If I was to unscrew the radio to take off the throttle click, is there any chance i could mess something up by something moveing inside, or is it safe as long as i dont touch anything.

Not if you are careful. There are probably wires attached to both parts, so don't take it apart two hard. I did this to my BCX transmitter and the throttle is nice and smooth now.

I took it off. I uscrewed the ratchet part. Then I moved the thorttle and it seemed too loose. Like it would move without anyone touching it. So I put some fuel line over the ratchet. Now its smooth, but alittle tight. It will lossen up as the fuel line wears down. I like it!

i like it too. but i do notice i seem to raise and lower the throttle a little when adjusting tail. i do it with out noticing since i dont feel the ratchet. it takes some getting use too.

heres a tip, take plastic safe lubricant (like white grease) and put it on the plastic ratchet part that rubs against the fuel tube, then you can tighten to your heart's content and it wont bind up and have that ratchty feeling still...and the groves in taht ratchet will hold the grease there forever

Bent springs also work for this.

as does plastic fueline placed over the ratches, or simply sanding them off with a dremel tool.
