I can tell you over the years, students always role the throttle friction back off, and I always roll it back on because many years ago, flying one of the 1st jobs I had, worked all the time with this instrument mechanic who's known for being sent all over the world to work on instruments by Instrumental Copter Corporation. He's an awesome mechanic and early on, he taught me, he said one day he goes, "Tell your students to quit rolling the stupid throttle friction off." He said, "You have all these guys that keep having all this trouble with RPM and you guys are having all these engine problems. He goes,"The problem is they keep rolling the friction off." Every time he comes down here, that friction is off. He said, "These aircraft are designed to operate with that friction on and I can tell you from experience in the times I've had a student who is having trouble, struggling with RPM, I'll say, "All right, let's check the friction. Is it on? Is it off?" It's always loose. When the frictions off, that throttle can just move around. The RPM can go up and down. When you have that friction on there, it helps you maintain the RPM. Let's just take a look at real ... When you're doing pre-flight, check this thing. This direction is all the way off. Throttle is loosey-goosey, moves all over the place. If you crank it on, you can go all the way, that's too tight. There's all the way. That's probably too tight. From the throttle or the friction off to on, I go generally about 3/4 of the way on. Depending on the aircraft you're flying, it could very a little bit, but in general, out of all of these instruments I've flown over the years, around 3/4 of the friction is about what it takes.
