But again, I have seen guys building up stuff with all sort of things.
Anyways, that look like Rusty's MQ-1 frame.

Randy Ram replied to Andreas M. Antonopoulos's discussion ArduCopter 2.7.1 Released"Spent some time trying to setup my clone F450 with the APM2.It hovers now. But seems to have this funny wobble issue. I have been dropping the Rate P down to lower the effects of this. Currently at 0.09.
The wobble seems to cycle every one second.…"
Randy Ram commented on Darren Stan Oakley's blog post First proper APM2 waypoint test success"Was that a F450 frame? I am building one with a F450 frame. Wondering if you might share the setting you might have for it? I know it might be very well be different depending on the esc and motors I use. But might be a good start.
Thanks"
Randy Ram replied to Randy Ram's discussion XBee Pro 900 XSC Wire with APM2"I'll try again.

Randy Ram replied to Ian forbes's discussion X 8 coax multi Firmware question.. Bird is built but I can't fly!"I got it loaded a few weeks back. Had a few hovers on it so far with the new firmware. I feel like its a little sensitive on my stick. Tried adding some expo, still feels a little sensitive. Think its because of having all the thrust on the quad.…"

Randy Ram replied to Ian forbes's discussion X 8 coax multi Firmware question.. Bird is built but I can't fly!"Well, I tried to change the APM Config file to Octo Quad like the examples posted. But when I compile, it gives bunch of errors. I know I selecting the right board too. Is there anything else I am missing?

Randy Ram replied to Ian forbes's discussion X 8 coax multi Firmware question.. Bird is built but I can't fly!"Hi there Ian.
I am pretty much in your shoe right now. Built up an X8 then figured out there is not easy way to set it up.
Now, I am readying this thread to figure out how to set it up . How is it flying?
Any chance you can type up a little pointers…"
Randy Ram replied to Randy Ram's discussion APM2 PID tuning help"I never did calibrate the mag. Didn't think it needed it, or at least was not in the guidelines I followed from the wiki. Maybe I missed it.

"It's could be the magnetometer calibration. You can start from scratch and recalibrate it. Be sure to keep high current DC wires to the ESCs away from the APM and Magnetometer.
