Tires are a key point to making your vehicle run and you want to make sure that the tires are set up in the most effective way possible. First you have to rub some rubbing alcohol on your rims and mounting channels. Then wipe off the rubbing alcohol and whatever it picked up with a paper towel until nothing shows up on the towel anymore. If you want an even tighter bond between the tire and the rim, you may want to lightly sand the rim before rubbing it with alcohol. Secondly, center the foam insert in the tire and don't do any trimming unless the entire insert does not fit in the tire. Put the tire with the insert on the rim and make sure that there aren't any lumps. Then, put a rubber band around the tire and rim so that they are held tightly together. Third, you need to start glueing. You have to pull the tire sidewall just far enough away from the rim so that the glue can get down to the bottom of the tire-mounting channel. Put four, evenly spread out, small drops of glue on each side of the tire. Make sure let one side dry before flipping over the tire and starting on the other side. Lastly, you need to give a gentle pull on the sidewall and put a drop of glue where the loose spots are if there are any. Seal the edge of the tire, or bead to the wheel by putting a full drop of superglue between the tire and rim. Tilt the tire a little and then slowly rotate it 360 degrees in your hand so that the glue spreads all in between the bead and the rim. Let this dry before starting the other side and remember to not run your newly glued tires. Have fun.

About Batteries
When deciding how to power your electric vehicle, you need to know all the information that you can about what batteries will fit your needs the most. The most popular type of battery to use for electric radio control is the Nickel-cadmium battery, or NiCd. These batteries are pretty lightweight, have a great charging efficiency and are harder to damage than most other batteries. They are also compatible with most, if not every speed control. Next, there is the Nickel-metal hydride battery, or NiMH. This type of battery is very closely related to NiCd batteries and also fits most speed controls like the NiCd as well. However, a NiMH battery can weigh 2-3 times more than a NiCd battery of the same size, and its memory effect is not as efficient. Lastly, there is the Lithium-ion polymer battery, or LiPo. This battery is a technologically evolved version of the Lithium-ion battery. Very few speed controls will accept this type of battery because of its high energy output. But this battery can be up to 30% lighter weight than a NiCd or NiMH battery and can also put out up to 30% more energy. On top of all of that, this battery's life can last so much longer than any other battery allowing you to run your vehicle at its best again and again for as long as you want.

Choosing Parts
When choosing parts to go inside your vehicle, you must make sure that everything is compatible. I recommend parts that don't require sottering because that is just a hassle. Also, you do not want to get a Brushed Motor because it overheats and could cause a flame-up depending on what battery you use and how long you run your vehicle for. If you want to race your car, buggy, etc. you probably do not want a speed control that goes backwards, however if you are just going to be having fun with it, you may want a reversable speed control. When you decide on a speed control that fits your needs, make sure you know what kind of batteries it will operate on and what the minimal turn limit for the motor is if there is one. Once you have that done, you need a motor that has a turn above the limit on the speed control. The higher the turn, the more power it takes to run the motor causing your vehicle to go slightly slower. On the other hand, the lower the turn, the less power it takes to run the motor, making your vehicle go faster. Not many speed controls accept li-po batteries, but if they do, you may want to think about purchasing a li-po battery. They are 30% less weight than a nimh or nicd battery and have a 30% longer run times. You may also want to look into a cooling fan or other unit to cool down your vehicle. This insures that there will be no overheating and allows you to run your vehicle for a longer period of time. The last interior component that you need for your amazing racer is a steering servo. This controls the steering and when picking one out, you may want to purchase one that is manufactured by the same people who make your transmitter or pick one that is compatible with your transmitter. To run your vehicle, you need a transmitter and a reciever. I recommend a 2.4GHz, 2-3 channel transmitter and a reciever that is made by the same manufacturer as your transmitter and is also compatible with your servo, speed control and battery voltage. Lastly, to make sure that you do not have any glitches between your reciever and your transmitter, you may want to purchase a transmitter capacitor which will prevent any problems from occuring or fix a problem that has already happened between your reciever and transmitter.

The Team Associated B44 Kit
At a whopping price of $324.99, the B44 is not the cheapest thing around. It doesn't come with a motor, servo, speed control or even a battery, so why buy this over, lets say a Traxxas? Well, Team Associated gives you the quality merchandise to race or to just have fun wherever you are and under whatever conditions, and with how durable their supplies are, you won't be needing to replace anything serious for awhile besides maybe some tires. In the long run, this will save you loads of money! Also, since it does not come with any key components, it gives you the opportunity to put what you want in it rather than buying a ready to run buggy that has low quality parts anyways. So if the kit does not include a motor, servo, speed control, battery, or transmitter, what does it include? It comes with a composite front bulkhead and rear chassis plate to add more space between it and the ground and also improve its durability. Also, the buggy is built with blue titanium turnbuckles, blue aluminum shock bushings and blue aluminum servo mounts which improve durability as well and makes this buggy a wonder to drive. A shaft drive powers the buggy making it's speed unbelievable and it's acceleration quite quick. Each wheel has its own aluminum shock tower and gold shock shaft which make any bump or hill a breeze. Lastly, it has 4WD which gives this buggy an advantage in any climate, on or offroad, over any other buggy on the market.
