I purchased one way back in 1985 along with the first shipment of Model Tech Dragon Ladies. The engine is heavy, but ran like a sewing machine. It never let me down. It did require an electric starter, but once it started, it did'nt stop. Very fuel efficeint too just not a powerful engine. Its been along time, but I think I got the whole package from Jim Goad for $200. The Dragon Lady was an awesome flying plane. I'd luv to have that one back.
