Sal,


EVO engines are re-badged MVVS engines, manufactured by MVVS in Czech republic, by the same machines and engineers, that make MVVS engines.
Some of the models are down-graded (to reduce cost?).
...And the name they are sold under has something to do with contracts and marketing issues... You don't want to know.

You will get the warranty, or service needed (if you ever require service... MVVS engines are very reliable and don't need spares very often), from the MVVS dealer who sells the engine to you, be it Pe, Jan, Morris, Dave Moen, or myself.

Or you can get any part that you need from your local dealer.

For EVO, Horizon Hobby, or any MVVS dealer should be able to supply your parts. They will work even if they have an MVVS badge...
