This cross-mixer (also called X-mixer) is used for model submarines with X-rudder (such as type 212) when using pitch controllers not featuring an integrated mixer (such as DoublePitchController LRD, no. 1572).
Can also be used for model tanks.
Easy installation. Just plug 2 wires into corresponding channels of receiver and connect both servos (or pitch controller) to the mixer.
Extremely compact - only measures about 3 x 15 x 22 mm!
