Been running this thing for a couple of hours now with no ill effects. Also using muffler pressure on the ST 51 and it has about 30 hours on it now. Each has to do what his (or her) conscience dictates but I don't personally see a problem.

You've kinda got me wondering what you think might happen with the muffler pressurizing the tank.



Pe, the only reason I was thinking about reducing the oil was Saito recommends 20-30:1 on the Saito G36 Gasser. 20:1 to break it in and later, if desired, you can drop to 30:1. If I do that, then I can run the same fuel in both the Saito and my Zenoah G26. I may continue using the same mix I use in the ST 51 however because it's not really that much more oil. The Saito spits almost no oil out of the exhaust. There were maybe 10 specks on the wing after about 30 minutes of flying and you almost had to have a magnifier to see them they were so tiny. The case vent is another story as it puts out almost as much as it did when running on glow. I have it running down the gear to keep it off the plane so it's not really a problem either. I guess the old saying "Better too much than too little" applies here. Have a good one my friend.
