This board is the same physical size as all other eMAX timers. The pins are close to the microcontroller chip,making for a very thin installation. The Servo is on the bottom and the ESC the top. Same orientation as our other timers. This configuration is very thin top to bottom with the wires connected. The pins face toward the front of your fuselage.  You will note the place for the RDT pigtail (optional) as well as a remote start switch connector (optional).
