Before installing product on the multi-rotor, connect power, test & verify several
times the smooth operation of the folding landing gear.

Q&A for possible issue encountered:

Q: When power connected, no reponse.
A: This unit has long power detection time that can be several tens of seconds, later
you can hear the power up by the gear reaction acoustic.

Q: The Extented landing gear could not fold.

If too tight, loosen this screw a little. re-adjust the landing boom leg, unit spacing
and repeated test to confirm the folding/extension actions are smooth.
