Aura/LargeAircraftInstall
Notes Regarding Spektrum Installations 50cc and Larger Applications (also applies to Turbine Jets)
Flex Innovations has done extensive testing using 2 Spektrum Brand DSMX Remote Receivers attached directly to Aura (A+B Diversity) in several 50-70cc aircraft. Our testing has always been successful and completely without issue.
However, after reviewing the overall situation and experience in the field and noting variations in:
- Installations by users (location, orientation, and path)
- Differences in power system components and configuration
- Different flying styles (distance) and environment of flying site.
- Airplane material (composite/carbon) and complexity (smoke pump, canisters)
- Remote Receiver connection cable/connector fatigue/vulnerability particularly in high vibration environments and long term use
- Variations in transmitter generations and output/data quality
We have opted NOT to ‘suggest’ this installation to our customer in 50cc and larger aircaft and instead suggest an install with more redundancy in this application.
From our experience we suggest*:
A conservative Spektrum install in a 50cc to 70cc aircraft with Aura would include one of following ‘SRXL’ (X-Plus) capable receivers with 3 or 4 remote receiver/antenna and with 2-3 cables providing power to Aura.
- AR12120 (12 Channel Power Safe)
- AR12020 (12 Channel conventional power)
- AR9020 (9 Channel conventional power)
Connect the throttle servo to the Spektrum Receiver rather than Aura.
Further radio setup/install tips based on our experience:
- Do not attach ignition power leads to your receiver or Aura bus. Power the ignition independently of the receiver and Aura.
- Inspect your ignition components carefully and replace if shielding shows any sign of breaking down.
- Route antenna and remote Rx cables far away from ignition components to reduce the chance of nose getting directly into the communications cables.
*It is up to the user in consult with their radio manufacturer to decide what installation they are comfortable with in their model. Flex Innovations does not specify/endorse radio components.
