help to build my first quadcopter

[tanmoy35]

I am using
X525 frame
Kk2.2 board
Flysky th9x transmitter receiver
Sunny angel 980kv motors
Everything is set....when I callibrated the esc only 2 motors of opposite direction works....i ain't understanding what the problem is...can any one help...

[akhilzid]

how did you calibrated?
esc direct connected to rx or through kk board?

[satyagupta]

you mean only 2 motors rotate or 2 rotate first and 2 later?

[tanmoy35]

Calibrated through kk board

[tanmoy35]

I have set the system In x quad manner on only 1st and 3rd motors are rotating

[akhilzid]

is the other motors running while increasing throttle?
if not check your esc to motor connection,

[tanmoy35]

Yes the other 2  motors are working fine

[satyagupta]

Your answers are helping others to help you.

The 2 motors out of 4 are working right?
The other 2 motors they dont work at all or they work but slow compared to other motors? Meaning they start spinning late?

[tanmoy35]

2 motors don't work at all . Other two are well calibrated

[tanmoy35]

Satya da I brught all the parts through ur website order no.201409060....posted a mail about esc and motor today itself

[satyagupta]

Can you check the ESC soldering and connection once again? its not possible that 2 of the ESC are not working at all.

[tanmoy35]

I tried connecting working motor with non working esc and non working esc with with working motor then none of the motor works

[akhilzid]

try checking each esc direct connected to rx

[satyagupta]

Can you check the ESC connections i.e the soldering again? may be the soldering or the joints are not perfect.

[tanmoy35]

I soldered the whole setup all again....and tried different esc with different motors...conclusion esc all r fine but 2 motors just vibrate and get heated up very fast

[satyagupta]

check the connection between the ESC and the motors. Motors vibrating means out of 3 wires only 2 or 1 is connected.

Tried soldering it but same prob
