    Installed the hml350 pro automatic landing gear. When the gear is in the down posision the servos are humming a little. Is that right.

    Sounds like they need to be adjusted. The servos probly shouldn't be powering/humming in the down position because that would eat up battery like crazy and burn up the servos
