Greetings,

I have a Hanger 9 40 size Ultra Stick with an O.S. 50 SX. I thought it would be fun to build a second one as an electric (that way I can share the wing). I have looked at the Hacker and Jeti Brushless motors.

I know this plane will take some weigt. I originally had a Saito 72 in it. I use it in the winter with DuBro skiis.

Does anyone have any recommendations on motor/ESC/battery setups?

Also, how would I mount the motor?

Thanks,

-Michael

First the weight of the plane is a big factor in determining the size motor. A brushless motor should take anything up into if you put a big enought battery that can dump enough amps to the motor.

Remember that the battery pack for a large plane adds sygnificant weight and needs to be taken into account.

If you know the horsepower of the .72 you can convert hp to watts. Then pick a motor, gearbox (if you need it for a larger prop) ESC and battery accordingly.

The Astro Flight Wattmeter might not be a good tool for you since you don't have a motor and prop to test. I suggest using MotorCalc (www.motocalc.com/index.html ) to get a general idea of what you are looking for.

A fellow club member built a US electric. He used a Hacker b50 with 24 NiMh cells. Vertical out of sight. Hover. 3D.

Go for it. If you can aford it. Peformance costs money.

Twins are the reason, for the joy in the season.
