-25 oz (570-700g) ready to fly
Airfoil: Fully symmetrical Length: 37.4" (950mm)
Motor: 150-200 watt capable motor
Requires:
Radio: 4-8 channel with micro receiver
Servos: 4 micro size
Battery: 10 cell nimh or 3 cell Lithium
Electronic Speed control: 25amp recommended
Many thanks!
Rob
