Which radio is the best for Tamiya 1/14 trucks?

[JonBailey]

Will a 4-channel Futaba work with a Tamiya King Hauler turned into a modified Bruder cement mixer?

I plan on having the Tamiya MFCU installed to boot.

How many servos will I need? Are ball bearing servos recommended?

The thing is I will also need provisions to control the cement barrel speed and rotational direction.

The cement barrel will have a separate motor driving it in place of the stock Bruder hand crank.

Can the MFCU control with a 4-channel radio handle the functionality of special-purpose truck bodies as dump bodies and concrete mixing units?

Here is a video link of a cement mixer controlled remotely on a Tamiya chassis:
