Our base class, the TT01's usually be the start of u're racing hobby.
This info taken from the web:


TT01 vs. TT01 E By Andrew Kuntze


Intro:
The TT01 has long been known as a great kit for beginner and expert drivers alike. The kit features a rugged 4wd platform to help novice drivers learn the basics of radio control at a low cost, while allowing more advanced users to choose from a wide variety of hop up options to use on the track. In 2008, the Tamiya engineers took this great platform and added new parts to create the "Enhanced" version of the TT-01, dubbed the TT-01 Type E, or TT-01E. This next generation TT-01E features many improvements over its predecessor, while retaining the key features that make the TT-01 platform so popular.

Enhancements:
Newly designed front uprights (A parts) have been added to improve the handling of the chassis. These new uprights are made from a polycarbonate plastic material, which reduces play, in turn, making steering and handling sharper and more precise.
A new upper deck has also been added to increase the overall rigidity of the chassis; this solid foundation yields to better handling and provides a more responsive racing chassis. The upper deck also incorporates a new transponder mount for those that wish to race their car.


The redesigned upper deck features a motor guard to prevent new hobbyist from touching a hot motor and possibly burning a finger.



The steering system has been completely redesigned to feature the race proven TA05 steering system. This racing inspired steering system helps to provide less play and more precise steering response.


New front and rear shock towers are now molded separately from the gear case covers. This improvement makes maintenance much simpler. Now mechanics will have direct access to the front and rear gear boxes without removing the shocks.




New Hop Ups:
Along with the new standard features above, the TT-01E has inspired the engineers at Tamiya to develop more hop-ups for racing. Combining these new hop-ups along with existing TT-01 hop-ups can provide racers with an even better chance of finishing in the winners circle.


Ball Bearing Set - 54025


With the new designs incorporated into the chassis, a new bearing set was created to replace the stock plastic bushings supplied in the kit. The ball bearings are one of the easiest upgrades to free up the drive-train of the TT-01E and make the car more efficient for less power loss.



Aluminum Propeller Shaft and Joint Set - 54026


The newly designed aluminum propeller shaft also comes with an aluminum front and rear joint set to replace all of the stock plastic parts in the center driveline. These parts will further improve the efficiency of the drive-train to reduce power loss. Keeping the drive-train as efficient as possible is the key to getting the most out of your motor.



Aluminum Steering Set - 54058


If the newly designed steering wasn't an improvement enough, you can take it to the next level with this aluminum steering set. This set will make the steering of the TT-01E more precise than the stock plastic pieces. Upgrading the steering will also put less strain on the servo and increase its life.



Front Carbon Damper Stay - 54059


With the implementation of the new two piece gear case covers, you are now able to upgrade the damper mounts to these new 3mm carbon pieces. Like the TRF cars it is inspired by, this new damper stay offers another adjustment for the suspension. In addition, when paired with dampers from the M Chassis Aluminum Damper Set (54000), you can use the new generation of low nose bodies as seen on the TA05 IFS and TB03 chassis.



Rear Carbon Damper Stay - 54060


Like the front damper stay, the rear piece is made from the same 3mm carbon that offers you the ability to change the angle of the dampers and have greater adjustability when you go racing. Unlike the front, the rear damper stay can be used with any Tamiya touring car damper set.

Conclusion:
With the enhancements made to the new TT-01E, and the new variety of hop up options that you have to choose from, the TT-01E will continue to be very popular among beginner and expert drivers alike.

