RE: Building Ringmasters
Hi J-K, thanks for your inputs. The Enya is actually heavier than the OS FP, listed at 4+ oz. They used a rather thick cylinder sleeve with bypass ports cut in it. A modern .09 to .10 Schneurle would be definitely enough power for it. With inputs from others, I am gathering that the Enya is not as efficient as the OS FP. Reading reviews of it get the impression that one can go larger, wider or steeper pitch on the props and it will turn them. Out of curiosity I plan to test with a 9x4 prop, and picked up two 8x6 props to see if they will make a difference.
I am by no means a skilled stunt flier. Last time I flew was briefly in the 1990's, before that the 1970's, mostly half-A although I built and flew a Sterling S-2 Profile P-51 by Matt Kania with McCoy .19 Red Head briefly during the mid 1970's.
Here's a flight using the OS 15FP:
