RE: Evolution 58
Greyhound,
This engine is an MVVS 58 cc, produced by MVVS for Horizon Hobbies, to be marketed under the EVO name-plate.
I market MVVS in my country and another dealer does the same for EVO.
I am told the EVO uses the single magnet ignition, where the MVVS uses the newer dual-magnet unit, but I have not yet seen one, so I cannot be sure.
