and a kit comes with just a rolling chasis? no electronics, radio, batts, motor, etc
i really like that Associated rc12l4 but is it oval only?
There are basically three types of 1/12th scale kits. T bar cars, link cars and U block cars. The T bar cars are probably the most common and consist of the Associated 12L3, 12L4, the Trinity Reflex 12, the Yokomo YRX and the Corally cars from Europe. The Associate cars are the easiest to get parts for as most hobby shops carry them. The Trinity car, while very unique and with interesting design features, can prove to be problematic in acquiring parts.
Then come the link cars. These types of cars have a pivot ball connecting the motor pod to the main chassis and two parallel links on either side of the battery pack that keeps the motor pod square to the chassis. These types of cars are the Calandra Carpet Knife (CRC) and the Speed Merchant Rev 3 and Rev 4.
Lastly is the “U” block cars or at least that’s what I call them. They are a derivative of the pivot ball cars but do not use two parallel links. Instead they have a large aluminum block in an upside down U shape that goes through two large diameter coil springs to control the fore/aft and side to side movement. These cars where made by HPI exclusively and are very hard to find as they are not made by HPI any longer. The Hara Hammer 12 is a design by Atsushi Hara that uses an Associated dynamic strut front end with the HPI rear design. These conversion kits are available on a limited basis from Stormer Hobby and some other internet dealers. Hot Bodies is the sole importer.
Now there are a bunch of derivatives of the T bar cars and range from conversion kits to full kits. There is the Josh Cyrl CFX but with his own front suspension design. The Quad 12 from Doug Powell, the IRS Rug Rat and the CRC T Force as well as some others that I may have failed to mention. Most of them use either the Associated Dynamic Strut or the Associated early design front suspension except for the CFX as mentioned. All of them are of very high quality and improve on an already very good design.
The first thing in picking a 1/12th car is first decide what type of racing you are going to do. The general consensus among racers is that for carpet a link car works best for stock racing while a T bar car works best for modified, although I have run both types of cars in both classes. Outdoors on asphalt the T bar cars reigns supreme but again, I have seen link cars run with some success. All of the cars use a center shock/spring system to control fore and aft movement and either dampener plates (Associated) or dampener tubes (CRC, Speed Merchant) to control side to side movement.
There is a lot of part interchangeability between the cars as well as a bunch of aftermarket parts made by independent companies. Which ever car you choose I am sure you will find 1/12th scale cars to be the most fun you will have in RC car racing.
