Hi Matt......I always read your stuff so I am familiar what your preferences are.....sounds like a good use for those Griffins.
Whatever happed to the Syssa deal?
From some of your posts and other info I read indicated that it was a good handling engine purposefully designed for model airplanes but needed more development due to being a bit low on power.
I had been wishing for a decent gasser to be available but then the E-power came on and that was that.
