Aleksey Zaitsevsky commented on Thomas J Coyle III's blog post Force Servo camera stabilization
"Hi,
Here is another demo:
https://vimeo.com/82082914
The accuracy of the controlled position for the new servo is not discrete and depends only on the accuracy of mechanical parts. "

Aleksey Zaitsevsky replied to Aleksey Zaitsevsky's discussion Drift of the control signal.
"Got another receiver, no more control freezings. V2.038 is installed. Same problem exist: In simple mode it it very dangerous to try to compensate wind by transmitter, you slowly must push stick more and more until limit is reached and model can not…"

Aleksey Zaitsevsky replied to Olivier ADLER's discussion PPM encoder. Cause of channel freezing found.
"Very strange situation.
Today I got Turnigy TGY-9 2.4 GHz. Every thing is working, no freezings. Space betveen PPM pulses is 2...3 mkSec (0.000002). PPM sequence by channels is 1-3-2-4-5-6-7-8. I tryed to make usual sequence 1-2-3-4-5-6-7-8 - still…"

"I'm trying to understand, is there link between freezings and another problem in my copter:

"Here are the results for the FrSky receiver :

Space between PWM pulses is is about 3...5 mkSec (0.000004)."

"May be this problem is linked with another problem in my configuration - control signal freezing. discussion thread http://diydrones.com/forum/topics/ppm-encoder-cause-of-channel ?"

Aleksey Zaitsevsky replied to Aleksey Zaitsevsky's discussion Drift of the control signal.
"one more moment: when drift of the control signal exist, camera stabilizator is working normally (camera is in horizontal position always)."

Aleksey Zaitsevsky posted a discussion
Situation:V2.033 simple mode, small wind from left side. I'm holding stick a little bit left to compensate wind. but hexacopter again is slowly drifting right. after some time I'm pushing stick to left limit, but aircraft can't fly left. So I must…

"Same problem with FrSky V8FR (2.4GHz)"

Aleksey Zaitsevsky replied to Niklas Goddemeier's discussion Compass off by 45° in X frame setup, Input_voltage setting in CLI
"I have hexa-plus frame, firmware 2.033. Problem still exist. True north pole must be 45 deg CCW. (maybe I must try to test it in another place?)"

Aleksey Zaitsevsky replied to Niklas Goddemeier's discussion Compass off by 45° in X frame setup, Input_voltage setting in CLI
"Same problem (45 deg error) in Hexa_plus configuration. Version 2.029."

Aleksey Zaitsevsky replied to Jakub Sýkora's discussion Reverse both camera servos in Arducopter 2.0.25 etc.
"here it is:
 
g.rc_camera_pitch.set_pwm(APM_RC.InputCh(CH_6)); // I'm using CH 6 input here.// allow control mixing g.rc_camera_pitch.servo_out = g.rc_camera_pitch.control_mix(dcm.pitch_sensor);// dont allow control mixing…"

Aleksey Zaitsevsky replied to Olivier ADLER's discussion PPM encoder problem, loosing CH3 again with new APM board
"I have same problem. Can't read channel 4 and 6. Receiver FrSky V8Fr. I solved my problem by changing channels 4>8 and 6>7"
