"Check that the radio and receiver are working correctly by another means. Ignore the FC and connect servos directly to the receiver (if that's possible) and see if they work OK. If not, test the Tx with a different receiver if you have one.
"I'm in Adelaide and bought a Talon plus extensions direct from the maker in China. Turned out to be the cheapest solution at the time too. There's useful information here
I am installing a new Pixhawk in a quad and trying to calibrate the accelerometer. I have attempted this now at least a dozen times but each time it fails. The reason seems to be that the process is being disturbed by the constant stream of error…
"My HK board worked fine using Arducopter. GPS support is just the same as if it was using an APM and works perfectly. The downside is that the port was done once for quads and hex frames and has not been repeated for later versions of Arducopter -…"
"Look here for mag suggestions. Also a link to the Arducopter port. Bear in mind that it by no means a current version of Arducopter and there will be things in the current GCS that won't work or will work wrong. If you intend to persist I recommend…"
"I have 2 Revos. The first I acquired when they came out and, after a frustrating time with Open Pilot eventually installed the Arducopter port on it. I've been using it unchanged in a camera hex since then. Recently I bought another, this time from…"
"As this is your first try you might save yourself a bit of early hassle by using the internal compass, ie don't connect the external compass yet (unless you have to.if there proves to be too much interference with the internal once you've got it all…"
"That's for 'Copter. In 'Plane its when it gets GPS lock. Presumably there is a good reason for the difference but someone else will have to tell you what it is."
"Its worth mentioning that the emergency stop will reingage the motors immediately if the switch is turned off within the disarm time limit. If it's on a momentary switch an accidental knock/switch off would be temporary and probably not have a…"
"The only other FCs I use are with OpenPilot (Revo, CC3D) and Ch 2 is reversed on them. I suppose the expectation is that this will be noticed in the radio calibration process."
"Nothing has changed as far as my testing goes, I have been reversing channel 2 on my radio since ER9X on my 9X radio years ago, later with OpenTX on Taranis."
