Hi Dave,

I sold my YS140 two years ago because it costs too much to fire it frequently, say 10 flights per week. I am flying IMAC with a 50cc gas motor now.

Another piece of news. ZDZ is preparing the introduction of the 40CC F3A gas engine in US by the end of this year (source: RCShowcase). Maybe YS is aware of this and preparing an answer?
