ORIGINAL: noobflyer01 thx jcerv for the heads up. now when you say tuning and keeping the engine alive. what kind of things are we talking about here. i'm i gonna be mechicanically adjust this engine constantly? i don't have any experience with engine type birds before. i did have a nitro plane about 20 years ago. even back then i didn't have to do much as far as keeping the engine alive. just filled the tank and flew. didn't have any problems with it as far as i can remember. please fill me in He's talking about setting the needle valve too lean,or to rich. The motor will smoke allot and blubber if too fat (rich),or worse yet,if too lean,it will sag and seize up. Once you get it set right,you shouldn't have to be adjusting on it constantly,UNLESS you go to fly at a higher altitude,or the weather turns cold. I used to fly my pattern planes,I would start out in the spring with the same setting,as it was set in the fall of the previous year. Once it got warmer (read summer,and hot) I would give them (1 click rich) to get them right,and fly all summer. Then as it cooled down in the fall,(right back to the setting it was in at spring time. I see guy's cranking on the needle valves on their motors,at the field. It's a habit![)] they do it so much their motors are constantly running wrong most of the time. Instead of cranking on the needle valve,look for problems else where,like bubbles in the fuel line (you have a air leak) and will run lean,or a clunk weight stuck,(inside pickup line too long, or change the glo plug,some don't last very long (read running too lean). If the detent (little spring arm on the valve) is solid) your settings won't change day to day. Once a glow engine is set up right,they are very user friendly,if your not sure how to set it up,go to a local field,and ask for help from a experenced (guy who know's what he's doing) pilot. You can tell them from the other pilots. They are the one's flying,and their planes/heli's don't miss a beat. While the others are adjusting,motors quitting,motors not idleing,flam outs,ect. Ron
