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?
