VTOLkarthik

Throttle_min was in d mid so reduced it to zero but stil not able to arm...

I reduced throttle end point from 100(default) to around 70 or so motor spinned without arming but stoped.. No response nw...

can you see "ARMED" message in mission planner as in your replay 190 or Red Solid LED In APM?


VTOLkarthik

Yesterday I was not anle to do it... Will check it today n wil let u knw...

VTOLkarthik

wen I connect to PC and run the motors through the Tx all the motors run at different time, guess it can be corrected by trims..
But if I remove the USB cable it doesnt  get armed!

Need help..!

Guys its working! I hav no idea hw but it is!!! Maybe I elevated the gps...

But I hav one small prob, all motors run at around 10% except motor 4 which runs like at 20%  or more...
should I have to trim or is thr any prob?

The reason is because the apm was tilted to one side since I had put foam in the bottom as the vibration dampner...
I removed but d apm sits little towards left like in d pic...

Do another esc calibration, for the motor problem if that doesn't work , just reset all parameters ND do the calibration again

VTOLkarthik

Twice I did esc calibration, dint work..
ill do the whole thing once again with apm mounted on the quad..
btw how to erase d eeprom?

Immanuel

Go to the all parameters section of mission planner , on the right u will have the reset all parameters option

VTOLkarthik

Tuk it for a spin and it was really gud!!!
but no video, ill take one if possible..

Hav one issue though..
wen I give throttle and fix it at 60 to 70% it keeps coming down..
but is stable!  :thumbsup:
