Hello, I'm working in my first Quad X , but after resolve a few issues like calibrate the ACC, my TX and all that stuff finally i can arm the Quad, The problem is when i arm it the motors start in a high velocity,
i have been changing the MINTHROTTLE, MAXTHROTTLE AND MINCOMMAND without results, the behaivor still the same, i think that is a programming issue or maybe my Tx/Rx is failing, im working with this:
My Min and Max throttle that i see in the Multiwii GUI are these:
Min= 990
Max= 1964
So, These are the parameters that i'm using in the program:
#define MINTHROTTLE 1000
#defineMAXTHROTTLE 1900
#defineMINCOMMAND 900
Components:
Turnigy 30A ESC's
Turnigy 2200KV Motors (D2826/6)
Nano-tech 3.3 li-po battery
HK-T6A V2 Tx/Rx
MultiWii 328p Flight Controller w/FTDI & DSM2 Port
I hope that someone can help me, Thanks : )
Motors Start in high speed
Re: Motors Start in high speed
Set minthrottle to 1064.
Macthrottle to 1950 and mincommand to 1000. The calibrate ESC's with these settings and you're good to go.

Hello all ..
I too am having this same issue .. I have completed my quad copter and when I move the throttle up I get a very high IDLE, almost to the point it start to lift off . I have tried numerous time to adjusting the min and max throttle settings with no luck . On some settings the motors become very squarely on starts . The interesting thing is if i bypass the multiwii FC and go directly to the receiver with the ESC it works perfectly . I get a very nice idle start and full range of speed.. I did try and use the config to set the ESC range and it did not help . I'm suspecting the ESC's but at this point I'll try anything .
Thoughts ??

Try calibrating the ESC's one at a time directly from the Receiver Throttle channel.

Re: Motors Start in high speed
On the GUI there is an option for setting the minimum for throttle. Try to modify that value
