Welsh3D:
I assume you were very pleased with the 30cc engine.
I have the 1.4 RCS (Moki) on my Hanger 9 edge and it flies great but I would like to add a few more horsepower without going to a light 40.
Can you elaborate a bit on the flight performance with the 30.
Here is the RCS link, should be the same engine.
