Suggestions for future

Here’s some things that we should (probably) do in the future

CRSF instead of SBUS for RC

Using CRSF instead of SBUS means that we can’t use the RCIN port, but instead connect to a serial port (TELEM 1/2/3/4).

This gives us a few advantages, the biggest one being redundant telemetry over RC link. We noticed often that the RC Link was more reliable than the airport link, and having the ability to get telemetry back from ardupilot and running a Yappu script means that if our airport link goes down (more likely than RC), we still have the ability to view telemetry and fly the drone (especially verifying things like correct flight mode - RTL).

True diversity or PA/LNA Equipped RX

A receiver with a PA/LNA will have more telemetry output power (up to 1W), meaning that it’s less likely for airport LQ to degrade (especially since airport is 90% Air → Ground). It is common to run TX modules as RX for airport.

Diversity receivers help protect against null zones and interference that may be caused by the angle/position/rotation of the drone. Highly recommended and not significantly more expensive than existing RX’s.
