"This is exactly what I an trying to do. Thanks for sharing.
But I would like to add a feature which can decode and encode Mavlink protocol such that signal strength can be shown on GCS(may require a arduino with more flash space). And a TCP transfer…"

"The ugliest face of DJI is not their technical issues, but their attitude to technical issues reported on forum.
DJI is a advertisement sponsorship of one of the biggest RC forum in China. Many DJI users report their issues(Wierd attitude behavior…"

"Thanks for reply, Philip.
I went through the function drift_correction function in class AP_AHRS_DCM. But I could not find any logic in the code that will redirect to other accelerometer based roll-pitch compensation when GPS is not available(yaw…"

"Brillant job. Thanks a lot William.
I went through the code in file AP_AHRS_DCM.cpp, it seems ArduCopter runs only this algorithm on APM2 for gyro drift compensation.
But it relys on GPS and my APM2 flys perfectly indoors (with GPS intalled, having…"

"DJI deserves it. In fact it is very necessary for DJI. But I don't think it fits DJI's flying-away bug."
"Everything here is even MORE unacceptable with DJI, because of its stupid, unreasonable and very dangerous crashes."
"Hi, Randy,
Thanks for the nice technical details. I will surely look into source code of pixhawk in the furture."

"I am not quite sure about my idea, but it seems to be related with extend kalman filter in certain vabration condition. DJI declars that their flight controller use kalman filter, and there are many crash and fly-away cases which are not…"

"Yes, A warning window may be quite helpful. Or keeping everything unsaved before one clicks finish in Wizrds, this is the default Windows program behavior I got used to.

"Hi, Gustav,
Thanks for reply. I did't config in air. I adjusted some paramaters in evening before the crash and wrongly clicked the Wizard then closed it without doing anything. Unfortunately, Wizard changed by frame type to +4 without any…"

Hi,I got a wobbling crash from 1 meter height for my X4 copter yesterday. The uncontrolable wobbling happened 2 seconding after taking off and was caused by an unexpected changing from X4 to +4 in my APM 2.6.The problem turned out to be a Mission…
