Saito FA 65 comparison test run

Описание: Hello, my dear viewers and subscribers ! This video continues GRAND cycle of test runs of a single cylinder 4 stroke RC engines from 50/60 displacement class.
This time this is Saito FA 65, well known engine, which was in production over 12 years, and went through at least 2 modifications.
It will be interesting to know, that at last modification, compression ratio was lowered, from 12,7:1 to a more practical 8,6:1, which makes engine running more flexible and fully eliminated kick - back habits during starting, as well, as throwing of props in the air.
During this test run, I was tested 4 different brands glow plugs, all TOP and IDLE speeds were recorded, so, if you need some data \ correlation in between glow plug type / Saito FA 65, you can easily find this numbers in this video. To make test results comparable, I was using 13x6 MAS prop and standard FAI fuel for all engines in this test cycle.
After a couple of test runs provided, I was found, that Saito FA 65 is an excellent engine, very reliable, flexible, with excellent power / weight ratio.
More details and all performance data you can find in this video.
