A ROUGH equivalant for OUTRUNNER motors would be ABOUT 100 watts per pound. This will get you in the general ballpark.

If you have a 6 lb plane (average 40 size plane ) you would need a motor capable of handling 600 watts of power.

Of course, you have variables that can (and do ) radically modify this - is the battery capable of delivering 600 watts to the motor, the dia x pitch of the prop, the type of flying you intend to do, are you going to use a gearbox, etc, etc.

Your best bet would be to D/L MotoCalc (free to use for 30 days ) and plug the figures into that. MotoCalc will get you A LOT closer to a motor, gearbox (if needed ) and prop dia x pitch.

Try hobbylobby.com or call them and talk to L.A. Johnson.

Go to the "Glow to Electric Conversions" forum here in RCU.

There ARE "nitro" engines, that's what the car and boat buys call glow engines.

This chart works for me.

.20-size glow engine / 300w electric motor

(OS Max 0.20 engine develops 0.4 hp = 300 watts electric motor (AXI 2820))

.35-size glow engine / 500w electric motor

(Fox 0.35 stunt engine develops 0.7 hp = 522 watts electric motor) (AXI 2826)

.40-size glow engine develops 1.0 hp = 750 watts electric motor (AXI 2826 or 4120)

.60-size glow engine develops 1.3h.p = 975w electric motor (AXI 4120 or 4130)

.90-size glow engine develops 1.6h.p = 1200w electric motor (AXI 5320 or 4130)

1.20-size glow engine develops 3.0h.p = 2250w electric motor (AXI 5330)

DA-50 develops 5 hp = 3750w electric motor (AXI 5330)

DA-100 develops 9.8 hp = 7311w electric motor (Double AXI 5330)

^^
Just keep in mind that electric motors are usually high torque. A 745.7w (1bhp) electric motor would probably be closer to a .62cu size four stroke glow.
