Bo, that's very clean installation!
However, I did spot a place where you could save a few grams of weight and also eliminate a couple of connectors from the servo system:
- Connect the long wire coming from the tail directly to the SBUS port of the RX
- Then connect the aileron servos directly to the normal servo ports on the RX
- Finally, connect the telemetry sensor directly to the SBUS2 port of the RX
This way you save the weight of the front SBUS hub and maybe some wire too without losing any functionality. This is what I did in my Spark with the exception that I have only the elevator servos in the tail. I also have a telemetry sensor, a battery current/voltage/fuel gauge which has been very handy.
