Saito FA 170 R3 diff glow plugs test run

Hello, my dear viewers and subscribers ! This along waited video really prepares a lot of sudden and unique adventures during movie making and editing process. I must say, that once again I confirmed for myself, that Saito FA 170 R3 engine is one of the best RC 4 stroke radial engines ever made. During two years I make a lot of testing with this engine, finding shortest possible way to understand it's behavior and clarifying performance details. Exactly after a dozens of hours spent of a bench with Saito FA 170 R3, I understand, that this engine is simply the best for me. I like it by any meanings, from the point of reliability, flexibility, simplicity, greatest build quality and very flexible and tolerant behavior. After testing few glow plugs, was decide to keep genuine Saito SS1 glow plugs, because performance was simply flawless. I also found something interesting in engine behavior with O.S. G5 glow plugs - this unique behavior of the engine was recorded on camera - the engine, having dropped speed, began to rotate in the opposite direction, I was added this capture in video, so you have a unique chance to view by your own eyes. Also, a slow replay of the reverse moment was added into this video.
I hope, that you will enjoy this video, I was worked a lot and hoping that the result will be adequate to the time and labor invested.
Thank you very much for watching !
Have a nice day !
