ESC for R/C Tank

Hop up options ESC series

SPEED CONTROLLER for 1/35 RC tank

Overview

ESC4 controller uses 4 channels to control R/C tank's forward/backward movement, sharp turning, pivoting, turret rotation and gun barrel evaluation at variable speed Miniature design(30mm X 30mm) for small scale (1/25, 1/35 ,1/48 and etc.) R/C Tank Auto cutoff protects Li-Polymer battery from over discharged Safety shutoff prevents unwanted movement while signal lost Status LED indicates Controller operating status Easy installation Mounting hole in center of controller Auto R/C Control signal detection, support and system High Resolution Mixer

Assembly Guide:

Refer to wiring table shown below, connect ,Rudder(CH1), Throttle(CH2), Gun barrel evaluation (CH3) and Turret Rotating (CH4) to Receiver by preassembled Control Cables. ESC has BEC, no extra receiver battery is needed.

First turn off your transmitter, than connect battery pack via Battery Cable, Red wire of Battery Cable is + pole and Black is - pole. If powering is in good state, Red status LED will be lit.

Turn on your transmitter, Red status LED will be turned off if radio control signal was received correctly by CONTROLLER. If Red status LED is sill On, Check that your transmitter and receiver are operating on the same frequency and check the polarity and integrity of receiver channel signal cable connections. If Red status LED is flickering, that means poor or weak signaling, pull out transmitter antenna or adjust Receiver antenna layout.

At first time installation, repeat previous 2 steps to make sure connection between battery, receiver and controller are stable and correctly, than proceed next steps.

Turn off transmitter and disconnect battery pack form controller, solder preassembled ESC1,ESC2 and ESC4 cable to left, right track and turret rotation driving motors.

Turn on transmitter, than connect battery pack to controller, Red status indicator should be lit on and turned off instantly because controller was powered than receive control signal correctly. Adjust throttle, Rudder and Turret Rotation channel trimmer on transmitter till all motor was stopped and no hum sound was heard.

Keep Rudder channel stick in natural status and move Throttles channel stick forward or backward, the tank should move forward or backwardly. if pivoting occurred, find out the motor which is turning in wrong direction and reverse its motor cable. Adjust Rudder trimmer if tank can not go straight.

FAQ

Build in Mixer: Convert Rudder and Throttle control signal to Left and Right track speed signal.

Safety shutoff: Occurred if controlling signal is lost, controller cuts motor off and waits signal come back, status LED indicator will be lit.

Auto cutoff: The motor cutoff will occurred when battery input drops below minimum supply voltage of controller. If cutoff is happed frequently, increasing battery cell to rise voltage or use battery which has larger output current.

Remote control system: There are two remote control system in market, and , ESC4 can support both.

Voltage booster: Signal level of some receiver may less than 3.3V and can not be detect by ESC4, we will need a simple circuit as follow to boost voltage by 0.7V.

<RX RED> is power of receiver( red wire)

<RX WHITE> is PWM signal from receiver( white wire)

<CSC RED> is power of ESC( red wire)

<CSC WHITE> is boosted PWM signal, connect to ESC4 (white wire)

PRECAUTION

For space saving, ESC have no external housing, please keep Controller form conductor and metal.

Read carefully and fully understand the instructions before commencing assembly.

Not designed for 1/16 and larger scale R/C Tank, please refer to TK series.

Refer to following pictures, parts circled by red frame are power FET and regulator, keep it from any thing for thermal diffusion.
