Yea Deeforce is the place. basically the radio comes with 16 stock channels and you can expand to get 28. So if you remove channel 16 you switch it to 4 more channels and now you have 19 Channels. Remove channel 15 and now you have 22 channels. The 11bpx that i'm using in this Diamond has 3 xbus outputs which can be 3 x bus channels or 6 xbus channels or 12 x but channels. The 16 bpx I used in the F18 Build is completely open xbus/pwm. A couple years ago I didn't understand it all but once I wrapped my head around how the Bus Systems work i love the simplicity of it.

Just look at our turbines now. They too are using a bus system so one cable from the data box (ECU or DRM) to the turbine and done.

Love this advancement in technology!
