NOVAK GOAT 3S - BASIC Setup Manual

transmitter adjustments
If you have any problems with Step 5, adjust transmitter as follows and
then repeat the One-Touch programming in Step 5:
a. Set hIGh atv or Epa to maximum setting. [amount of throw at full throttle]
b. Set low atv, Epa, or atl to maximum setting. [amount of throw at full brakes]
c. Set EXponEntIal to zero setting. [throttle channel linearity]
d. Set thRottlE channEl REv. swItch to either position.
E. Set thRottlE channEl tRIm to middle setting.
[adjusts neutral position/increases or decreases coast brakes]
F. Set ElEctRonIc tRIGGER thRow adJUstmEnt to 50% throttle and
50% brake throw--best for reversible ESCs.
[adjusts trigger throw electronic/digital pistol-grip transmitters]
G. Set mEchanIcal tRIGGER thRow adJUstmEnt to position with 1/2
throttle and 1/2 brake throw.
cooling fan installation
the included novak 30x30x6mm clear cooling fan (novak kit #5648) is
required for the Goat 3s when using a 3-cell li-po pack. In addition, the
fan comes with the connector already on it to match the pins on the Goat 3S.
The Goat 3S ESC features a set of power output pins for running auxiliary cooling
fans, so you can add fans to the motor, the ESC or both, and they will switch on
and off with the ESC's power switch. These pins output 6.0 VDC (same as the
BEC), so you will get maximum output from cooling fans without over powering
them by running directly from the battery pack's voltage.
The pin-out label located on the
Novak
front lower section of the ESC's
#5648
case (under the pins, push button,
installed
& LEDs) shows the polarity of the
power output pins.
The 2 pins on the front edge of
the circuit board--Positive (+) is
on the left, and Negative (–) is on
the right. The set of 3 pins behind
them are for the user-replaceable positive
input signal harness—The polar- fan pin
ity of those is the same: Positive
negative
in the middle, Negative on the
fan pin
pin-out
right, and the extra pin on the
FIGURE 6
label
left is for the input signal.
sensor harness wiring
Should any of the 26G Teflon wires pull out of the connector on the end
of the motor's sensor harness, re-insert them in the appropriate slot in the
connector as shown below. There is a small plastic tab that grabs a small
raised barb on the back of the metal socket crimped onto the Teflon wire's
end. The plastic tab should be checked to make sure it has not deformed
excessively before inserting the metal socket into the plastic connector
housing with the barb toward to plastic tabs.
