i have been building a quad-copter using hk i86l multirotor flight control board. i have done the calibration part, but when i switch on with quad 4+ mode, the blue led won't blink. there are prolonged beeps but the blue led won't glow solid. could someone debug the problem
[Admin Note] Please put a meaningful topic name, and post in the right board. Topic name updated.
throttle is not at lowest at startup
do esc throttle range calibration and make sure that
that when you startup your tx throttle is at its lowest
1.Check for the correct firmware.
2. Check if the throttle or rudder stick needs to be reversed.

@Anwar sir: My apologeze sir. I agree that my topic was very vague and i need to be more specific. I will do the necessary amendments in future. Thank you.
@Saikat: thank you for your post. i did the esc and throttle calibration as per the manual instructions, the blue led was solid, post the throttle calibration. however the esc started beeping with a high frequency. is that right or do i need to make changes.
@RcBharat: I am using a turnigy 9x, mode2. pardon me, but did you mention the firware of the tx, or the multiwii control board. Also i am using a 3s lip0 with 1800 mAh, i knwo the rating is very low, but for startup i thought i would experiment with this battery. Will the low current rating cause a problem.
There is nothing wrong in your battery and your Tx firmware.
Please confirm is it HK i86 or multi wii?
Sir is the pic of the board i am using.
Ok
Check if the throttle and rudder sticks are in the correct way they should be.
The arming procedure is
Put the throttle stick in minimum position and pull the rudder stick to the rightmost position for 5 second.
It should work now.
@RcBharat: Sir, the board got armed and worked. i Need to sync the four motors for a good flight. Thank you for your valuable advice.
Good to hear!!
What was the problem??
the arming of the board sir, that's it :) the throttle was pulled to bottom most position and then to the left as you suggested :) it worked.
Reverse your rudder stick, it should be moved to right not left
Yes sir, i reversed it. Its working :) thank you again
Cool, Have fun!!
