"Fixed mine by re-calibrating the radio, to include the ch-6 knob."

"any luck? I'm trying the same thing"

"Smoked the flycolor esc after loading blheli on it. So i'm moving to hobbywing.  Also FYI that the Lumenier 45A HV esc is identical to the Flycolor 45A HV ESC"

"3P will be over drawn, its probably around 30C. You need 4S10P to be around 2C OVERALL with those cells. The more parallel packs you add, you reduce the current drawn across the other packs. Play around with it in ecalc.ch paid version has those…"

"I have the same ESC's and Motors and Hobbyking Pixhawk, but with 20" props. I plan on using 4S and 8S. I maiden'ed today with 4S and flew to 5' for 30 seconds and then it looked like one motor just stopped and flipped over, I suspect it lost sync. I…"

"I've been messing with my new M8N for a few days now, seriously driving me nuts! I hate this GPS so far!  Anyway, I have found that it does not like 200ms 5Hz. At that setting it drifts 100m, when I adjust it to 1000ms 1Hz its only drifting about…"

"set the 9XR for 8ch PPM.  I don't think Dragonlink can do 12ch.

make sure you have a jumper on the apm input across ch2 and ch3, and the ppm input is on ch1."

"I fixed mine by soldering directly to the resistors. Used this method: http://www.rcgroups.com/forums/showthread.php?t=2112759&page=17..."

"ha! that looks very familiar, mine did the same. detonated.

Do you happen to still have the PID's? I know it was from 5 years ago. :/"

"just attempted a maiden flight....was a disaster. http://youtu.be/YF12SQE-WZ8"

"Got it going. CH8 switch was too low at 948 when my collective stick low was 1000. I had to change the weight of the CH8 in the 9XR transmitter from 100% to 95% so that CH8 low is now 1000. Then recalibrated the radio in APM."

"did you ever find out the cause? Mine is not arming. Driving me nuts."

"same thing here, thought it was just me"
