"Yes, I do.
It's complete with motors, ESCs, APM flight controller etc, and is ready to fly. If you're interested in buying it, PM me and i'll take some photos on it."

"Joel,

Depending on where you are, I have a 450 size quad with Naza, GPS, OSD, camera and video transmitter for sale cheap over on the UK Drone Junk Yard facebook group, complete with 2x 4S batteries and some spares. Just needs a transmitter binding…"

"Is there foam over the baro sensor inside the pixhawk case?
If it is missing it could cause this.
[No direct experience of pixhawk, but APMs have this]"

"Can you swap that motor to another position, then same for the ESC - should quickly be able to work out which component is faulty."

"My issues...

Lack of redundancy - quads and hexes will generally fall from the sky if any prop / motor / ESC / cable fails. Octos are better.
Battery life issues - many crashes are the result of the low battery warning being too late (or not at…"

"That appears to be a hybrid, as I suggested?"

"Sorry if I sound negative, but I'd say you have little chance to get this to work.
You need two props to spin the opposite way than the others for a start, so those two would need additional gearing.
As multi-rotors are so unstable, they need very…"

"Is there a power monitor fitted to the APM?
Is the APM configured to use it? Does the correct battery voltage show when connected to Mission Planner?"

"I just took a screenshot of the PIDs i'm using for someone else.
Try these and see if it's more stable (see attachment).Quad PIDs.jpg"

"I've tried it, but it doesn't seem to work.
I have it set on flight mode 4. Select it, FPV/minimOSD screen shows loiter, and it behaves like normal loiter.
Hooked up to MP now, if I select the switch combo for that mode it highlights it in green…"

"I appear to have resolved this.
There wasn't much I could do about the balance, as it is a cradle for the GoPro, with no movement. In the pitch axis it was pretty much in balance anyway. In roll it tends to fall to the motor side when powered off.…"

"You can set the range limit either in the DX6i menu, or in the gimbal settings.
Mine is set on the transmitter:
Flaps:
NORM ^12 ELEV 0
LAND ^60 ELEV 0

See if that works for you."

"I couldn't get it to work properly via the APM, the camera would shake constantly, so mine is connected directly to the receiver.
If anyone knows a solution to this, let me know!

Alan."

"Bump... Any suggestions to resolve this?"

"If the log stopped before the flight ended, it may be because of a 'brown out'.
My guess would be that the gimbal is drawing excessive power.
Is it connected to the same BEC as the APM?
Maybe try a flight with the gimbal mounted, but NOT connected,…"
