"Also they wouldnt be on the same axis, causing weird accelerations diff's between the two.. It would just get messy. Its much better to just have a stab loop without an imax that can correct for a down'd motor."

I am in the market for another APM, 1 of 2 it doesent matter as long as its a 2560 and has a compass. PM me if you have something!Thanks!Continue

xbee loop speed?
Started Oct 25, 2011 0 Replies 0 Likes
Im running an xbee telemetry link at 5600 baud, but I recently noticed that when I connect to it, my copter seems to be a little bit less stable. Is this normal? Should I try reducing the baud to fix…Continue

basshead replied to Han S's discussion mix and match ESC's?"Technically speaking the IMU should just compensate for whatever variances in throttle response different ESC's have. You should be fine. "
basshead replied to duane's discussion Forever yawing"Damn, my usb connector just broke off, looks like im done testing for a bit unless I can get a small enough soldering iron to put this thing back on. I really really really want the new APM 2.0's to ship"
basshead replied to duane's discussion Forever yawing"You dont need a mag sensor to fly the arducopter... Its to compensate yaw drift in the long run. Duane's problem is his copter is unfly-able.
Do my a favor duane, in the cli, can you run an IMU test and verify that your yaw gyro is outputting…"
basshead replied to Dave's discussion Full state vector from IMU"I am working on just the z-accel alt-hold piece right now but I haven't written anything but test code for it, still fleshing out my ideas.

basshead replied to duane's discussion Forever yawing"Gyro's drift a bit normally, but not so much that its impossible to fly. In my case, I have the mag disabled and still get the drift in planner and in flight. After testing both the gyro's and mag sensor both work in my case.
duane, try…"
basshead replied to Aurelio R. Ramos's discussion Multi rotors, the altitude yoyo effect, and how to deal with it"I havent even looked into any of the AC2 code we have for it Z dampening, that takes a lot of geometry i've forgotten out of it then. I've just been using the IMU test code. Thanks for the heads up though i'll look into it."
basshead replied to Aurelio R. Ramos's discussion Multi rotors, the altitude yoyo effect, and how to deal with it"It seems the Z accel is fine to measure up/down acceleration if you also assume the attitude of the copter is perfectly horizontal. My IMU is acting weird right now so I forgot wich axis it was, but acceleration in a non-horizontal direction can be…"
basshead replied to duane's discussion Forever yawing"I am having a similar issue, I noticed that if I reload the code, setup the radio and everything without turning the APM off, it works fine, i can even fly. But as soon as I restart the APM the yaw gyro isnt taken into account it seems. The IMU test…"
basshead replied to jasonshort's discussion Arducopter 2.1.1 alpha"On my test hexa that I have been using for a while, YAW is suddenly not working with the new build or any past builds.

basshead replied to Leonardo Guarini's discussion MK Hexa XL unstable"I run a similar setup in Y6 config. I found flying it on 3s was super difficult, try switching to 4s and re-doing the entire assembly regarding the APM.

basshead replied to Aurelio R. Ramos's discussion Multi rotors, the altitude yoyo effect, and how to deal with it"I'm not discounting sonar, its fine but it shouldn't be the main thing used for position hold.

basshead replied to Aurelio R. Ramos's discussion Multi rotors, the altitude yoyo effect, and how to deal with it"That's fine, I agree the sonar is useful for ground following and things like that but it shouldn't be a crutch. Baro and just the z accel should be all that's needed for extremely accurate z altitude hold. Now that I finally got into…"

Y6 Pulso 2820/14's with 13x6 APC electrics
Posted on November 20, 2011 at 10:30am 7 Comments 1 Like
Alright guys, here's the big heavy lift y6 I have been working on for almost 2 months now! I had it flying perfectly until a crash involving some motor troubles but now that is all sorted out now. I have re-routed the wires through the arms, stepping down the gauge significantly to do so. I also added lights, and as of now am powering the entire thing on one 12v filtered variable PSU rail and a 5v BEC for just the radio.
My wireless video TX is coming in next week and I already have…
