Saito FG 21 hand start
Ойын-сауық
Brand new Saito FG 21, first tank (4oz.) first run (not on video) was for 15 min of 3-4 thousand rpm with needle valve at 3 turns open with a MA 15/6 prop.
Let her cool overnite, then today...
This was the second tank with gas mixed 20 - 1 with Stihl's hp ultra 2 cycle synthetic oil. Hand starts nice after 2 chokes, even cold! Still at 3 turns main needle, then closing to 2.5 turns at mid point. Very rich, lots of burbling, but nice idle and transision!

I really like the sound of a four-stroke.
Sorry to all who ask questions four years ago, I missed it. Saito's have been the most reliable engines that I've run, with os engines running a close second. But I did switch back 2 nitro. The engine ran great, I Just didn't need the extra 4 oz of ignition stuff. Also didn't like the smell of gas much
The FG-21 is only the power equivalent of about a 15cc 2-cycle gas engine, or about a .60 nitro 2-cycle. It was probably way too small for your ~1.08 nitro airframe.

Oudeis Eimi Yes, it was the equivalent of the original OS 120, which is what we had in our 1988 Stampe kzread.info/dash/bejne/faOlwcSIaNOflbw.html and I'm now building another Stampe and wanted an engine that would swing a scale prop (18") at a low rpm. Build thread in RCG giant aircraft forum.
Has engine been reliable? Do you recommend it? Thanks

Sorry, I'm the wrong one to ask, we decided to go back to glow 4 strokes, as the gassers add 4-8 oz in extra components. (missed the nitro smell too) So we sold it and got the ASP 180. No problem with the 21 but we wanted a bit more power.
