X-Twin Acrobat elevator actuator controlled via an old Walkera servo board from a WK03-02 (4#3B) servo. First step towards the 2.4Ghz brushless X-Twin.

Actuator: 50 Ohm
SMD Pot on the servo board: 5 kOhm (for centering)
Actuator soldered to the servo motor output

PicooZ Pluto (Havoc) actuators controlled by servoboards and the Walkera 2406 Rx (2.4GHz). Centering magnets used. Second vid down is a little flight demo.
