Driver:
Nic Case
Location:
Southern
California
Car:
A
Schumacher Mi-3
was used as the
base of this
car. The
wheelbase was
modified (mostly
to have more
room for
equipment) to
550mm & the
width was
narrowed 25mm.
The Mi-3 is
great platform
to build from
because it was
able to
accommodate
6mm wide belts &
is very strong,
efficient &
tunable. By
using
belts, torques
from the motor
dose not affect
the direction of
the
car
during
acceleration &
deceleration.
Batteries:
The batteries
are
FlightPower EVO
30’s.
Two, 6 cell
packs
are
plugged together
in series, to be
used as a 12
cell powerhouse.
These
packs
are high quality
& able to
discharge at
over 200 amps!
Motor:
A
Neu 1521 1y
was the motor
of choice. The
Kv n this baby
is
1577,
has a 5mm shaft
& it’s
calculated that
it produces
somewhere
between
8 and 11
Horsepower.
ESC:
The ESC is a
Castle Creations
Phoenix HV-110.
I like it
because
it’s
easy to set-up
and has a great
customer
service. It
handles the 12s
set-up,
is very easy to
program & has a
very smooth
braking routine.
ESC settings
Zero timing, 40%
super slow
brake.
Gearing:
75 x 40
Radio Gear:
The
radio I used is
the
Futaba 3PJ with
the FASST 2.4
GHz
module.
During my
testing, I have
not tried any
radio that had
more range than
this
piece of
technology from
Futaba. Radio
settings = F-
ATV 74% B –
ATV
78%
Gyro:
Futaba GY240
helps the car
sow down in a
strait line.
Body:
The body was
custom made,
inspired by the
JCB DieselMax.
Tires:
The tires are
also custom
made. The wheels
are cnc machined
by
RC4WD.
The tire
compound is a
vulcanized
natural rubber.
Car Setup:
I used spools
front and rear.
Schumacher
yellow springs
150wt oil rear.
