I just replaced my old cheap transmitter/receiver with a (less cheap) Turnigy 9X radio. I connected the receiver to my APM2.5 board, and calibrated the radio through Mission Planner. 

After some initial testing it seems like the throttle values are too low. On my old controller the stable hover was about 50%. With the new one it's about 65%. And now when I arm the quadcopter the motors don't spin (they did with the old transmitter/receiver). I increased the motor spin parameter from 70 to 100, and now the motors will spin (barely). So it seems like Turnigy 9X throttle values are offset a little. 

Is there anything I can do in the Arducopter software to better capture the throttle settings from the Turnigy 9X? Or is there something I can change on the Turnigy 9X to increase the throttle output values?

I'm currently using Acro mode on the Turnigy. All other values are default v2 settings.
