Wink FS Novak Havoc Spec Brushless System 17.5T 2200kV Mint! Cheap!

Hey Guys

Just sold my TRF201 earlier today and now I have a brushless system I don't need. This Novak brushless system doesn't have a full lipo run on it yet. The price is $120 shipped in the US and the price is firm.

I geared it low and the motor never even got hot to the touch. Here are the specs and details for the brushless system:


FEATURES: Meets ROAR specifications
Rebuildable 540 size motor equipped with sintered rotor for precise
throttle response and high temperature resistance, motor also has
shielded sensor cable
Fully programmable ESC, user-friendly interface with nine adjustable
parameters: Minimum Brake (10 settings from 0-27%), Drag Brake (10
settings from 0-27%), Dead Band (5 settings from 2-6%), Minimum
Drive (5 settings from 1-5%), Throttle Curve (Linear and Expo),
Brake Frequency* (7 settings from 1-8 kHz), Reverse*, Motor
Rotation* & Li-Po Cut-Off (*available only in brushless mode)
Throttle curve allows experimentation with two throttle responses
Linear and Expo which range between a quick burst of power to a
smoother, more controlled low-end power delivery
Thermal Overload Protection circuitry allows ESC to operate only with
the SS-Pro series or other brushless motors with built-in thermal
protection that follow ROAR guidelines
Brake Frequency adjustment contains seven degrees of adjustability
LiPo cut-off circuitry prevents batteries from going below the
critical safety level
Smart Braking II enables "shifting" from forward to reverse
120 day warranty on both components


INCLUDES: Novak Havoc Spec Brushless ESC, 17.5 Turn Brushless Motor with power
capacitor, instructions, double-sided mounting tape


REQUIRES: Installing in model and conncting to battery and receiver
Pinion gear of modeler's choice


SPECS: ESC-
Input Voltage: 2S Li-Po cells or 4-7 NiMH cells (1.2V/cell)
ESC Size: 1.18 x 1.54" (30 x 39.1mm)
System Weight (ESC & motor with wires): 9.59oz (272.0g)
Design: Sensor-based
Motor Limit (brushless): 8.5-turn Novak 540-size sensored motor
Motor Limit (brushed): 27-turn for 540-size motor/12-turn for
550-size motor
On-Resistance (brushless): 0.0012 ohms @ 25°C trans. temp.
BEC: 6.0 volts DC / 1.5 amps
Rated Current: 120 Amps @ 25°C trans. temp
Braking Current: 120 Amps @ 25°C trans. temp.
Status LEDs: 4
Voltage Cut-Off: 6.25V (when Li-Poly Cut-Off Circuitry is enabled)
Power Wires: 14G Super-Flex Copper-Strand Silicone Wire w/Tamiya
Battery Plug
Motor-
Motor Size: 540 Size: 2.08L x 1.41D (52.8 x 35.8 mm)
Motor Magnet: 12.3 mm Sintered, high-strength Neodymium
Motor Watts: 130
Motor Turn: 17.5
Motor KV (unloaded): 2,200
Shaft Diameter: 0.125" (3.2mm) accepts all existing pinion gears
Bearing Size: 1/2 x 3/16" (12.7 x 4.8mm)

The box has one corner crushed where I accidently stepped one it after opening it and removed everything. I will post pictures tomorrow morning sometime.

Feel free to PM questions!
