BATTERY RECOMMENDATIONS FOR E-MAXX

It is important to know what battery packs should I buy and how to charge them? There are so many battery packs available that it is hard to make specific brand recommendations. However, here are a few points to keep in mind about batteries and charging.

If any battery pack gives higher the mAh rating, the longer the battery run time. That is, a 3000 mAh battery pack will provide with twice the run time of a 1500 mAh battery pack. Battery packs with 2400, 3000 or 3300 mAh ratings are expensive to purchase. If cost is an issue, 1500 to 1800 mAh NiCD packs are very economical to purchase and work well in the E-Maxx The battery packs should be 7.2 volts and have a standard Tamiya connector as well and should be assembled with 6 sub-C sized cells.

The 6-cell NiCad or NiMH battery packs should be charged between 3 and 5 amps on a peak detection charger designed for both the packs. For backyard bashing or general use, a 3 to 4 amp charge rate is recommended. For racing, a 5 amp charge rate is recommended, but lower charge rates are fine too. If recharging the battery packs is required then they should be allowed to cool down completely before any re-charging is done else the packs would be damaged.

While storing, NiCad battery packs should be completely discharged before they are recharged or stored to maintain optimum performance. On the other hand, NiMH battery packs need not be to be completely discharged before they are recharged, but it is recommended that NiMH packs be fully discharged every 4 to 8 weeks. If NiMH packs are not going to be used for more than two weeks they should be partially charged 30 to 50% of their maximum capacity. For long-term storage of NiMH packs it is suggested that they should be fully charged. The easiest way to discharge your battery packs is to simply run them in your E-Maxx until the truck slows to a crawl.

It is important to know how many battery packs should one buy? Six battery packs is an excellent setup because then one can have two packs running E-Maxx, two packs charging and two packs cooling, which means that obtaining uninterrupted run time. It is important to remember to let battery packs cool down before charging them again or else it significantly decreases their life expectancy.
Moreover it is more economical to have two battery chargers. It is also the only way to have a whole day of uninterrupted run time or fun. Alternatively, a peak charger can also be purchased that charges two battery packs at the same, such as the excellent MRC Super Brain 969 Pro Charger.
Usually E-Maxx racers typically like to charge at 5 amps because their battery packs have a bit more low-end punch or torque. If one is serious about E-Maxx racing, it is preferable to purchase a charger(s) that allows charging up to 5 amps, such as the Integy 16X3-Pro v2.5 VESC or Novak Millennium. However, for backyard bashing or sport use, charging packs at lower amps (3 to 4) provides good performance and extends battery run time in comparison to charging at higher amps. Also, battery packs that are charged at lower amps have an increased life expectancy in comparison to packs charged at higher amps.
It is not difficult to choose between the type of the battery pack to be purchased. NiCad or NiMH battery packs both work fine in the E-Maxx However, people that have a low budget NiCD charger with a timer should stick with NiCD packs because these timed chargers were not designed to properly charge NiMH packs.
Further, NiMH packs can be destroyed by excessive heat. So one needs to be careful not to overcharge NiMH battery packs! NiMH packs are fully charged when they feel slightly warm. For charging NiMH packs, a peak detection charger designed for NiMH batteries is recommended.

BATTERIES FOR RC CARS

If you had been using been running cheap nimh 6cells 3000mah and also a 7cell nicd 1500mah battery packs and you though these packs thought were pretty good, here are some wise words that you had been living in an ignorant bliss.

Trying GP1100 7 cell would make you notice the difference in torque. The wheels would spin on take off and keep spinning and if you put 6 cell GP2000 you would notice that it is faster than 6 cell 3000Mah

Batteries make all the difference, especially matched packs. Elmo makes GP's available to the common RC cars for very low prices. They're not matched packs, and they're not priced like matched packs either. Maxamps are also fine but their packs cost like 6 bucks more than Elmo's. Maxamps advertises "factory matched" meaning they are within .02v of each other, which is the difference between a 1.16 and 1.18 cell. So basically they are the same cells as Boom Boom Batteries.

