I would suggest anyone to get a 6 channel radio. The HK T6a is a perfect radio for tanking. The proportional servo control on channels 5 and 6 are great. The channel 5 can be used for independent servo control of the barrel and channel 6 is good for panning the horizon with an FPV camera or proportional turret rotation if you used a continuous servo.

THE BARC is designed to be plug and play with an RX18 to give you the same functionality of an HL tank with Tamiya battling added. Of course it blocks the Hull recoil, adds momentum to give you better esc control of your tank, but that is it's primary purpose. When you start going with independent barrel control, then what ever system you buy means you are advancing past plug and play.

Now with a T6A radio and a Benedini TBS the gloves come off and it can do a lot more, and for this you need the extra channels This radio combined with a BARC4 and Benedini will give you all the functionality you need in a tank. The BARC can be used with a 4 channel for Basic tank control. If you need more then that buy a 6, 9 or whatever you need. As I mentioned I wouldn't go with anything less then 6 channels, and I strongly suggest people opt for radios that have proportional control on channels 5 and 6. There is so much more you can do with them. The T6A is less then $30 from Hobby King. Less then some receivers for other brands.

Clark has built a powerful board for $100. It made no sense for me to develop a competing board at the Clark price point in this market. Chance are I couldn't do it for less, so why bother. Once I found away to hook up the Benedini to the Clark it really cemented the fact it was pointless to develop " Another" board. The TBS hooked up to a Clark is a powerful combo.

I am more then happy with the T6A/BARC/TBS/RX18, and have them in all my tanks. Having multiple brands of boards scattered throughout the fleet, can make it very confusing. The Clarks,El MOD and IBU2 I have purchased have been removed and thrown in a drawer. Not because there is anything wrong them, but only because I am happy with the BARC and the simplicity of the stick commands, and the great sound of the TBS. My tanks are set up exactly the same. Proportional control of the Barrel with a servo on channel 5, turret and throttle through the RX18, and all the auxiliary lighting through the BARC / TBS, and now the BARC control the servo recoil. If I cared about proportional control of the turret I would use the Proportional ch6 and a continuous servo. You do not need anything special for this other then a good radio.

Like you I am very interested in the New TK60. Programmable sound( Benedini like), and a USB connection to build battle tank configuation files will be a dynamite feature. The one knock people seem to have on the Clark board is the IR programming on a remote and the complexity involved. Without that channel guide, I am not sure how much success you would have. The option of selecting battle files off a computer and downloading them into your tank is really intriguing to me.
