My only ENYA 2 stroke is a 1983 vintage 45 CX / ABC motor. It's been a horse. It was flown hard for 2 yrs, , then stored for 14 yrs, now for the past 3 years flown almost continuously on a trainer that sees action almost weekly for goofy fun aerobatics (yes,that's right!).

It's never had any service or maint other than crash repairs, and it's dead-nuts solid and reliable.