Boom Boom Batteries are coming out with matched packs. They got the machine setup already and have to just make some packs. IB3600s have known to have problems with voltages, lifespans, and run times. The IB3800s are apparently way superior to even the GP 3700s. They have very high voltages and long run times.

For some time now SPC has been selling 6-cell, matched, loose GP3300s. If you are looking for 2 assembled packs check out their Twin Maxx Pacs. For a reasonable price you get two, 6-cell matched and assembled packs of GP3300s. Runtimes average around 425 seconds at a 30-amp discharge. They are great packs with good soldering quality.

7.4v 830mAh Lithium Polymer (Poly-Li) Battery Pack have super high rate - 10-12C and also superior power and strength that makes you RC car or airplane a true champion. It uses a voltage of 7.4v and has capacity of 830mAh. It weighs only 1.5 oz. i.e. significantly lighter than NiMh battery pack. Lighter battery packs makes your engine runs much faster.

4.8V 1600mAh NiMH Battery Packs for RC Toy Cars have a voltage of .8V, 1600 mAh NMH? It also has a receiver battery for RC car. One gets to enjoy highest capacity and running times. It is compatible with all Nikko and RadioShack RC Toy cars.

7.2V 3000mAh Sadle Battery Pack for RC Car High quality is 7.2 V, 3000 mAh, saddle shape battery pack made of matched NiMH cells (6xSc). It rapidly charges up and high drain current up to 30 Amp. It fits many Losi and HPI RC vehicles. The best buy would be to buy two battery pack Plus a smart charger to keep your car running. Some precautions need to be taken with its charger, like not to use the charger for low capacity batteries pack (1100mah) or charge any other battery using this charger. Similarly, this battery’s charger is not to be used to charge 6V battery pack over capacity 3000mA or 1500mAh at 1.8A current level.

AIR FILTER MAINTENANCE FOR TRAXXAS

Traxxas is the market leader in ready-to-run (RTR) nitro and electric radio controlled models. Traxxas continues to advance the RTR category with innovative thinking and fun designs that make it easy for anyone to get started in the world of R/C models. From the phenomenally successful T-Maxx and E-Maxx monster trucks to on road and off road vehicles, Traxxas defines ready-to-run. Batteries, chargers and fuel (for nitro vehicles only) are not included with Traxxas models and must be purchased separately

Air filter for the traxxas needs to be cleaned very importantly for regular flow of the fuel. In order to achieve proper cleaning of the same a complete guidance is necessary. It is also important to always run the engine with the air cleaner installed!

The air filter prevents harmful dirt and foreign objects from getting into your engine and destroying it. A nitro engine is precision made and you don't want dirt and grit to get in their while it's running at 40,000 RPM! At those astronomical engine speeds, dirt will quickly ruins lovely expensive engine. Periodically, as the foam filter gets plugged with dirt (reducing power), one should remove it from the engine and clean it with household dish washing liquid, Simple Green degreaser, or some other degreaser. Gasoline or other strong solvents should be necessarily avoided as these could damage the filter. In a pinch, one can also rinse the filter clean with Rubbing Alcohol or even nitro fuel. It needs to be made sure that the filter element is dry before re-oiling the filter. Moreover a small cable should be used to tie to secure the filter to the carburetor to prevent the air filter falling off!

First the air filter from the carburetor needs to be removed. Then throttle is required to be opened fully and squirt a one second burst of WD-40' into the carburetor. This also need to be done for the glow plug hole inside of the cooling head.

Placing a towel over the glow plug area of the cooling head would enable to catch any WD-40' that may come out of the engine. Next the engine is to be cranked over with the EZ-Start system for about 10 seconds. If the model uses a pull starter, several series of short pulls should be made in order to circulate the WD-40'. This procedure needs to be performed several times.

Then the air filter element from the filter housing should be removed. Clean the element and housing components with warm soapy water or dish washing liquid and allow the pieces to dry completely.

