I believe the Cimmaster uses the same hall sensor as RC Exl and CH. The timing is the same.

You're right, I wouldn't give away any of my CH units. I know how good they are and how long they will last in the most extreme conditions. I was there during the testing and field use. They are the only ones that will. So no, I will not give away gold when a lesser material would do. I have no regrets for not doing so.
