Standard PWM Receiver Connection

When using a standard PWM receiver, A3 Super 4 has 7 input channels in which at least one channel should be connected to the receiver in Aileron (A)Elevator (E) and Rudder (R), or the gyro will enter the receiver timeout mode (Red Slow Flashing). [Serial RX/M] is used for flight mode switching, use a 3-position switch of the transmitter to switch the flight mode during flight. [G] is used for remote master gain control, a slide lever or a switch of the transmitter can be used to tune or change the master gain during flight. Connect the ESC or the throttle servo to the receiver directly without passing through the gyro.

Single-line Receiver Connection

A3 Super 4 supports PPM and multi-protocol digital serial receivers which allows you to connect the receiver to the gyro with one single wire on the slot [Serial RX/M]. When using single-line receivers, 2 auxiliary pass-through channels (AUX1 and AUX2) are available which can be used to output the expected channels of the receiver directly. By default, AUX1 is always assigned to Throttle and applies to OUT5, while AUX2 is disabled. Depending upon the receiver type selected, The gyro uses the preset channel assignment to recognize the channels from the receiver. Refer to the table below and check if your radio transmits the channels in the correct order. After each time you have changed the receiver type the current channel settings will be reset to the default. Choose "None" for those channels you do not use.

Notes to buyers

PNP (Plug and Play) – Motor, servos and ESCs are installed on the plane. Additional radio system, battery and charger are required in order to fly the plane

KIT – Package does not contain any electronics such as motor, servos, ESCs and radio but the plane itself. KIT package from different manufacturer has different level of completeness

RTF (Ready to fly) – Package includes everything you need to fly with all the electronics installed such as receiver and battery (uncharged). Batteries for transmitter and basic installation of plane parts are required.

KIT+ (KIT Plus) – KIT package plus some specific parts, KIT + Motor + Propeller etc. The specific parts will be place in the same shipping package but they may not be installed.
