HOBBYWING HIGH-VOLTAGE POWER
;ese days, if you’re selling a big monster truck, it better have
big power on tap—and the Colossus doesn’t disappoint. ;e
brushless speed control features thick 12-gauge wire, and you
can adjust functions such as running mode, drag-brake force,
low-voltage-cuto; threshold, start mode, and max brake force,
and that can be done with the small button next to the on/o;
switch; however, you can also alter speed-control settings
through a Hobbywing control box or Wi-Fi module. You also get
heavy-duty XT90 connectors for the batteries and a brushless
fan to keep the speed control cool at all times. ;e brushless
motor connected to the speed control is a 1/8-scale 1450Kv
unit. ;e case has fins that increase its surface area, and that
helps keep operating temps down. ;e motor mount is drilled
and tapped, so you can install a brushless fan to further reduce
the temperature of the motor.
;e center gearbox is a completely sealed unit, and inside you’ll
find a 2.67-inch-diameter steel spur gear, which is attached
to a di;erential. It takes the removal of four screws to take o;
the bottom cover on the housing and gain access to the center
di;. ;e motor mount includes an aluminum housing that adds
support and helps with the dissipation of heat from the motor.
;e di;erential housings use an all-metal multipiece design
and thick grease to control their action. Long front and rear
dogbones connect the center di;erentials to the di;s in the
front and rear housings, while rebuildable universals are used
on all four corners.
;e speed control is a 1/8-scale
unit capable of handling up to
6S power, and it’s coupled with
a 1450Kv brushless motor.
Changes to the settings on
the speed control can be done
through the small button on
the switch or with a Hobbywing
control box or Wi-Fi module.
;e Colossus features a triple-gear-di; drivetrain, and the
housings are all-metal units.
Grease comes in them from the
factory, but it can be removed
and replaced with silicone fluid if
you choose to do any tuning.
