We had a ball flying the Ringmaster Trainer IIE Saturday. My son used it to get some first flights teaching my 10 year old grandson to fly. He flew it 5 times with the only mishap a nose over take off. I set the Hubin FM9 to 1 minute flights at 10,500 rpm. I reduced it to 10,000 rpm after the first flight. It was a little too fast for a beginner. Then increased flight time to 2 minutes for the last flight. Came in a bit heavy at 40 oz. Part of that is a result of using aluminum landing gear from a Brodak 38 Special and 1.2 oz of wing weight. Set up is Arrowind 2815-09 / Castle Creations 50 Lite ESC / Hubin FM-9 timer / Nano Tech 2200 4S batteries / 9 x 6 EP prop / 60' .018 lines. I am going to change lines to .015 x 57' for the next foray. I flew it also it and it is a solid stable platform. Perfect for beginner trainer.
