I just put together a Global Freestyle w/ a Magnum 52 XLS 2-stroke using a 12.25x3.75 prop.
It seems to have plenty of power and good vertical performance.
The Global Freestyle seems to be of the same size/weight as the U-can-do 46, so it should perform well with that engine, right?
I was also thinking of the Evolution 61 2-stroke, any thoughts?

A 2-stroke for me might be a better option for the u-can-do 46, since after reading these posts it seems like you have to put a $200+ 4-stroke to get the performance the plane was designed to do.

I am all ears
