Aura/General Connections and Power
Contents
Step 5 - Aura Connections
After mounting the Aura, 3 types of connections must be made to the Aura:
- Receiver Connections
- Servo Connections
- Power Connections
For the QQ Yak 54 35cc, we recommend using a full-range receiver with a modern Digital Connection rather than traditional PWM Servo Connections.
- Using a modern digital receiver connection gives the Aura access to precise data of each channel for additional gyro enabled outputs, simplifies wiring, and allows for more advanced features. If you are connecting your Receiver to Aura via a modern Digital Connection, continue to Step 5.1.A.
- The QQ Yak 54 35cc and Aura can be used with a traditional PWM Servo Connection from a standard receiver, but it requires Y-Harnessing the Ailerons and loses the capability turn off the gyro during flight or scale gains. If you are connecting your Receiver to the Aura via traditional PWM Servo Connections, continue to Step 5.1.B.
Step 5.1.A - Modern Digital Receiver Connections
A modern Digital Connection is Spektrum SRXL, Futaba S.Bus, Graupner Hott SUMD, JR Mode B, etc. A single Male-to-Male servo extension is connected between the Digital Port on your Receiver and 'Port B' on the Aura as shown below.
Some examples of modern Digital Receivers are:
- For Spektrum SRXL, we suggest receivers such as AR8010T, AR9030T, AR9020, AR12020, or AR12120. See the Spektrum Use Notes for Additional Details
- For Futaba S.Bus, we have test our own R2008SB (S-FHSS), R6303SB (FASST), and R7008SB (FASSTEST), but expect any any S.Bus receiver to work. See the Futaba Use Notes for Additional Details
- For Graupner Hott SUMD, we have tested GR12L and GR16 receivers. See the Graupner Use Notes for Additional Details
- JR Mode B, Taranis S.Bus, and some Jeti UDI digital systems have been successfully implemented. See the Jeti Use Notes for Additional Details
If you are using a modern Digital Receiver Connection to Aura (SRXL, S.Bus, Graupner Hott, JR Mode B), wire the servos as shown below:
Step 5.1.B - Traditional PWM Servo Connections
A traditional PWM Servo Connection is made using 4 Male-to-Male Servo extensions from the Receiver to the Aura Ports. Connect the Aura to the Receiver and Servos as shown below.
Step 5.2 - Power Connections
As detailed in the QQ Yak 54 35cc Manual, we recommended using two batteries for redundancy with the QQ Yak 54 35cc.
- Battery #1 is connected to an unused port on the Aura such as Port S1.
- Battery #2 is connected to an unused port on the Receiver such as the BATT Port.
- This setup provides two independent sources of power to the Aura and the Receiver.
- High Quality Switches can be used between Battery #1 and the Aura, as well as Battery #2 and the Receiver.
We also strongly recommended use an additional 2-Wire Male-to-Male extension between an unused Aura port such as Port S8 and an unused Receiver Port.
- This provides a redundant path of current between the Aura and Receiver.
Power Tips:
- For Gas Setups, Battery #3 will act as the Ignition battery. For Electric Setups, the Battery #3 will power the Motor.
- Always used matched batteries (Voltage, Capacity, C Rating, Quality, etc) between Battery #1 and Battery #2.
- Always DOUBLE CHECK THE POLARITIES on the battery connections as plugging batteries in backward can destroy the Aura or Receiver!
