Gotya!

Decent spec and with plastic top & bottom so reduces cost whilst still retaining the heat dissipation from the CNC centre section.

The aluminum center section also doesn't have a milled top for the gears and bearings rather the gearbox is a two piece plastic affair with the lower half sitting atop the aluminum part and then the top cap going over that. The center section is probably an extrusion with fins milled into the outside rather than milled from billet. I imagine that also further reduces costs. A nice side effect is that it also gives you easy access to the internal wiring if you prefer to glue the solder joints down with electronics silicone as these servos do not come from the factory with silicone applied to the solder joints on the internal leads.

EDIT it does however have bearings for the midgears and wedding cake gear in addition to the main output gear so 5 bearings total but I'm not convinced that's actually better than brass bushings which I feel are more rugged than micro bearings. I think I'd prefer brass bushings and 3mm pins on the midgear and wedding cake gear.

Probably not, which is yet another reason why not to run such monstrous servos in 1/8th rigs. 😅

To be safe, the servo would require it's own separate power source.

At 6v, it would be fine with my MMX. 👍

I put a 14000uf 16v cap pack on mine and that solved the momentary voltage sags. The voltage would briefly drop by around 0.3v~0.4v when the servo was loaded up, though I had to actually stall the wheels to make that happen (and I'm using a lee spring) . Under normal conditions it was fine but I figured it couldn't hurt.

I think servos these days are pretty efficient and draw impressively low currents. It's only when they get loaded up that that problems can occur with the BEC getting damaged on our ESC's.

I can't imagine 8 amps going through a typical servo cable for very long, let alone a typical receiver.

At 1/8th scale, it still pays dividends to keep builds as light as possible. The less clutter and cleaner a chassis is (ie the less ancillary stuff) the better a rig performs - better acceleration, faster cornering speeds, better bump handling, greater air control and lower polar moment of inertia for quicker changes of direction/response.

All of above things are desirable for basher rigs as much as they are racers.
