So I've been building a hexacopter.  Today, after 4 semi-successful flights (only small crashes) my APM2.5 suddenly can't connect to the software anymore.  I've done all the normal troubleshooting…Continue

Long story short, I'm in the field trying to gather imagery with my hexacopter and I broke one of my motors.  I can't ship a new motor out before the field season ends, do you think the hexacopter…Continue

"Well... I'm glad you solved your problem, but my problem still exists.  I certainly uploaded the Firmware, and I've connected the APM before this.  I even loaded waypoints on to the APM. Is there some way to wipe the APM or…"

"No. A hex will not fly well with one motor missing.  You end up with a horrible pitch-yaw or roll-yaw coupling.  You may be able to do an emergency landing, but it would be very difficult to fly. I have flown my Octo with 1, and even 2…"

"There are many stories about beeing able to land a hexa when a motor or prop was busted while flying. I tried once myself, having a prop break off and flying with half a prop. I was able to set it down in a field without much damage. But fly it like…"

Richard Boyhan replied to Wolfgang Alders's discussion help me with flying?
"Landing is somewhat of a skill set. First you need to be able to hover. Once you can hover, you then can land. From hover point, you need to drop the throttle just a hair till you start to loose altitude. Watch your rate of descent, if its to fast…"

David Posea replied to Wolfgang Alders's discussion help me with flying?
"The first problem indicates that the copter is not correctly leveled. That said, I also need some info on flying "gently". What parameter(s) will soften the controls? Mine is way too twitchy in stock form.    "

help me with flying?

Hey all,I've finally got my hexacopter up and running, and I'm having trouble flying it straight up and down.  When I give the copter a little throttle, it lists in one direction without me touching any of the other controls.  Any suggestions?Also, how in gods name are you supposed to gently land one of these things.  I try to lower the throttle as slowly as possible, but it still seems to crash land almost every time.See More

Wolfgang Alders replied to Papa Squat's discussion APM2.5 NO GREEN BARS from RC input
"No, it's not.  I have a Spektrum transmitter/receiver and the exact same thing is happening to me.  The receiver is properly hooked up to the APM 2.5, but during the radio calibration step, the bars flash green for a second and then…"

Wolfgang Alders replied to Steve Cremer's discussion Problems configuring spektrum dx8
"Any idea why this worked?  What is the satellite receiver, exactly?  I've tried to bind the main receiver and the other receivers that came with my Spektrum and so far I get no green bars in the radio calibration stage."

Bill Bonney replied to Wolfgang Alders's discussion How do I power the APM board from my battery?
"You don't need all the ESCs to provide power, so snip the red lead on the servo cable to the PDB and it should be ok, as long as it still works as an ESC. The five other ESCs can power the board. You say no continuity between the between the…"
