Well I think I just go with a OS 25LA-s I have been very happy with the way my Nobler flies with the 46LA-s it just runs so nice. I want to thank everyone who took the time to post some of the most informed information that I have seen on this site in a very long time.
You still should not run Omega/CoolPower without adding oil to it Believe it ... you will have erratic, grouchy engines. If you use the 'Helicopter' fuel, you will have adequate oil content, but I don't believe it's available except as 30% nitro. Some of the guys flying speed limit combat around here use LA .25's and 30% Helicopter fuel - I have much better luck with Magnums. I've had two LA .25's to play with but they were inconsistant. One ran OK, the other was slow and never did get up to the speed limit, no matter what we did to it.
