So, when I added the CRU to my REX7 E2, that is what overloaded the RX outputs of the CB200. Makes sense, because all prior flights didn't have the CRU. Funny that I put a 3rd battery in the plane to power the gear and still ended up overloading it.
If Cortex would have included a wiring diagram in their quick start guide... I guess the new generation relies on Youtube for instructions, I'm old school and like to read manuals and drawings. It is a sign I'm old and being phased out.

I only wanted the CRU to end the pesky buzzing of a gear door servo. The JP controller worked great otherwise, and had another power source.

I just got a response form my Digitech dealer, and they will not help me get it fixed. I tested it yesterday and it works okay, and I wanted a new cover, because in the crash it got scratched and dented.

so it goes.
