Doug,
Jim Maher came up with the "Ammeter" IVO prop pitch idea and can give you the answer to that question...............Also John Slade has reported that after the aluminum disks get impregnated with
carbon from the brushes that brush life increases dramatically but I cannot remember the hours that
John reported................

Chris: Are you using an ammeter to set you pitch by chance? If so how much of load is on it at fine vs. coarse pitch settings? Also have you had to change out your brushes yet? I am hearing we should expect to get about 15 hrs. on them before needing to change them out and wondered if your ground testing had validated that number yet...
Thanks for the information.
