anyone ever cut the black plastic knob off the manual elevator trim?

I'm toying with the idea of making a aluminum knob to replace it, but noticed it appears to be pressed on.

Now thats a wild idea. Though whatever you do will need to be able freely and easily rotate 360 degrees.

Sawed off the old black plastic and whipped up a new one today. Here it is with the aileron trim handle

I'll probably eliminate the black "hold/release" piece also.

those look really nice and professionaly made...watch out or you'll be in buisiness.

i dont know much about that system except the elevator trim on an rv 6 i flew in was very touchy. are you somehow gonna make a knob for the piece you mentioned removing?? (the friction ring)

also are you gonna annodize those parts?

yes, I'll be replacing the "hold/release" knob with an AL piece. The friction it supplies is neccesary to keep things where they belong, I also think they help with the twitchiness.

may anodize them, depends on what I do for covering near them. With the right background, I might just give them a high polish....We'll see.

That looks great. I have manual elevator trim on my RV-6A and I am wondering how to mark it to show when you have the trim in take off position. Since I have not flown my airplane yet, I have some questions that may be answered after I have flown my RV-6A. I have a friend who has electric trim for his elevator on his 6A and he is looking at a new option to slow down the response of his electric trim. I think manual trim solves the whole problem but I don't know a good way to mark when the the trim is in the take off position! :bang:
