MultiWii

Hi,
I have:
esc mr.rc simon series 30A
motor 1000kv
arduino uno or arduino mega with multiwii 2.4
gy521
turnigy 5x (5ch) without way for change endpoint (only change with trimmer)

I properrly calibrate the ESCs one to one.
by the GUI multiwii I can see that the range of throttle are (950->1100) - (1800->1900).
In the config.h I set up
#define MINCOMMAND 1000
#define MINTHROTTLE 1064
#define MAXTHROTTLE 1850

In the MultiWii.h I set up
#define MINCHECK 1000
#define MAXCHECK 1900

My problems are:
- If uncomment #define ESC_CALIB_CANNOT_FLY and start arduino the escs make the sound like if the throttle is not in bottom position. Where is the correct procedure?
- Without #define ESC_CALIB_CANNOT_FLY and start arduino the escs make the sound like if the throttle is not in bottom position. If I will restart arduino board without disconnect the lipo battery from escs, the escs start correctly but the motors aren't arm. I use aux1 for arm the motors. In this way the motors spin, the rpm change if I give more throttle or I move the imu. but they have a high speed if the throttle is in the bottom position. Where is the corretc setup of config.h and multiwii.h?
- If uncomment #define MOTOR_STOP the motor not stop. There is caused by the previous problem?

Sorry for my bad English.
thanks.

signals from the receiver going into your FC should be in the range of >1000 up to <2000.
MWii detects values below 980 (not sure about correct trip point) and discards anything below with result of no valid input.
