I also have a couple of 'small' OS FX .46's in mine using MAS 10X7 3-blade props.
Spring air and Robart wheels.
About 25 flights (no single engines landings, yet!).
A 'heavy' flyer but like yours, does those loops.
Hanging up in the family room right now: that bright thing you have down there called a sun won't be in my part of the country for another 4 months.
The cowls have since been painted to match the rest of the plane(had to do the same with the nacelle covers).
