"No Love Community??
Atleast some of you might have tried to use it? I have been playing with the PID values, but looks like its not doing anything"

"I forgot to mention, I have a sonar sensor onboard as well. I believe those two should suffice.. Please optical flow people, any help?"

Hello Arducopter team,I recently tried out the OF_LOITER mode on my 3DR quadrotor frame. However I did not observe any position hold in it. I browsed through the code and it seems to implement a position PID which seems to be the right idea. Could…

George Khobra commented on Randy's blog post ADNS3080 Optical flow sensor now available in the DIYDrones store!
"Hi Randy, could you tell me what I need to tune and how, in order to achieve the level of performance you showed in the video? It looks really cool.
I have the optical flow and sonar mounted and flying with v2.3/v2.4 at the moment on the standard…"

George Khobra commented on Jean-Louis Naudin's blog post ArduCopter in action: Testing the QuadCopter (HIL mode) on X-Plane v9
"Hello Jean, This is some great work simulating arducopter flight behavior.
Do you know what sensing data can the simulator reproduce? I am modifying the firmware for odometry based navigation in addition to using the GPS at low altitudes. As of now…"

George Khobra replied to George Khobra's discussion Arducopter crash in loiter mode
"One other problem I realized that could affect it is the radio. I am using a cheap FlySky (32 bucks one). So even when I calibrate it nicely and many times, in the setup menu of CLI, I still get the error that 'your radio is not calibrated'. However…"

Hi DIY community,Flying this arducopter is turning out to be the biggest nightmare of my life. I have been using a jDrones frame with the standard 850kV motors and 20 amp ESCs. I assembled the frame fairly easily, configured everything and started…

George Khobra replied to George Khobra's discussion Arducopter drifting on axis between motor 4 and 1
"Hello,
I tried everything that you ll mentioned but it doesnt seem to be a level, vibration or trim issue. I do a hand test and it seems fine. Though I cannot judge too well, other than the fact that overall the quadrotor is trying to level. I…"

George Khobra replied to George Khobra's discussion Arducopter drifting on axis between motor 4 and 1
"Also, does anyone have an idea on why the motors 3 and 4 are switched in the motors test?
I have checked the wiring multiple times and the motor 3 ESC is connected to the right of the red spot on the Power Board"

George Khobra replied to George Khobra's discussion Arducopter drifting on axis between motor 4 and 1
"Well I levelled it a couple of times.. My trim could be an issue since I have to keep adjusting my rudder trim to get my motors to arm (this is after calibrating the radio). I guess because I have a crappy radio set. But when I do a radio test in…"

Hello DIY community,I am a noob to ardupilot and quadrotors so please bear with me. I recently got my Arducopter kit, assembled it, got it connected and calibrated very smooth and nicely. I then performed a hand test and it worked nicely.Then it was…
