as a beginner and starting to learn how to tune the engine its a little scary messing with that needle valve when the plane is at full speed. not bad if someone is helping you but i go to my field very early and usally no one is there. so i was looking for cheap and easy ideas for a tail tie down. i thought of a long screwdriver in the dirt and wrapping a rope around the tail and clipping it to the screwdriver. is that good or any better ideas?
