You don't need to go to TK 60 to get things off the sticks. TK-22 with a Turnigy 9X works just fine. On our set up left stick controls turret rotation and elevation. Right stick purely for driving. Mg on switch, Main gun on spring switch, lights on switch, engine start up on switch (which controls smoker on off as well. Some guys even pot their volume control.
TK-60 is no more expensive than other boards with more bells and whistles but for me at the price the TK-22's are at they are the best deal in the market as far as I am concerned. Easy to install and program with the remote have enough features for me...
