Radio help!!

[tc1cat]

I am in the process of building dozer and I need some help in choosing a radio for it. Both sticks are already used for controlling the dozer. I want to use Firgellis for the blade movement. What radio would you use? I know that it should have at least 1 3 position switch for the Firgellis. I am not sure which models of the various radios have this feature. Firgellis will only lift and lower the blade.

Don't worry guys, this is just in the design stage now. No time has been taken from my making parts for the orders taken.

Thanks in advance,
