Chris,  somewhere back in history when I was growing up, it would be said that you have cast iron fortitude, hang in there, flight is eminent.  JohnD

Subject: [FlyRotary] Knock sensor and indicator

Since I have had an issue with detonation, I am contemplating adding a knock sensor.  What do y'all know about this addition.  I do not believe Tracy's EM has a provision for a reading, so, what might be a good route to take.  The brief research I have done shows different frequencies, types etc.   What would be correct for a rotary, both as to a sensor and something to notify me in the cabin?  Thanks.  I am about to replace ALL my apex seals and soft parts and hopefully finally lick this issue....hopefully....did I mention hopefully...determinably...persistent? (heck, I wasn't planning anything else this weekend <g>)
