RE: Favorite engine?
My two ZDZ 50 NG's both run very well. No dead sticks on either one and I fly very low and slow.
My brand new Brillelli 60 has not been started yet but from what I hear it will be my favorite.
PS: Pat service is an issue. Neither of my ZDZ's needed service until I totally drove one into the dirt doing a double waterfall way too low. I called to get a quote and decided not to fix it ($300 for a new cylinder head and carburator and only assuming 1 hour of labor, fagetaboutit !!!!).
