Default O.S. 1.20 AX Specs

I am looking for specs including torque curve with output in order to build it for Realflight G3 and put it in a couple of planes I am planning to build. Why not build it first in simulation then for real once I get the bugs worked out.

The only specs we have are the following:

Displacement: 1.218 cu in (19.96cc)
Bore: 1.197" (30.4mm)
Stroke: 1.083" (27.5mm)
Practical RPM: 1,800 - 9,500
Power Output: 3.1ps/9000 RPM

We do not have torque/horsepower curves available. They are not provided by O.S.
