GETTING TO KNOW E-MAXX RC CAR

The E-Maxx is a radio controlled ( R/C ), 1/10 scale, electric powered, 4-wheel drive, monster truck produced by Traxxas Corporation. When it comes to gut-wrenching, wheelie-popping monster torque, nothing comes close to E-Maxx! Twin Titan 550 motors, trick 14.4V ESC power, 3-channel radio system, ball bearings, 8 oil-filled shocks, painted body and shift on the fly 2-speed transmission all put the E-Maxx in a class by itself. E-maxx is the best, most innovative, hobby quality monster truck. It comes as completely assembled and the body is painted and trimmed.

While running the E-Maxx for the first time it important to totally check over the truck for loose screws, nuts, wire connections and bolts. It is also a good idea to check the model over after a few runs to make sure nothing has come loose from driving. It should be made sure that the pinion grub screws are tight and that the pinions do not slide on the motor armatures. The slipper clutch nut should be tightened fully. It is located on top of the spur gear spring, which is located between the pinion gears. The bullet motor connections should be tightly pushed together. The servo and ESC wires should also be fully pushed into the receiver the truck may function erratically. Another reason to make the truck function erratically is if the crystal and radio crystal are not fully pushed into their slots. Also, If sand gets inside ESC this can also make E-Maxx function erratically.

Usually there are no problems with E-maxx but some trucks have known to be shipped with loose pinion screws, slipper clutches and motor wire connections. It is advisable to check ones E-Maxx over to ensure that the latter problems do not exist. Also, some of the first trucks produced had unreliable electronic speed controls, which Traxxas replaced with the EVX. The EVX is an excellent speed control.

A spool is technically called a differential spool. According to Traxxas, the differential spool replaces the rear differential gears to make the truck unstoppable in hard-core climbing maneuvers. The spool locks the rear axle, which in turn provides equal power to both the rear wheels no matter what the truck drives over. Because the spool locks the differential, it should be used strictly for off-road. If someone is building a radical, special purpose E-Maxx for straight-line sand drags, hill climbing or pulling, then a spool needs to be installed in the front as well for total 4WD traction.

Sometimes the noise from some models of E-Maxx transmission seems loud. It can leave one wondering as to why does it happen and what can be done to make it quieter? The reason behind the same is that the 32-pitch gear transmission of the E-Maxx is rather noisy by design and this is nothing to worry about. Nonetheless, if one wishes to reduce the gear noise, a bit of additional transmission grease can be put on the gears or change to 48-pitch gears (pinions/spur). Also, a check should be given to the pinion/spur gear mesh - too loose will create excessive gear noise. A bit of silicone grease that is designed for transmissions isn't going to hurt the gears, whether plastic or metal.
