I'm having the same problem ~ 1 click and it goes up and one click down and it will go down ~
Hello, multiple causes can be possible, i think :
1 - Wrong calibration of throttle course on the ESCs. Solution : Recalibrate all ESCs.
2 - Too "strong" prop. Solution : Change prop and reduce diameter and/or pitch.
3 - Too "high" motor. Solution : Use a motor with less Kv or use a "lower" battery voltage.
Another solution is to use a throttle curve on the transmitter to "smooth" throttle
like using expo on other commands ...
Get rid of the clicks on your throttle stick ! That's for planes, not for helis or multicopters, these need a smooth throttle stick so you can get it to hoover.
