Mayatech HV6535 35KG V4 Servo with Drop Release Mechanism

A ready-to-mount payload release for drones and RC aircraft: a Mayatech HV6535 35KG V4 digital servo already fitted to a CNC-machined aluminium single-slot drop bracket. Flick a switch on your radio and the servo pulls the sliding pin to let the load go, which suits bait drops, rescue lines, marker releases and delivery trials.

Key features

• HV6535 digital servo, V4 revision, rated for 6–8.4 V, so it runs directly from a 2S supply or a high-voltage BEC
• Single-slot sliding-pin release driven through a 25T metal servo arm
• CNC-machined aluminium bracket with mounting holes and slots for fixing to an arm, plate or landing gear
• Operated from any spare servo channel on your receiver or a flight controller servo output
• Blue servo with a silver bracket, supplied as one assembled unit

Before the first flight, set the servo end points in your radio or flight controller so the pin opens and closes fully without the mechanism binding; a stalled servo draws high current and heats up. The servo is rated 6–8.4 V, so power it from a suitable BEC rather than a 5 V flight controller rail.
