I was surprised to see how small that receiver is (battery included inside?).
It made me wonder why the Tactic TTX 404 receiver uses a four "AA" cell battery pack to power it.
I was disappointed that the Tamiya radio did not include the shifter gate. Then I opened the box for the motorized leg support that is supposed to include the steering gate, and it was not there either. I can try to make my own. Where can I get the shift and steering gates for the Attack radio if I can make good accurate ones?

all receivers need a power-source of 5Volt to operate . Therefore the deal with the 4xAA battery packs .
The Tamiya Attack needs that too :
REQUIREMENTS
AA Batteries: Four for transmitter
Receiver Battery: 4.8-6.0V battery pack (do not use dry-cell
batteries as receiver's power source)
but in your case by using the Tamiya MFU , you don't need no extra power on the receiver , since the MFU supplies power to the receiver.
If you would use this radio-system with any other truck , boat or any type of vehicle , which uses a ESC ( electronic speed controller ) and it is one of them which has a BEC ( battery eliminator circuit ) , then you will not need extra power to the receiver either.
since you are new to all of this , you may want to look at these 2 webpages
( even thought I have that posted in my tanker-section , it also applies to the truckers ) ,
explanation about stick modes and other radio system terms :

don't get too confused with these info's , but again , some of that stuff listed there applies to the trucks as well .