The air filter base needs to be squeezed just below the housing and then the base out should be pulled out from one side for easy removal.

The element should be cleaned with fingers until completely shining. Compressed air can be used to accelerate the drying process of the air filter components. Once the filter element is dry, apply 30 drops of Traxxas air filter oil should be applied, part #5263, evenly around the entire element.

Thirty drops of Traxxas air filter oil is suffice. Oil from the element should not be squeezed out. Instead it should be spread evenly on to the element with fingers until there is an even color of oil throughout the entire element. Then the filter element should be reinstalled into the filter housing.

Traxxas recommends to clean the air filter after every hour of runtime with the engine (approx. one 500cc bottle of fuel). If the vehicle is operating in very dusty conditions, cleaning the air filter after every 30 minutes of runtime will be necessary to promote long engine life.

ADVANTAGES & DIISADVANTAGES OF THE E-MAXX

This is the most exciting electric R/C truck to be released in years. The E-Maxx is the best performing electric monster truck on the market today and light years ahead of the competition. The E-Maxx is perfect for both back yard bashing and racing.

E-Maxx has been so far the best handling large-sized electric monster truck ever produced by Traxxas. It has more torque and top speed than any electric monster truck ever produced. Its the suspension delivers 4 inches of maximum ground clearance and over 3.5 inches of super plush suspension travel with eight oil-filled shocks.

It has twin fan-cooled 550 motors have 30% longer armatures and more torque than standard 540 size motors. Its 4-wheel drive makes the truck capable of going over any terrain and improves handling on the race track, especially around curves. It includes an electronic speed control (ESC), not a mechanical speed control or MSC. An ESC provides a lot better performance than a MSC in terms of throttle response and battery run time, which is why you want one. The stock ESC, which is called the EVX, is made by Novak and has many features, including forward, reverse and brake functions. The overall design is very tough and can take a lot of abuse.

Features of an E-maxx are very tough, molded composite chassis with battery cutouts that lower the center of gravity when using side-by-side racing-style battery packs. The battery holders accept both stick packs and side-by-side race packs. It comes with a custom painted body with precut decal set. It has body mounting posts, which allows for a large variety of body choices.

It also has a two speed, manual shifting transmission. Low gear provides brutal acceleration and tons of torque for climbing and doing wheelies. High gear provides an insane top speed of around 30 mph with 7-cell battery packs or 23 mph with 6-cell packs. Its pinion and spur gear changes are very easy to do. Morever, a huge variety of gear options can be installed. Its stock motors have internal fans and run very cool. Cooler running motors last longer than hot running motors.

E-maxx comes with ball-bearings, which improves performance in terms of top-end speed and battery run times. It also comes with a slipper clutch, which reduces transmission damage. This is especially true when jumping the truck. A very important feature of E-maxx is that it comes as Ready-To-Run or RTR, which means that one does not have to build it or install a radio system. Its battery packs are also easy to install and remove.

A huge assortment of aftermarket parts is available for improving both the looks and performance of the E-Maxx. It is good for both backyards bashing and racing. It give an outstanding performance at jumping because of awesome suspension system. The battery run times are outstanding considering the size and weight of the E-Maxx. Morever its parts are easy to obtain and can also be ordered online via various hobby e-shops.

As regards to the company, Traxxas provides outstanding customer support - probably the best in the R/C industry. It has also changed the way people view the monster truck category. The added advantage of this is that the E-Maxx comes within a very reasonable price category.

Although E-maxx has so many advantages. Nevertheless, it has its own drawbacks as well. Its stock steering servo is somewhat weak; that is, the steering servo will not turn the E-Maxx tires while the truck is stopped. It is also somewhat vulnerable to damage. A steering servo cover is recommended for deep grass or brush running. Although the truck is marketed as ready-to-run, but the tires need to be glued. It is also not offered as a kit and some people like to build their own vehicles. if someone is into exact scale realism the E-Maxx is not for sucha person. E-maxxx requires dual battery packs for operation, which means one has to buy a lot of batteries.
