Hi everyone:

Today I took this engine finally in its plane and took it to the filed.

But I noticed that pushing a Master Airscrew 18x6 it had no power!!!

It struggles to pull the Funtana 90.

I read some people here are using 16x8 or 16x10.

How did you guys make the 3 small holes to hold the prop..

Since I have both of these props and the 3 small holes are practically outside of the prop center thus making them useless and dangerous.

I want this engine for 3D.. anyone know the right prop for this engine?