For the guys doing "NATS",look at this Travel bag:

The SC RaceCase II Limited AE Edition with blue trim is a great way to transport your SC10 or SC8 to the track! It’s also a great way to carry all your Team Associated cars and trucks, as more than just a 1/10th short course will fit. With the optional mid-deck installed, the RaceCase can carry two on road sedans up to 200mm! Once the mid-deck is removed the RaceCase can transport an 1/8th scale buggy with the tires and wing on, comp and scale crawlers, 1/10th scale off road trucks and buggies, and of course 1/8th and 1/10th scale Short Course trucks!
An integrated radio compartment offers easy transmitter storage, or extra room for tires and parts. There are also two external pockets with tough zippers for extra storage. The Removable tool tray can stow seven drivers snug inside elastic loops, and can easily Velcro in and out of the bag to go to your bench or pit space at the track. Reinforced carry handles in two locations offer comfortable carrying positions no matter what you’re transporting! The shoulder strap also offers a hands free carrying position for the ultimate in comfort and convenience. All these features make The RaceCase II the Ultimate Transport Bag!
This bag ships flat, but once the internal radio compartment divider is installed it really takes and holds it shape. The walls have plastic inserts built in, for added strength and rigidity.

The Serpent S400 :
Introduction
Serpent enters the competitive electric touring car market with the S400, which like all our previous cars, has been designed to win straight out of the box. Featuring an ultra low centre of gravity, optimized weight distribution, high performance geometry and top quality materials throughout, the S400 should see you in the winner’s circle in no time. In fact everything associated with this car is of the highest quality, from the packaging and supplied manuals, right through to the product and race support.




Rear end
The rear end of the Serpent S400 has been designed for high performance and ease of maintenance. The rear bearing blocks have been designed in 2 pieces which allows the topside to be simply removed with 4 screws, giving you easy access to the differential for maintenance or adjustment. All the parts have been machined from aluminium and have anodized in gun metal grey.




Rear suspension
The rear end of the S400 features strong 1-piece lower wishbones and aluminium uprights. As with all the wishbones on the car, the lower wishbones can be used on both the left and right sides, minimizing the number of spare parts needed to bring to the track. The rear upright features a pivot pin mounting point on the bottom and three upper camber link mounting holes for fine-tuning camber rise.




Rear Differential
The kit version of the S400 comes supplied with a lightweight and smooth rear ball differential. The diff halves are made from hard anodised aluminium which is lightweight yet extremely strong, while the use of high quality balls and steel plates ensure a long lasting and smooth diff action.




Drive train
The S400 drive train utilizes a 2-belt system with rear ball differential and front spool, while 4 CVD (constant velocity drives) transfer the power to the wheels. The motor, which is mounted to an aluminium plate, powers the main spur gear and hard anodised aluminium pulleys.




Front suspension
Similar to the rear suspension in configuration, the front suspension sports a lower composite wishbone while the upper camber adjustment is handled using a track rod which is solid, lightweight and can easily handle impacts.




Front C-hub system
A standard system on all high-end touring cars, the S400 features a front C-hub system, which is a lighter alternative to a pivot ball steering system. The car comes standard with a 4-degree caster block but is also supplied with a pair of 2 and 6-degree blocks.




Servo Saver
The servo saver on the S400 features 4 steering rod mounting points to allow the user to easily adjust the cars Ackerman. The servo saver system itself features a nut for adjusting the spring tension of the saver.




Chassis
The chassis plate has been machined from a plate of 2.5mm thick carbon fibre, which creates a perfect platform for the cars electronics as well as stiff structure, especially when combined with the equally rigid 2.5mm thick carbon fibre top deck. All holes in the base of the chassis have been countersunk while on the top of the plate, the area around the motor has been milled down to allow it to sit as low as possible. The plate features cooling holes below the motor and speed controller.




Anti-roll bars
The S400 is supplied with colour coded anti-roll bars front and rear that are held in place using a 2 piece anti-roll bar mount. The anti-roll bars are available in a number of thicknesses and are connected to the wishbones using short adjustable track rods. Stiffness is quickly and easily adjustable by changing the linkage mounting points on the lower wishbones or alternatively by changing the position of the ball joint pivot point on the roll bar itself.




RCC Shock absorbers
The RCC shock absorbers are the smoothest and easiest to build shocks ever designed. Machined from aluminium and unique in that the shock bodies only open on the bottom half, they are really simple to assemble. The result is an ultra-smooth and air-free shock absorber thanks to the self-bleeding system incorporated into the design. The shocks are supplied with 4 different shock pistons.

