  ok Dan, as i suspected, the calibrations is standard like almost all esc.

  now, u have to confirm one thing, after u have put ur tx on, and moved th to full, and powered up esc, it will some beeps, then after 2 sec supposed to give 2 beeps. Now move th to bottom, if u wait after these 2 beeps for another 5 sec, and it gives a beep 56712 then u have gone into programming mode. so hope u not going into programming mode. Beyond this there is nothing u can do specially if all 4 esc r doing it. Oh, and hope when u doing manual calib, u doing one esc at a time. Should work. Also, just a hunch, hope ur end points for throttle ch in Tx are at 100% and Limit points are also at 100%.  Sub trim to zero.

  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

  Dan, hope u r not keeping throttle tooo long at full initially for calibration, cause then it will go into programming mode, normally, one is supposed to bring throttle to idle within a certain number of beeps. So let me see what esc u have.

  Dan,

  send me the link on ur ESCs, let me go through the data sheet and the procedures, normally ESCs are not complicated devices like women.

  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.

  Dan,

  at times what happens is the in trying to manually calibrate ESCs they may have gone into programming mode, So best thing to do is look at data sheet of esc, and set it back to factory settings, and then calibrate. I had a  similar problem, so i set the escs  back to factory settings, then calibrated and eveything became ok.

  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

  Prop rotation was correct using the HobbyKing ESCs (it flew, but was never anything near stable).  The numbering is also correct.  Mistakes on those would explain the initial instability, but wouldn't explain why I can't calibrate the ESCs or get the props to spin at all now...

  Dan.

  also check ur props r on correctly, Clock and counter clock are places correctly.
