Ok guys here is the deal, im not too happy the way my st g51 is running in midrange even when it was warm, its annoying. i run omega 5% med hot os plug and its tuned to as good as it will get trust me. its on an avistar. so a couple of things here, it wouldnt run worth crap in the 30 degree weather. ive heard of people running them in the cold.

does anyone have problems running nitros in the cold? mine just dies constantly and is hard to start.

also pleas give me a couple of engines that AREPROVENto have NO midrange or any tuning problems, i really need an engine that has a nice proven carb unlike the st g51. i know some will tell me that its a fine carb, well its not for me. are magnums ok? i dont know i want to fly in the winter time
