Still reading the details, looks like they fixed all my gripes, 4 bolt head, extra main bearing, and a metal block for the carb. About time, and good work Zenoah.
I have one on the way for my Acrobatic...thanks Joe Howard!

the 1/5 car guys seem to think the new motors are the current heli head (with its current porting) bolted to a car crankcase. If this is the case then its only a catchup for the car guys to what the heli motor already has.
It is interesting that they rate the RC engine to have more output for a given RPM while it is using the same displacement. And the PUM version is even more. That says to me that the difference must be in the cooling.
, not heli, But your right about improvements... I hope they do the same for the heli engine,,,
