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.

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

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

ok im eaily cornfiused the apm1 kitm comes with 4 resitors for voltage detection so do i in stall all 4 resitors/4 pin outs or jut one resitor like in the pic in instructions

Chris,

many thanks, 

gonna do it first thing tomorrow morning.

great news.

Ramesh: Yes, you can do it via the MP. The CLI or MP setup process is just for the flight modes that you're changing via your RC toggle switch.

HELP,

Is it possible to set FLIGHT MODES from MP itself, while reading the text, i felt i could, but towards the end of the text it say u have to go through CLI. I want to avoid doing any changes through the CLI, too scared i might screw up something. the more i work with the quad and APM2 the more i feel i need more modes, and i now want STABLE, HEIGHT HOLD, LOITER, RTL, and day finally FOLLOW ME. so can someone confirm if i could get 6 modes by just MP, or will i have to go through CLI to confirm the PWM figures ???
