It's says "NiCd only" because they don't want you to use alkalines, but they haven't kept up with the rimes to include NiMh and lipo etc.

Personally I'd run a 1/4 scale servo. The two you linked still have alot of torque and either should be plenty. Also I don't care how big the gears are, there's no way they can be as big as a 1/4 scales, it's physically impossible. And what about the gears in the JR is big, the teeth, dia, width? Usually what happens in standard servos is the gears get wider to increase the contact area of the gears making them stronger. Even though the standard has more torque than the 1/4 scale, the 1/4 has stronger gears so it can stand up to the shock loads that get past the servo saver.

makes sense. thanks for the advice.

So I was thinking...you aren't going to be able to run mechanical brakes that way you have it now. The brake pads ride on 50024 and 50074 which is connected to the D gear on the outside of the gearplate 50011. You have all that removed in order to run a pinion / spur to the center diff...which seems like the best idea.

In this picture the upper gear mounting plate is turned around to face the side that the pipe is normally on.

I think you are going to have to rely on ESC brakes...
