  HELP!!!  I'm new, but a highly experienced heli guy.Just finished a large, (840mm) custom hexa. It worked perfect. Then I downloaded an update and now my aileron stick thinks it's an elevator. Not good. Do I need to do a reset and load in an older version? Even my code writing hacker genius buddy couldn't figure it out.

  Advice would be appreciated. Thanks in advance.

  I found a post in one of the forums with a similar problem.  According to that kind gentlemen, DIYDrones shipped two different types of plain yellow ESCs, one of which is not programmable (despite what the instructions say).  That would certainly explain my frustration...

  Happy to skype with anyone who want to inspect my setup.  This is ridiculous since I can't get the basic 3dr kit to work...

  I've been trying to do this with the ESC directly connected to channel 3 (Throttle) on the receiver.  the APM2 isn't in the loop at all.

  I'm doing this indoors.  Probably 70 degrees F, 21C

  certainly didn't intentionally set to NiMh.  No matter what I do, I seem to only be able to get the musical "123" tone (self test) and a long beep when it arms (with throttle low).  I don't get three beeps or two beeps or the musical programming sequence, so I can't get into programming mode.  I've confirmed my transmitter throttle is 0%/100% with no sub-trim.

  Agree with Ramesh that it's unlikely that all 4 are bad.  I'm clearly missing something.

  Dan, I had nightmare calibrating/using 3DRobotics ESCs in low temperatures. However, they worked fine indoors. Also given it is spring here, it works outdoors as well. Are you working on low temperatures?

  Ramesh -

  Thanks for your willingness to help.  I'm using the plain yellow ESCs that come with the 3DR arducopter kits.  https://store.diydrones.com/ArduCopter_ESC_20_Amp_p/ac-0004-08.htm

  Datasheet is at http://stuff.storediydrones.com/ESC%20Manual.pdf

  More ESC trouble. I rechecked everything, and I'm still having trouble getting the ESCs to calibrate.  When I connect the ESC directly to the receiver, I get the "123" tone indicating the self test process, but I don't get 3 beeps indicating it recognizes I have a 3s lipo.  If I drop the throttle all the way down I get a long beep (armed) and I can throttle up the motor. Starting with throttle up, I'm unable to put it into programming mode or to calibrate (only get the "123" tone with nothing afterwards).  Any insights most welcome.  BTW, the ESC key on my laptop also does nothing.

  @Bradley,

       You asked:

  >>Can I use Channel 6 to adjust NAV_WP_IMAX when the conditions are windy?

   

       I'm afraid not.  We don't support the adjustment of IMAX values using CH6..it's not difficult to add but normally the IMAX figure is not all that critical.

  Props were correct.  I think the ESC calibration may not have been working because my LiPo was seriously low.  Recharging now to see if that makes any difference
