Idlers ' axles and slots can be in a different, water proof compartment inside the hull. http://www.rctankcombat.com/tanks/T056/022-large.jpg IT is the front compartment that contains the green batteries pack.

The photos are old, during construction. There's also a wooden "fire wall" that separates electronics from batteries and motors. The bearings of the drive wheels can be of the sealed type, coated and sealed with extra thick grease or vaseline.
