I am expecting the Geared Endoplasma to run at 33 amps at 12 volts that is 396 watts per motor 792 watts total. The running voltage is more likely to be about 10 volts for 330 watts per side 660 total. Both are theoretically enough to fly the plane. The Endoplasma motor costs $20 and the Great Planes GD-600 gear box $13. The gear box is modified to 5:1 with a $4 gear from Gary Wright Model Products http://www.gwmp.net/

Several experts have recommended the Geared Astro 05 or 25 but at $130+ each I will try the Endoplasma. If worse comes to worse I have two small glow planes the Endos will fly for sure.

The photo shows the Endo mated with the gear box. The cooling fins are my idea and have yet to be proven. The fin must be drilled to match the cooling air vents on the motor.
