I can't find it anywhere online. What fuel tank sizes should I use for the saito 115 and 125 engines for 10-15 minute run times?

Thanks

I get about 15 mins on 16 oz out of my 125a, im running a 16X6 apc as shes a bit rich about 500 rpm under peak

Have a look at the following page from the "unofficial" siato engines website. They recommend an 18-20oz tank for the 125a. I have a 125 for a 20% extra 300s but can only fit a 14oz tank in the forward compartment. Haven't run the engine yet so can't commet on run time - would have been happier with a 16oz tank though!

I also used a 16oz on my saito 120 for 10 minute flights. Plenty left over.

About one ounce per minute depending on how you are flying. That's just how I figure my tank sizes, I usually can do a lot better then that unless I'm doing a lot of vertical type of stunts. The 1.25 in a big Tiger Moth will fly all day on a 16 ounce tank but in an Extra about 15 minutes most the time.
