"Impressive bunch of work!!!  thanks dev team!"

"I built this one: http://www.diydrones.com/profiles/blogs/coptergcs-android-ground http://code.google.com/p/copter-gcs/wiki/MainPage?tm=6 based on Bart's work, maybe you could contact him to update the GCS to the latest version. "

"Motor mixing is just a matter of knowing how much "stregth" must a motor apply on pitch and roll depending on it's position, no need to mess up with angles, only distnaces from center in percentages.... hope you get the idea. Once…"

"Hi Josh, check this out, ardupirates motor mixing. I wrote this when I made the V mixing for the arducopter/ardupirates, hope it helps. Dani"

"Awesome Dave!!  thanks for the work!"

"Hi, you must follow the pictures in the wiki, yes it is correct to have those different direction up and bottom, as the motor mixing is designed to work with those directions. As for the motor heat, it is normal when the motor is designed to urn…"

" Sorry to hear that :-(  that kind of crash is never nice."

"I always use a separate BEC to feed the APM.... just another idea..."

"I removed a lot of interference, by twisting all power lines in the quad, you can always give it a try. Dani"

"Correction, I'm using 11x4.7 on top, not 11x4.5. I just read somewhere (don't recall where)someone stating that, using bigger top props gave good results, and it does for me, it's not based on any scientific study ;-)   It…"

"I use bigger props on top, and it seems to work better. That is 11x.4.5 top and 10x4.5 bottom. Has anyone tried it??"

"Hi Stephen, as stated in the wiki FAQ: "My copter increasingly swings up and down in alt hold. It eventually get's down to the ground: Your THROTTLE_P is too high or low. You don't need a lot of P to do alt hold. Think of how much you…"

"More or less, yes, as long as you fly over flat surfaces. I was just able to do a couple of short flights. Next week I'll do more testing."

"Hi Stephen, I use sonar for the AltHold :-)  Although it doesn't like to fly over grass ... sonar loses accuracy as grass is not a good surface for sound bouncing.  The accuracy I get is at low altitudes 1.5 to 2m, so only the sonar…"

"Hi all, After the holydays come back, I hadn't had the chance to to test 2.7.3 until now. My setup: Y6 Hexa (aka Skybot)Arducopter v.2.7.3Default parametersMotors:BC-2836/7 1120kvProps:Top: 11x4.7, Bottom: 10x4.5Weight:2.1kgr + 5A Batt. Size:…"

"Hi Arthur, some time ago, I wrote this "how to", for motor mixing. You can start here: http://code.google.com/p/ardupirates/wiki/motormixing Dani"
