I'm a relative newbie--might as well admit it--I have several helis and recentlyI bought a Raptor 90 std with the 0S 90 sz-h ringed engine -very stable and easy to learn on. I'm just doing easy flight and hovers for now. After about two gallons of flying I noticed fuel dripping (about one drop every 3-4 sec) right where the head joins the cylinder--I've checked everything--it's not running down from anywhere (such as the carb) and none from the fuel lines. The head bolts are tight. The glow plug is firmly seated. It's leaking right out of the junction between the head and the cylinder at six o'clock (facing the nose). Theres no smoke coming out of it and it doesn't appear that anything is blowing out where the leak is. I think I have the engine leaned right and it runs great. It's not very hot at the end of flying, does not smoke excessively and doesn't bog at all. Idles smoothly. Seems to me that if there was an actual leak around the head it wouldn't run right (if at all) and I ought to see some signs of something blowing out of that area. Am I missing something obvious due to ignorance or what??
