Hi All,

I have a BVM Smooth stop that I upgraded to the smooth stop II plunger. When all aired up to about 60 psi, I here a little hiss coming from around the plunger and sleeve. Do the sleeves wear for some reason? The Smooth Stop II plunger is brand new, purchased 3 weeks ago.

Thanks for you time and help!

I love everything BVM apart from Smoothstop's. Every single one I have had leaked. Got rid of them all, fitted a non proportional valve and kept the O rings lubed.

Wow!! I just installed a new BVM Smooth stop in a bird I bought used a week ago and it is still holding air. I also have a Hawk that I pick up last fall used with first verson smooth stop valve that I have not flown but it holds air after testing new radio for the past 3 days so for. I have a FEJ f-16 with there brake values and it is junk! I new to the brakes so what do you use for the non-proportional?

I have never had a problem with any of the BVM Smooth stops that i have. If you are hearing a Hiss pull the plunger out and make sure that you did not plug the hole on the end with O-ring lube if you relubed the O-ring before you installed it.

Also you have to make sure that the linkage is running in a straight line with out any binding on the plunger during the movement of the servo and plunger.

Go on the BVM site, there a recall on the smooth stop!
I think all the postage is free!

Have to say I have owned/used multiple smooth stops over the years and everyone one of them leaked at sometime. The fix is just to simply relube them or in some cases replace the o-rings. Personally, I think there are better choices such as jet tronics brake valve or UP6 but each to their own.

If you take advantage of the free upgrade, I will be shocked if it ever leaks again. How's that for confidence! LOL

Now if you pack it full of dirt, well, you can keep it.

Thanks Dustin...I got a message from Harley. I know he will help me out!

Hi,

If you ever do get a chance, give the UP-6 a try. Never looked back when I need proportional...

I have two Smooth stops. One new Ver II and one I converted. Both hold air for a long time. I do coat the o-rings and sleeves two or three times a season with air tool oil. Never use Vasaline on these o-rings. Ever.

BVM had a recent problem with the Smooth stops. They will repair for free. Give them a call. This was posted on their website a few weeks ago.
