Ok, so just started using my RM4 on wide open dual airholes this evening.... and WOW does it whistle! Anyone know a quick fix for it, before I get beaten over the head by my DW?
RM4 whistling while wide open?

I don't know about the rm4, however, I have an authentic tugboat rda and it whistled like a tiny tugboat until I realized there were small metal shavings left just inside the airholes from the manufacturer. I cleared them out and fixed. Now I wish it still whistled lol, kinda fun.
I had this happen to me the other day... like a emergency whistle...anyway, I just took off the top cap and repositioned it a lil bit and it seemed to fix it...Do you have slanted coils in it? Thats when I noticed it started...
Nope, no slanted coils. You just reposition the AFC a tiny bit? Mine's dead center on the air hole right now. Wasn't sure if it was needing a rounding of the edges or something. if moving the AFC works well, then I'll just do that.
On a RM2 that whistled, slightly beveling the outside of the hole stopped it for me. Now I bevel all my atty holes with a 1/4" bit by hand just spinning the bit.
Beveled as well. I think it helps with noise as well as airflow, I could be wrong tho.
I might try that with a drill bit tomorrow, on the AFC and the base portion of the cap body. The slight offset of the AFC and the airholes did help for now though. Thanks folks!
