I bought this second-hand heli at a time when my IC flying club had lost it's flying field's parking facilities. At the time I was also a member of an electric flying club, so I could fly electric-powered fixed-wing models. But I thought I'd miss IC-flying, so I got the LMH thinking I could fly it in my back garden. Then I joined another flying club and was able to continue flying my IC fixed-wing models, and the LMH got put on the back-burner - for more than two years!
The two-year-delay brings us to 1st September 2003, when I finally got-around to flying my LMH . . . . and in my own back garden as originally planned too:
Initial attempts failed to get the engine running reliably. This turned-out to have been caused by the previous owner having damaged the carb's needle, but the damage was soon fixed with a little careful filing. After this I discovered that the engine was prone to suddenly cutting-out. This turned-out to be due to the cylinder head becoming loose as the engine warmed-up. Blue Loctite cured this problem
The heli needed just a few low "hops," and some tweaking of the "trims," to achieve good stability. It was then so predictable that I was able to assume my more usual (seated) flying position during the third test-flight:
The LMH has turned-out to be a really worthwhile exercise. I like flying it a lot and for a fixed-pitch heli it's amazing what it can be made to do. I've found that it will do stall-turns, loops, rolls and a neat split-S too. Great fun-flier - even crashing it doesn't end-up being traumatic either, as due to its sturdy construction it can normally be straightened-out and flown again straight away
