Hi, and thank you for your nice comment ! I’m not selling this engines, I’m just love. this engines and trying to explore it’s behavior to my visitors and subscribers. If you really want to purchase such an engine, please, search on eBay or in Japanese RC shops,. b.t.w., here you can check its availability: www.singahobby.com/index.php/os-fr5-300-sirius-engine.html Thanks a lot for your comment, and have a nice day !

Thank you for your comment ! Absolutely agree with you, FT 160 is the best. B.t.w., OS is currently working on the next engines generation, for UAV;s, and they almost developed twin opposite gas engine with EFI, ECU and with starter-alternator on board, 40 x 2 cm3 volume, very cool features. I can only imagine, how high it is priced. www.os-engines.co.jp/OS_professional/news/191016_e.html . Fantastic appearance. Having great basic engine, like FT160, I think, OS is capable to modify / adopt it to the gas fuel accordingly, with EFI, and other contemporary features. It could be a dream engine. Thank you !

Hi, that's great ! Definitely, it's one of the best and quite universal glow plug harness. It could be even connected to the thick central electrode of the Enya #3 hot glow plug, or to the Enya 4C glow plug, as well. No any connectors works so reliable, as this one from Saito, even small alligators clips doesn't works so well. Thank you and have a nice day !

Yes, of course. I would recommend you to use standard OS type F glow plug, it's very universal. So, also, any of these will work more, than satisfactory: Saito SS type, Saito P2 type, Hangar 9, Yamada YS #4. Few Enya's glow plugs will be also nice, like Enya #3 and Enya 4C type glow plugs. Better to be sure, that it's working, so before installing the glow plug, try to ignite it with NiCd B-size removable igniter, to check, will it light. Please, keep your fingers away from the glow plug tip, it becomes very hot after 3-4 seconds. Hope, this could help.

@@crazyengines88 Thank you!

@@stevebarr9604 You're welcome !

Hi, thank you for your comment / question. I'm not an absolute expert, especially in remote access with the patient (OS FS 40), but from my P.O.W., knocking sounds usually is qualified, as detonation. One of the reasons could be a heavy prop, or too lean fuel mix, or some fuel flow resistance inside the fuel supply pipes. Also, it could be a kind of polymerized castor oil residue somewhere in carburetor. Are you sure also in fuel mix quality ? Did you ever run an engine with this fuel mix ? Here is a few things I would recommend - pls., dismantle the carb assy, totally clean its internals, to remove any old fuel residue. Assemble it back, reset it to the factory settings and start its tuning from the beginning. Hope, it would help. Apologizing for too late reply. Good luck !
