I wasn't aware that they had the center left stick mod available. Atleast I know it can be done. With the Pershing I am less concerned with this as it will not be one of my main battle tanks, just a fun toy to play with. I have the momentum chips in both my Panther and tiger MBT's so I'm used to the tank not starting or stopping on a dime. I liked the idea of being able to set the throttle and let the tank creep along on it's own but this is kinda scary witha 1000.00 $ plus highly upgraded Tamiya Panther. My biggest concern is will you be able to use the 5th channel toggle switch for the guns, like you do when you add the fire control buttons to the futaba Skysport radios. <div> You may need to replace the toggle with a momentary toggle switch, which is not that big of a deal. It all depends on how the trims are wired on this radio.</div>
