I am using the TxPID module for PID tuning.
Initial tuning is difficult because I can't start at 0.002 and move to 0.008.
When I put a min value of 0.002 and a max value of 0.008 for Kp Roll in the TxPID section on bank2.
After arming the quad I can change the P value for Roll in bank 2 using the potentiometer on the transmitter from 0.005 to 0.008.
It seems that the minium value in the bank is always: (min + max)/2???
Any suggestions how to get the real min value in the bank?

Hi.
Have you calibrate the accessory channel linked to TxPID? There are no limitations in min/max values.

Hi,
Thanks for the suggestion, I did check this to be sure. In the input section I used manual calibration to set the minium and maxium values for accessory channel 0 linked to TxPID. The min value is set at 1000 and the max value at 2001, seems to be quite normal.
Any other thoughts?

I never had a Rx that is 1000-2000 µS. But I'm using Spektrum...
What fw are you using?
Have you upgraded from OpenPilot?
Can you attach the uav settings (File > Export UAV Settings...)?
