Hi...iam using kk 2.0 flight contrlr brd.it is showing ERROR : NO THROTTLE SIGNAL.wat should I do?

Switch on the Radio first and then switch on the KK board.

Thanks for ur reply..i tried ur suggestion but it remains the same..

Confirm if your receiver is binding/working. If its working properly then turn on your radio first then your multicopter. If still getting error then disconnect power from multicopter and reconnect again. If still getting error then post picture of connection on your KK board.

Try to trim down your throttle  .... may be FC is not getting min throttle

Have you tried moving your sticks left right / right left? It seems like that it is stuck on 'safe' mode and that it is not 'armed". Btw, what Tx/Rx  are you using?

You have to move and hold the right stick (Mode 2 Tx) either to the left or right for a few (5) seconds to disarm it and get out of 'Safe' mode.

Throttle channel are connected elsewhere in receiver. So, kk2 multocopter board not get initially zero throttle initially (eg, rudder,elevators are center positioned and gives 50% position signal during start). Hope you will get it solved early.

Good Luck.
