1. Operating Instructions ELECTRONIC SPEED CONTROL Thank you for purchasing the EVX Marine speed control The Marine EVX speed control requires some special care during installation to protect it from water Also provisions for water cooling must be fabricated Since most installations will be custom these instructions will provide some general guidelines to assist in proper mounting and setup The EVX Marine may be used as a direct replacement in the Traxxas Villain EX Installation Instructions The EVX Marine should be installed in a watertight compartment inside the boat The EVX Marine speed control is NOT waterproof It is NOT designed to be submerged in water The EVX Marine speed control can be seriously damaged if it is allowed to get wet If your boat hull does not have provisions for a sealed compartment consider fabricating one from a small Tupperware or Rubbermaid container If possible install the receiver in the sealed compartment with the speed control A template is provided to cut out the hole for the speed control wiring gasket Make sure to seal any screw holes and the water line 37mm entry and exit points with oe silicone sealer Use ample E Wiring Gasket silicone grease around the Template wiring gasket to provide a serviceable seal Traxxas has the following parts available from the Villain EX that can assist you in sealing a custom fabricated radio box 1574 Antenna boot rubber 1 on2. 0 timing will draw excess current in reverse causing the speed control to overheat and premature motor wear e Motor capacitors required Three 0 1uF 50V ceramic capacitors should be properly installed on every motor to prevent radio interference No reverse voltage The speed control is not protected against reverse polarity voltage If changing the battery and or motor be sure to install the same type of connectors to avoid damage to the speed control Removing the battery connectors on the speed control or using the same gender connectors on the speed control will void the EVX warranty Do not let the transistor tabs touch Never allow the three separate transistor banks to touch each other or any exposed metal This will create a short circuit and damage the speed control Insulate the wires Always insulate exposed wiring with heat shrink tubing to prevent short circuits Do not use electrically conductive heat sink compound on the heat exchanger The transistor tabs must remain electrically isolated Transmitter Adjustment TQ Before attempting to program your EVX it is important to make sure that your transmitter is properly adjusted set back to the factory defaults Otherwise you may not get the best performance from your speed control The transmitter should be adjusted as follows 1 Where applicable set the Throttle Neutral switch to the 70 30 setting This adjusts the transmitter s throttle trigger thro
