| Alan, whilst it may be possible to do what you say you are then stuck with your controller only being capable of doing either one thing or another. So with a tank for instance you would have to stop to rotate the turret.
I am sure that you would very quickly become frustrated with this setup, and lets face it the only reason this type of thing is used with the cheap R/C tanks is because they are cheap, and with the cost of three or four channel sets still being relatively cheap nowadays I wouldn't hestitate to go out and get a radio that will do the job properly.
Even a six channel Hitec or Futaba wouldn't set you back much more than 100-150 pounds so it's just not worth the hassle and you will end up being frustrated with your model if you don't.
Bear in mind of course that if you buy such a radio you should be able to use it for more than one model with the addition of some receivers and servo's so it is money well spent.
I actually have a three channel Hitec that I use for four models now, just change the crystals and away I go.
