I'm not giving up on it yet. My first MDS 48 was purchased 3 yrs
ago, and flew like a rocket until the connecting rod decided to exit the crankcase. Horizon replaced it without question. The replacement never had the horsepower like the original, and began overheating, no matter how rich I adjusted the needle.
I returned it after two seasons of frustrations, and they replaced the carb with a new version thats not available yet thru parts.
Seems to be ok now. But as far as longevity??? I'll wait and see.
Probably won't buy another unless I get 3-4 years out of this one.
(without further trouble) Bye!
