In order. Fox 45 Ring, Super Tigre G51 Ring and MVVS .45 ABC.

All very reliable. The Fox isn't a startling powerhouse, but it has never quit on me in flight (except when it runs out of fuel) and always starts within 2 or 3 flicks, even after a time "on the shelf."

The ST and MVVS are similar in performance. Both transformed models previously powered by Asian BB.46's, from "OK" into "WOW."
