3 or 4 channel radio

Saw this 4 channel radio on eBay and rc4wd..

Is this a good radio to control the tamiya 3 speed trans. I see it has a 3 position switch on the 3rd and 4th channel. That sounds like it would control the shifting much better than trying to hold a stick in the position you want.


Are there other radios that offer this kind of gear shift channel control ?


Thanks
