Decided on the 120AX. The smoke was not for this plane actually. I just got for another plane and thought of using it on the leo cause of the extra space I would have. I very new to pattern flying and learning alot form other threads and realised its not a good idea to add more weight. I just got myself a perry pump and now hunting for a header and a tune pipe that would fit the 120AX.

Any idea what a good size prop should I use?
