G'day

This probably does not help you but it might inform you. I had 5 Thunder Tiger engines. I sold all of them. I have 14 Saitos. I have only ever sold one and I was talked out of it. Does this tell you anything?

I have also had quite a few ASP/Magnum four strokes. I now have only one and I bought it to get the plane it was in. It runs OK but not nearly as well as my other four strokes. (Satio, Laser, Enya and OS). It also has a leaky exhaust valve which has resisted all attempts to get it to seal by lapping.

I have sold quite a few OS engines but usually because they were not needed at the time. They ran OK.
