For the advanced scratch builder and speed expert, the Mark 4 controller provides the ultimate in super-sensitivity and response. This championship grade unit is readily identified by its clear ruby-red case and features a specially built 15 OHM resister cartridge (just right for those hot rewound motors). The Cox cartridge employs fine high temperature wire that is size stepped for greater dependability and long life. Dynamic braking, an indispensable feature made famous in the Mark 3, is also featured in the Mark 4. Long-time users of Cox Mark 4 controllers usually comment on the steady acceleration available over the full range of plunger travel and the fact that a Mark 4 outwears three ordinary controllers. All of the outstanding features of the Mark 3 are incorporated in the Mark 4.
This controller outperforms and outsells all others in its
class. The pistol grip handle is comfortable to hold and is amply vented
for rapid heat dissipation. A 25 OHM taper wound resistor permits smooth
acceleration and response. Plunger is thumb actuated and has a
silver-impregnated graphite brush slider for maximum electrical and mechanical
efficiency. Cooling fins on the plunger shaft maximize heat dissipation. A
flexible and easily replaced fuse wire protects the resistor from burnout
resulting from improper hookup. Connecting cable terminates in color coded wire
leads and alligator clips. A flexible cord protector minimizes chafing and wear
of cable where it passed through the controller case.
