Is there a secret to getting the .06 engine to develop enough power to get off the ground. I am getting tired of sliding around the ground. I have a LMH and have only made several little hops for 5 to 10 seconds and then the engine seems to lose power and die. I know its not running lean because there is fuel running out the carb. I also notice that there seems to be fuel seeping between the heat sink and glow plug. How do you stop that, I've tightened the heat sink as tight as I can.
