OS FS 52 Surpass comparison test run

This OS FS 52 Surpass is the 3rd contender in my GRAND comparison cycle of the test run of 50/60's class 4 stroke single cylinder RC engines. Engine was equipped with 13x6 MAS prop. and fueled by standard FAI fuel. During the test there were 5 different glow plugs tested, OS, Yamada, Saito and Enya (2 diff OS were tested). So, engine shows very nice character, after several hours on the bench, it was N.I.B., so additional time was requested to brake it in. There were few interesting discoveries found, in details, so, please, watch the video carefully, most important data are recorded on the screen. I'm awaiting for you comments, questions and, of course, your advices. Several times it's really makes my test runs easier. Thank you for watching and have a nice day !
