FlySky FS-i6S transmitter and receiver set
Perfect for the CLARK TK boards as the boards were built with this radio.
Setup is straight forward and is described in detail on Clark's website.
S-Bus capable, and we highly recommend getting the TK boards with S-bus feature as it:
reduces the receiver wires to just one
driving and control protocol is so much easier to drive, just like stock HL controls. and the 32 bit vs 16 bit gives control more resolution.
Model memories up to 15
comes with 1 receiver (6 channel) but with the S-Bus variant of the TK40S / TK60S / TK80S, you just need the 6 channel RX and it'll work perfectly fine.
