This is a system for drop seeds or any other kind of small balls from a bottle of water as a deposit.

Is designed for use in any drone with a free channel output to connect the servo.

Works with any "mini" servo:

For aerial vehicles we recommend digital servos because the digital circuit filters the noise producing less movements reducing battery consumption and extending flight time.
Also since the motor will be in contact with dust will be better to use metal gears.

So the best quality/price servo that we recomend is this one:
