good write up from Arctic Cat ZRT there

the first release of tk60 was 6ch, then 8ch was added , and now also sbus(10ch) on both the tk60 and tk24 can be had.
since I started carrying Clark stuff ( sell and support, and make soundfiles) the 6ch version is seldom sold these day's . most sbus and 8ch. many also use it with the flysky radio , and that combo gives trouble free and easy setup and usage
No need to do those ninja stick combo actions to trigger cannon/mg/lights etc .
As can be seen here

One wire between receiver and board is also a nice feature
recomend the 'remote' ( to program the different settings on the board ) and if going to have 1 board , swopping between tanks, and want to reprogram the sound , also the pro programer is recomended . Be sure to get the tk60P
so you are able to have that feature without the need to send back ( all boards I sell are the P verson )
Compact size , good sound ( 15 watt onboard amp) also supports the PDSGB type gearbox , good sound library , and more soundsets added.
