Thr IN Spikes

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.

Setup:

3DR Quad C frame with standard ESCs and motors.

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.

    I seem to have fixed my problem. I changed the frame rate on my transmitter to 11ms and that seems to have cleaned everything up. I don't know exactly why but I will do some more research and see if I can explain it.

    Further testing and updates tomorrow.
