If I recall, the RCM trainer is what Great Planes later kitted as their Trainer 20/40/60 series. What wonderful models! I have a couple of friends who each have one of the GP Trainer 40s. The roll rate is very impressive, and they're very fast! Probably far better sport planes than trainers, but they don't have any bad habits.

It's another kit that I wish GP would re-issue. I'd grab a Trainer 60 in a heartbeat.
