Hi London Image,
The TCB doesn't really care what transmitter you're using, or even have any way of knowing. All it really needs is the correct signal to be sent by the receiver.
I've not used the Paladin but it claims to support PPM, iBus and SBus, all of which the TCB can read. I did a cursory search for documentation on how to activate these modes and it's very sparse, but hopefully you have a manual.
I did see somewhere that supposedly on the transmitter there is a receiver setup screen, and in there should be where you select the protocol. Supposedly if you set it to PPM the PPM signal will then come out of the channel 1 position of your receiver - so that's what you'd connect to the TCB. I couldn't see where the signal is supposed to come from when you set it to either iBus or SBus, but maybe that depends on the receiver.
Anyway, this is what you will need to research, and figure out how to get the receiver to spit out your desired protocol, and then make sure it's connected to the correct pins on the TCB.
