After some quick googling, it seems the 5 wire servo lacks the controller board inside. 2 wires go to the motor and 3 wires go to the potentiometer. So you could effectively take a 3 wire servo, gut it and solder in the 5 leads like a 5 wire servo. Then it relies on whatever the "controller" is in the receiver to do the work.
For my micro-t, I accidentally fried the stupid main board when a brushed motor back into it. I had the 2.4ghz brushed/brushless, 5-lead/3-lead servo board. I pinched 2 of the 3 motor wires and shorted them on each other and smoked it when I turned it on. Of course, this was after they stopped making them and buying a replacement was $100+ on ebay... This was when I was re-installing the brushed motor back in it because the brushless was too low on torque and too high on speed to be useful in my house. So my micro-t was effectively dead.
I had a spare knock off micro spektrum receiver and found a cheap brushed esc that after mangling it a bit, removing the case off the receiver, making a few holes in the DT chassis, I was able to fit both the esc and receiver in the battery bay area along with the 3-wire servo lead I was already using. I just velcro the 2S battery to the top of the chassis where the original board used to go.

Similar receiver to use with my DX5C radio:

It's not as smooth to accelerate as the original 2.4ghz board was, but it's not bad.
Receiver and esc in the battery area:
I used a jst connector instead of whatever it was on the motor:
Also had the high roller body which is partly why I have room for the battery pack to sit on the upper deck as I had converted my micro-t to a micro-high roller a few years prior when stuff was still available:
I used the original high roller front body mount and made something out of a bit of plastic for the rear body mount.
