Hello, my dear viewers and subscribers ! This engine has its very special own story. After the very first run it was sited in it's box, waiting for its internals inspection. Was passed few months, at least. Engine was dismantled, cleaned thoroughly, but I found, that one of the piston pins (from the Cyl #3) was lost somewhere in my workshop. So, if there is no piston pin = there is no engine, so I was ordered this piston pin at RC Japan store ( and thanks a lot, it was delivered in one month). Should say, that I was very surprised with the information, that Saito practically, don't have a lot of spare parts at their warehouse, and if there is a request for some parts are coming, they are manufacturing this parts. The same story was with my piston pin for Saito FA 120R3.
So, piston pin was arrived few day's ago, I start to continue assembling the engine, it was mounted on the bench and now you can watch the results of its first trial run. During engine's runs, I also make a few video thermograms, to understand engines working temperatures, this thermograms were added to the full video version.
Thank you for watching @crazyengines88 channel and have a nice day !
