@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. 

Front right CC

rear right C

real left CC

front left C

Dan,

just do a second check on the following. 

1. Open throttle slowly, and see if prop rotation dir is correct.

2. r u sure u have the numbering correct for plugging in ESCs. front right is 1, rear left is 2, front right is 3 and rear right is 4. I am asuming that u are using X configuration

Desperately need ESC help.  I've been trying to get my quad flying for two weeks with no success, and I'm fairly certain the problem is an inability to calibrate the ESCs.  I've followed all instructions to the letter, tried both automatic and manual modes.  Initially I was using Hobby King 25A ESCs, and they seemed to calibrate, but the copter constantly lurched in one direction, even from a slow takeoff.  (two legs would lift off the ground first and it took constant stick adjustments to keep it from veering into trees).  Multiple recalibrations/leveling didn't help, and I realized that propellers were still not spinning up in unison.

Tonight I swapped all the ESCs for the yellow ones that come with the 3DR kit.  When I calibrate them manually, I don't get the audible signals (two beeps) that should let me know they've calibrated, but they seem to work individually.  When I plug them into my purple APM2, I get nothing.

I've confirmed in the mission planner that the throttle is on channel 3 and is not reversed.  I'm definitely in stabilize mode.  Any suggestions on what I'm missing?  I just want to get this thing up in the air!  Thanks for all suggestions.

Santini: follow the instructions. You only need one resistor for full-battery measurement.
