I'm experiencing short little bursts of throttle in testing. When I do a radio calibration and if I wait long enough the "max" on various channels will quickly spike to a level I can't even generate by moving the stick to a far position. (This is without ESCs plugged in or motors running.) The problem seems to occur when the ESCs are connected and the motors spinning.

APM2.5 Running V2.8.2
Upgraded LEA6 GPS
3DR 915Mhz radio
Spektrum DX8 Transmitter
Spektrum AR8000 Receiver
Spectrum TM1000 telemetry module
Log attached showing the Thr IN spikes.
I'm going to begin removing components from the system tomorrow for testing but I thought I would post this just to see if anyone had any ideas.
