Hi i don't know if this is the right forum to ask in but, i have a SIG "Cloud Ranger" and it says that i can use between a .049-.061 glow engine and i was wondering about the diesel engines and how they compare to the glow engines. I've heard good and bad about them: You don't need to replace glow plugs, they can spin a bigger prop, but they don't run good in cold temperatures. I live in Utah so it gets pretty cold sometimes and the elevation makes it so i need more power to fly. So would a glow engine work better for me or should i try to find a Diesel? Also who makes good diesel or glow engines? Im kinda new to glow powered park flyers so i can use all the info that i can get. Thanks
