that 16 or 24 channels that work as well with a simple R3 the reason most used to used 2 r3 and 1 more r3 as the switch....for the CB200/400 or any additional Jeti Switch (if it has a magnet switch it can be control by a R3)

One different thing about Jeti is......you can actually control proportionally ALL Servo's meaning all channel with a single stick or switch (of course thats not practical but demonstrate the flexibility of the system)
