I have an RDF 900 and have been powering the front side of the of my APM 2.5 from a dedicated battery. I have decided to use this weight to increase flight time by adding a power module and for the board and a second battery. From what I can tell the power module is not suitable to the telemetry radio. How you are folks powering the telemetry?
Thanks for your help

It draw 800ma at full power. The PM provides a max of 2.5A not sure what the APM, GPS, and RC receiver draw. Seems like with 1/3 taken up by the RDF you could be pushing the limits. If the PM overloads, you loose the APM, RC receiver, and Telemetry... sounds like a fly away problem with no way to find the aircraft. The PM says it can work with the 3DR telemetry system that only draws 100ma.
Has anyone used the PM with RDF900 telemetry and had or not had problems?
