OS FS 62 V comparison test run

Hello, my dear viewers and subscribers ! This engine, OS FS 62 V is next in line for the grand comparison cycle of the test runs for 50/60 class of 4 stroke single cylinder RC engines. It was in N.I.B. condition, so it takes time for brake it in, before providing comparison test. I've got two surprises during this test run, one was nice engines behavior and great performance. For the second surprise I would recommend you to watch this video carefully, because all tachometer readings are going consequentially, data by data, so you can easily compare performance in details and you can interpret this data and judge for yourself. Thank you for watching CrazyEngines channel and have a nice day !
