Does anyone in this form have the install and user guide for the precise flight vacuum speedbreaks? I have them installed in my aircraft which I believe may have been the first ever plane that precise flight installed them on as they were installed pre STC. The paper work I have with them does not correspond with what is in the aircraft. I'm not sure what activates yours but mine are simply activated by turning the throttle 1/4 of a turn counter clockwise, no activate button, no on/off button just a simple 1/4 to the left. Lets just say this isn't ideal on final for a newer pilot like myself. Any information anyone has would be appreciated.
