I have a Dji W-km on 450 flame wheel axi 2814/22 motor and MGM compro A 40 esc using 4cell batt. DX7 tx. My problem is everytime i start the motor the idle speed is too fast that i have to tie down the quad on the ground, or it will fly right-away and dont know where it may stop ascending :( i updated the new firmware with idle speed (new from dji) but still not working...i tried to run one motor not connected to dji wkm and it run smooth with idle speed controled by my input...I NEED HELP IF ANYONE CAN GIVE ME ANY SOLUTION TO THIS PROBLEM...i love the new s800 but i need to fly my quad first..hu huh uh huu hu ...

AXI 2814/22 and wich propellers?
What is the weigh for your 450?
What is the motor idle speed (setup program)?

Axi 2814/22 is powerfull try it with 3S Lipo and tell us more about your setup.

I program each esc (page 2 table 1)(http://mgm-compro.com/manuals/en-man...d120608-02.pdf) except i change brake to off..anyway i tried one motor again...pull the control wire from dji MC and put back the red wire and connect it to Rx throttle.. and it runs ok with low speed to high speed on tx input...but again same problem when i put it back in dji MC motor turns fast on start...thank you very much for responding...(kloner)...hope to hear more from you...

nisouck <<<apc 12x6 but i changed it with 10x4.7 hoping to see it even just to hover for 1minute :) but no luck....flame wheel 450 whole thing attached..it weigh between 2.5 to 3lbs. Idk how to say it in details but when i start the motor (CSC) motor turns on high rpm, like 40% of its motor speed.

Im sorry but im new to this rc multirotor hope you guys understand...i'll try not to quit and keep on researching and learn. Or worse thing is i'll just give my quad to the hobby shopand let them set it up ....lol.. but not yet ...wify still pushing me to fix it....so thanks guys if you have any solution on my motor speed problem , i really appreciate it if you could share it to me...

Guys, i tried so hard for my quad to work but its just that the motor is really strong on f450..it doesnt work, its a flying desaster...solution: change to smaller motor...thanks for all the advice,, ill try f550 dji motors and dji opto, dji -wkm...if i still fail? thats it for me, ill just stick on rc helicopter... :(