Another great benefit is that these shock absorbers come pre-assembled in the kit, so you need only add shock oil.




Front axle
The car comes supplied with a front spool which has been made from hard anodised aluminium while its shape has been optimised to ensure that the part is as light as possible without compromising strength. The drive is provided through the attached pulley into the lightened steel drive cups, which are held in place using steel pins.




Shock towers
The Serpent S400 features 2.5mm thick carbon fibre shock towers on the front and rear of the car. Each tower sports numerous holes for adjustment of the shock absorber angle while the rear tower also acts as the mount for the rear body posts and the front tower accommodates a 3rd front body post.




CVDs
This car is supplied with a complete set of 4 high quality hard coated steel CVD shafts, which are a highly consistent, efficient and durable way to transfer all the power the ground.




Suspension brackets
For adjusting the cars toe-in and track-width, the S400 is equipped with separately mounted suspension brackets on both the front and rear of the car. Each bracket features an easily recognisable number that corresponds to the setting being used and due to the way they are mounted allows the user to easily and accurately adjust their cars settings.




Steering system
The Serpent S400 utilises a centrally mounted steering assembly that contains the servo saver and Ackermann adjustments. Controlled by a side-mounted laydown servo, the steering assembly is ball raced precision and due to its central position it is much lighter than more complex off set steering systems. The tension of the servo saver spring can be adjusted using the supplied adjustment nut.




Bumper
The front bumper has been made from a high impact absorbing foam material and is shaped to protect the entire front end of the car in the event of a crash. The bumper is held in place with a large stylish carbon plate that features the S400 logo cut out of it.




Belt tensioner
Secured to the cars top plate, this machined aluminium piece acts as the mount for the aerial as well as the cars ball raced belt tensioner.




Bearings
The S400 is supplied with high-quality lightweight bearings throughout, making the drive train very efficient and allowing it to run very smoothly.




Belts
The S400 features a 2-belt configuration with a long front and a short rear Kevlar reinforced belt that makes for a super smooth and free drive train.

A little bit about batteries:

The NiCd Battery was invented by Waldemar Jungner of Sweden back in 1899, also pronounced "nye-cad", there are two types of NiCd batteries: sealed and vented. The main advantage that NiCd batteries have over other types is that you get more charge for the weight, which in the RC hobby is a critical element, where every gram saved makes a difference.

NiMH Batteries are the most common in hobbies and radio controlled cars. These use a hydrogen-absorbing alloy rather than cadmium as in the NiCd Batteries. NiMH doesn't hold as much charge-per-weight as the NiCd, and if left for a while they self-discharge. More care is also needed when storing these batteries, the generally accepted method is to leave them with 50% change when storing them. Then when you want to use them you need to discharge and peak the battery.

While most batteries don't have a a memory, it's always best to look after them as this will increase their life span. It's always a great idea to attach Ultra-Plugs a.k.a Deans plugs when you first get your battery.

The main advantages of NiMH batteries over other types are :

■NiMH batteries are ideal for high current drain applications, like racing radio controlled cars
■NiMH batteries are relatively inexpensive and can be found from almost any electronic or hobby shop
■While the voltage is slightly lower, they are the idea replacement for alkaline batteries
■The newest NiMH batteries have a low self-discharge rate, much lower than pre-2005, this has increased their shelf life considerably
NiMH are the batteries most commonly used in hybrid and electric full scale cars

The LiPo batteries evolved from lithium-ion batteries. We don't really see these anymore, at least not in hobby shops and radio controlled vehicles, NiCd and NiMH are far more popular, cheaper and more suited to sudden and long discharges.
When it comes to LiPo and hobbies there are not really any advantages

■All battery type require a specific type of charger, only the most expensive ones support all three type
■The other battery types will give less problems, last longer and deliver better power
■The discharge can be a little erratic with LiPo
