"Abbas,
I also experienced this problem. I was trying firmware 3.3 after upgrading from an earlier version, on a genuine Pixhawk, some time back. After much searching I found a discussion telling the inquirer to reload the software by first loading a…"

"I put a genuine 3DR APM 2.5.2, that was collecting dust, into my Quanum Nova to replace the factory APM that was in it. (The factory stuff requires custom versions of copter) The Loiter/AltHold pulsating started as soon as I upgraded to 3.2.1. After…"

"I just got one as well. I am surprised by how fast it is. It is also a blast to fly."

"I read a post by Randy saying the PPM Channel Mapping issue would be resolved before 3.3 went final. Does anyone know if that is done?"

"Maybe not everyone would consider it a bug but the problem of ppm channel mapping is still on the table and for some of us that is a real issue when it comes to Pixhawk. I've been playing the APM/Pixhawk game for a couple of years now and my APM 2.5…"

"Does anyone know when the RCMap issue might be fixed? I know Andy said "soon" but was hoping someone might be able to narrow it down a bit."

"Thanks Andy. Much appreciated."

"I just ran into a strange issue on my Pixhawk (Genuine 3DR). It's been months since I last had time to work with it and decided to try out 3.3 as I needed a good challenge. I previously had been running 3.1.5 and everything worked fine. Since I am…"

"One thing I didn't see mentioned is whether you have completed the ESC calibration procedure. Take a look at this page and see if it helps. If not then one of the Grand Masters will have to help. ESC-Motor Calibration

"Normally this is cause by the failsafe position of the receiver. Spektrum/JR receivers set failsafe when the binding process occurs and once the aircraft is fully set up and trimmed, you redo the bind process so the receiver sets the new positions…"

"One small item to add to Gerard's excellent post. The Spektrum receivers set failsafe when the binding process occurs. That's how the AR8000 will see the new endpoint as the failsafe position. If you rebind at any time in the future, you will have…"

"Graham said it and I agree, correctly configured and with enough reserve power on board it will fly thousands of miles to a waypoint and return safely to the launch location if programed to do so. That is, of course, assuming enough reserve power on…"

"Hi Shyam, I have a post in another thread where I make a reference to this exact problem. My particular camera is the one I use for FPV and is a SecurityCamera2000 PZ042 board cam that has been put into a metal case also sold by SecCam2000. The cam…"

"That steel screw attaching the Mag to the GPS is probably the source of the problem. See if you can find a fastener made from nylon, aluminum, titanium etc. Some stainless is non-magnetic but not all stainless is. Any ferrous metals near the…"

"They are great FPV platforms. Be very careful of how fast you fly though, they develop control surface flutter and when the control surface is deflected fully, the corresponding wing tip or the horizontal stab can flex the opposite direction causing…"
