Lighter viscosity center diff fluid may increase the tendency for the front tires to be over driven spin faster than the rear tires Over driving the front tires will reduce handling and acceleration authority Only use silicone differential fluid oil in the differentials Traxxas sells a range of oil viscosities see your parts list The differentials have to be removed from the vehicle and disassembled to change replace oil DUAL SERVO STEERING SYSTEM Revo uses dual servo steering and a single heavy duty servo saver for powerful responsive steering To prevent unnecessary receiver battery drain it is important to make sure that the servos are at rest when the steering is at neutral If one servo is out of adjustment then both servos will work against each other fighting to find center Adjusting The Steering System 1 Remove the servo horns and steering links from the servos Disconnect the steering links from the servo saver 2 Adjust both the steering links to be the exact same length 41 8mm use Steering Servo Horn Link Length Template below to set length 3 Switch on the power to the receiver and the transmitter 4 Adjust the steering trim on the transmitter to the neutral 0 position 5 Connect one end of a steering link to the steering servo saver arm and the other end to the servo horn 6 Position the steering servo saver arm perpendicular to the centerline of the vehicle 7 While holding the ste
7. Paint The body supplied with your model is molded from lightweight and durable clear polycarbonate It should be painted on the underside so that the color will not be scratched off while running The best way to paint the body is by using thinned paints sprayed through an airbrush or spray gun If you do not have these tools the next best way is using spray can paints Whatever paint you use be sure that it is made for painting Lexan or polycarbonate Other types of paints and solvents can attack the body material and cause it to appear foggy Preparing the Body The body must be washed thoroughly with dish soap and water to remove any grease or oil i e fingerprints which may keep the paint from adhering to it Dry the body completely with a soft lint free cloth Use the supplied masks to mask the windows Mask off any stripes or custom effects with either masking tape or special tape made for striping This special tape is available from automotive paint supply stores and will provide sharper edges than masking tape For easy custom colored striping automotive pin striping tape can be applied to the inside of the body and painted over Be sure that all of your tape and masks are fully pressed down burnished so that the paint will not run or bleed underneath Usually the darker colors are painted first followed by the lighter colors If your paint scheme would be easier to mask by covering the dark areas and spraying them

9. best engine tuning Do not rely on a temp gauge alone to tune your engine Tune the engine by paying very close attention to how it responds to changes in fuel mixture more smoke less smoke fast sluggish reliable stalling smooth sound muffled sound etc Once the engine is tuned then observe the temperature The temperature gauge can aid you in tuning by giving you a relative indication of how your adjustments are affecting the engine and to help prevent you from reaching excessive engine temperatures For example as you lean the fuel mixture the engine performance will increase along with the temperature If you continue to lean the fuel mixture and the temperature increases but the engine performance does not change then you have exceeded the maximum safe lean setting Make note of the engine temperature Generally try to keep your engine from exceeding 270 F when measured at the glow plug If necessary increase airflow to the engine by cutting out the rear of the body windshield and front valance In some situations the engine may perform very well with no stalling lagging or hesitation at temperatures above 270 F particularly in very hot climates If richening the fuel mixture to bring the temperature down to 270 F results in poor sluggish performance engine never cleans out then return the engine back to a satisfactory state of tune based on how it sounds and performs always with a visible stream of blue smoke coming fro
10. form a precise fit The engine needs to heat up to a temperature around 200 to 215 degrees to allow the piston and sleeve to achieve this fit properly A precise fit between these two components is critical for proper compression and optimum performance If the engine runs too cold during break in the piston and sleeve will not expand to their appropriate sizes for break in and this can lead to premature wear of these components This wear may not become apparent until after winter has past and the engine is operated under warmer running conditions e Warm the engine to approximately room temperature by removing all fuel and storing the vehicle inside at room temperature until just before starting the engine An extremely cold engine can become difficult to start After the engine is running it is important to keep the temperature of the engine up around 200 to 215 degrees during break in In weather below 45 degrees the TRX 3 3 Racing Engine will tend to run at lower temperatures between 160 to 180 degrees when tuned at proper break in mixture settings This is too cool for break in Do not lean the fuel mixture to increase engine temperature This will also decrease lubrication and cause your piston sleeve to wear prematurely e Wrap the cooling head with a paper towel clean rag or sock to help keep the engine running around the recommended 200 to 215 break in temp If too much heat is contained the engine can actually run t
11. ideal setting Never try to tune from the lean side There should always be a light stream of blue smoke coming from the exhaust Before you begin tuning the engine should be warmed up to its normal operating temperature and running slightly rich All final tuning adjustments must be made to the engine at its normal operating temperature You can tell the engine is running rich by noting any of the following e Sluggish acceleration with blue smoke coming from the exhaust e Revo may not shift into second gear e There is unburned fuel spraying from the exhaust tip e Leaning the high speed fuel mixture increases performance High Speed Fuel Mixture Adjustment With the engine warm and running at a rich setting gradually lean the high speed fuel mixture in 1 16 turn increments Make several high speed passes after each adjustment to clear out the engine and note any change in performance The TRX 3 3 is extremely powerful Remember to apply the throttle gradually to prevent wheelies or loss of control Continue this procedure until there is no longer any performance improvement If any one of the following conditions occurs the fuel mixture is already past the maximum safe lean setting There is no longer any performance improvement The engine begins to cut out at high speed Danger There is a sudden loss of power during acceleration Danger The engine begins to overheat Symptoms of overheating include Steam or smoke coming f

15. E TRX 3 3 RACING ENGINE People have differing opinions on what is the proper procedure to break in a model engine Only use the Traxxas break in procedure Other break in procedures could result in a weak damaged or otherwise poor performing engine The procedure outlined here was extensively tested and proven to yield better performing engines than other common break in methods Even if you have years of experience using model engines please do not ignore this caution Engine Break in Procedure The focus during break in is to vary and limit the engine speed This will be accomplished by accelerating and stopping at different rates for the first 5 tanks of fuel As the engine begins to break in the duration and intensity of the acceleration will gradually increase Sustained high speed running is not permitted until the 6th tank of fuel Perform the initial break in on a large flat paved surface Revo is very fast and by tanks 4 and 5 you will need plenty of room for the truck to run in Apply all throttle and braking actions gently Abrupt acceleration or braking could cause the engine to stall unnecessarily e Special break in fuels are not recommended Use the same fuel you plan to use everyday If possible avoid breaking in the engine on extremely hot or cold days see page 9 Pay careful attention to the fuel level Do not allow the fuel tank to run completely empty An extremely low fuel level causes the mixt
