XAircraft Old User, Old Copter - x650 - Flashing Pilot Light

Yup I'm a noob here, first post is a 'problem' .... sorry for that ...

Despite having 3 or 4 satellites indicated and toggling between -2D and -3D lock the pilot lamp never goes solid, it is correctly connected to output 12 on the flight controller, the copter refuses to play nice and is a pig to keep stable. When lifting off the copter always moves right and you need to apply stick to stop it, adding trim simply results in a drift in the other direction, you can't let go of the sticks at all if you want to stay in the air, the altitude hold is on a gain of 30, tried various settings but you are constantly adjusting the throttle to stay in the air at a 'fixed' height, everything is way too sensitive and I have my stick gains down at 6 for all directions.

I only bought this copter as a 'trainer' for doing some aerial photography / video having moved up from a much smaller 'no name' quad. I'm starting to regret it, there are very few spares available, the support seems non existent from the UK 'supplier'.

I have an FC1212-S running firmware version 1.34-b, AHRS at V1.20, GPS 0.9 - I've no way to get at anything newer - at least not via Google, I'm forced to use Xaircraft config software 1.8.0405 since I can't find a download for the older versions. There are no profiles showing up in the setup so I'm sure that's part of the issue with the drifting - that and the lack of GPS but then it shouldn't drift even without GPS in 'no wind' conditions.

Anyone have a 'good' profile for an FC1212-S so that I have somewhere to start - or any other ideas why the Xaircraft profiles are missing before I create my own ...

Easy? You call that easy?
Hi Ben,

Welcome to the forum. I hope someone can help. :nevreness:

Is Ben Kenobi your real name by the way?

Nah not the real name - comes from a Star Wars heritage ... get called the Jedi master at work ...

Not sure if the AHRS isn't barfed, can stay horizontal but can't hold position or altitude, and the GPS lock is a joke.

XAircraft have removed all links to older config tools and PID setup files so unless somebody has them stashed away I think I'm into messing with the PID settings myself, not sure if I can be doing with the hassle to be honest. Nothing I do to the PID's will matter if the AHRS isn't functioning properly anyhow.

I ran XAircraft Center 1.8.0405 and looked at the diagnostic 'graph' - it was devoid of data - I am not able to access any of the 'menus' described in either documentation nor many web sites.

I've flown a few quad's so I know it's doing things that it shouldn't - just can't find the resources to solve it. As it stands with this one it is 'entertaining' to fly but absolutely no fun and far too much like hard work. It goes up like a rocket or comes down like a brick, won't hold altitude, throttle up a click, down a click, rinse and repeat only the response to the up and down isn't consistent, release the sticks and it has a mind of its own.

Spent the afternoon checking motor centres, spindle angles etc etc but the way the arms are mounted there's no adjustment possible anyhow, I did have to straighten two motor mounts (motor spindles not vertical. Clearly bent because I have a new one here to compare them too, made no damn difference though.

I've wasted a lot of money I think :dejection: ...

When I get home I'll look to see what files I have. I should still have averything you need. I would say at first you need to reflash the AHRS with the latest firmware (again, I think I have it). We can go from there. I still have several of the old 1212 units.

Very much appreciated, tried a few things, including recommendations found on RCForums - re GPS issues on the V1 X650, it seems that this is not an unknown issue and there seems to be no resolution to it - at least that doesn't include a hardware upgrade - disconnected GPS - much improved however not hovering though and still drifting, won't hold a vertical line - tried in a wind free environment, no pitch or roll input and it still drifts.

Have checked some measurements and there is one bent motor mount and the arms weren't in the same plane, have them all on the bench now wondering what the best way to make everything line up is. The bent motor mount I'm fairly sure that I can straighten but how to make sure the arms are in the same horizontal plane when remounted.
