Our chapter did go ahead and buy the Dyna Vibe which we received a short while ago. So far we have used it on several planes and everybody noticed a definite reduction in vibration levels.In my case I reduced the IPS from .68 to below .05, a big improvement! It did take quite a few attempts to get it to that point ( waaay more than 3 ) but with more experience we should get better at it.
Thanks to all that answered my querry about the Dyna Vibe.It was well worth getting and there are a lot of planes in our chapter that are going to benefit from it. Per KR2
