Hi,
   I am new to the rc world. i started building a tricopter. i have calibrated all the escs one by one by my flysky ct-6 transmitter.
then i uploaded the tricopter firmware on to the kk board(black).
I made all the connections right.
left front motor - M1
right front motor - M2
tail motor - M3
tail servo - M4
aileron, elevator, throttle and rudder to the respected pins on the kkboard 
now the problem is that when I power the board, the blue led flashes once and then permanently stays on. and just two of the ecs beeps after 1-2 sec. no response from the transmitter, no arming.
I tried everything i could. quite frustrated now 
please help.. 

.

Try to upload photos and videos of the problem.......
It will help everyone to understand properly.
