First, I don't want a "go buy a SD, Aeroworks, etc. Yak instead" thread. Please.

We're all aquainted with those fine Yaks.

I'm looking for info on the RichModel 50cc Yak.

I know a guy who is happy with his RM Yak and another who just got one and said it dry fit very well. They can be had for about $430-500 NIB so I'm trying to build up some info on firsthand experience with them. If you have one or have flown one, what was your impression? Stuff like AUW with set-up, slow speed and stall characteristics, overall flying ability would be perfect. Thanks in advance.
