Just ordered a tunity 9x RC system even though I actually would be glad to skip it and just use GCS or other computer/phone based solution.
However, while pipX will work good for telemetry it may not be suitable for direct control in all environments. (Interference and such things)
So I thought. The pipX is based on the ARM processor like all the other openpilot components. It should have more power than needed for handling its own communication. If you just make sure some PWM outputs are available on the pcb you can use it to control a RC-transmitter. That way the PipX can take data from the GCS and seperate control commands from telemetry and push it into a standard rc transmitter module.
What do you think?
I attach a small picture of my imaginary setup.
