I'd say it's the difference between a "first flight" beginner and a "Getting the Hang of it Learning Flyer." Also maybe the number and skill of the flyers trying to teach.
The Jr. Ringmaster gets to be hard to handle up around 45 deg. The Jr. Flying Clown probably(I've never flown one) will handle more aggressive handling, more wind, and is good enough to fly all the maneuvers.
Let us know how the flights go soon!
