I use a Futaba Skysport 4 with mine (and all my other Tamiyas, until the latest project that needed 7 channels then went with the Futaba 7C), the Skysport 4 is a pretty good basic Tx, if you can still get them

To be honest though, I very rarely have the gun stabalizer switched on on mine because it doesn't look prototypicle enough, it would be OK if you only ever went up and down smooth long inclines etc, but over rough terrain at this scale its too sensative and is bobbing up and down all the time, looks like a Darlek
