just to throw my two cents into the mix. I was skeptical about spending that much on a powerbox so I picked up a good used one for a jet I am building. Once I started playing with all the features that it has..this thing is wonderful. The redundancy between receivers is amazing, the servo matching is great, add the gps unit and a telemetry unit and you are getting all your relevant data on the screen for you to see. I like it so much that I just bought a competition to use in another airplane of mine. I did not need the gyro, gear sequencing, or the gps that the Royal has, but it does do the servo matching and dual redundancy on the RX's for an expensive airplane. Also this allows me to now use telemetry through the Futaba RX for this plane.
