As some of you may know, I installed a hks ,3:47, four blade powerfin, in my Twinstar with the attempt to make a plane that my noise sensitive runway owner would accept. I flew it out of my home strip for the first time last night and got the double thumbs up from the runway owner and closest neighbor!!! It has enough power that next flight I will do a reduced power climb and be even quieter! The people watching my take off said it was quieter than the 85 hp Fleet Canuck that flys regularly out of here (my goal was to be as quit as him)
I anticipated poor performance in either climb or cruise, and although I realize performance is somewhat subjective, I am very happy with both. It climbs at close to 1000 ' per min. and will accelerate in level flight much faster than I care to go (80mph).
Conclusion: I believe the hks is ideally suited for replacing the 503 or 582, and I now feel it would have enough power for a light Mark 3, as my heavy twinstar has abundant power, even with the lower performance of the 4 blade prop.
Rob Cannon ps. if anyone has any questions on the hks/kolb install I would be happy to help.

That looks like a really nice, clean HKS installation ! Your report seems typical for HKS engines, they are expensive but everyone I have ever read about just loves the HKS. They use them in trikes with very good results also.
