BTW, i created STABILIZE MODE that use PITCH and ROLL angles to stabilize the cam.
you can adjust the tilt  angle offset using settings/CAM menu;

ACTUATOR_DELAY is only a delay to initialize the motor module not the start motor procedure.
If i remember, the actuator delay only work with MKK, asctec module (i2c modules), so the pwm supervision not use this delay.

Happy New Year folks!

(Liza/M 1.0/Quadcopter/v4.2.0_stable-2-gd155873)

1) A question concerning the standard arming procedure for the motors (throttle min and full yaw). The motors start and shut down after pushing the yaw both to the left or the right with a time lag of 1 sec.
Is it possible to alter the sequence to start the motors only by pushing yaw to the left and shut them down only by pushing the yaw to the right?

2) Additionally, I want to reduce the time lag. Is the 1 sec standard or just a result of my configuration? Can I use the parameter ACCTUATOR_DELAY_TIME within the airframe to reduce the time lag during arming sequence? Which values are appropriate? Any suggestion is appreciated!

3) We are still trying to implement an automatic heading cam even if it takes some C-Code modifications in the end.
The idea is to "tilt" the cam manually (let´s say with up/down buttons from GCS) and later automatically by reading the pitch value from our Quad. So no panning whatsoever.
With the configuration files attached I get the following error while compiling:

firmwares/rotorcraft/main.c: In function 'telemetry_periodic':
firmwares/rotorcraft/main.c:176:1: error: 'booz_cam_pan' undeclared (first use in this function)
firmwares/rotorcraft/main.c:176:1: note: each undeclared identifier is reported only once for each function it appears in

make[1]: Leaving directory `/home/and/papa_42/sw/airborne'
make: *** [ap.compile] Error 2
make: Leaving directory `/home/and/papa_42'


Any ideas?

Cheers!
Andrius
