Default Sprint car??

Been looking around and was surprised information was scarce. I'm wanting to get back into this hobby after a long time away and one of my local tracks does dirt oval running "modified" looking type cars and "sprint car" looking cars that appear to be based on buggy chassis. I used to race dirt offroad buggy and loved it but know nothing about sprint car buggy. Any good resources out there? Also namely on currently electronics, my stuff is 20 years old and I plan to replace everything. Any help is appreciated!!

Check with the people racing them at the local track or the hobby shop.

dirt oval has changed a bit in the cars. Most of the growth is in the traxxas based mudboss class or buggy based conversions (Sprint cards and midwest modifieds)

Buy new electronics and be done with it.

Check out some of the RC dirt oval pages on FB for more information.

See what is being run at your track. Custom Works makes a loose dirt sprint car. Not buggy based, but uses hexes and is meant for loose dirt. Velocity and several others have conversions for buggies or trucks into sprint cars and midwest modified.

Good info already, just to add a bit ... 1/10 sprint cars will be 'buggy based' (meaning by wheelbase) cars, where (primarily) either an Associated, Losi, or Xray 2wd buggy kit is used along with a 'conversion kit' which supplies needed components to complete as a dirt oval sprint car, midwest mod (MWM), late model, etc ... a few examples of 'conversion kits' offered would be from Five Star, which sells AFX, Tech-Lite, Velocity, RIP, F5 Chassis, Triple P, etc ... Bodies by Ed (BBE) was a major player for years before purchase by Five Star ...

Another option, is a company like Custom Works, which fabricates and offers complete kits for use in dirt oval applications. with no 'donor car' (from other mfr) needed to complete, which are referred to as 'purpose built' cars ...

Another consideration, is surface which the car will be raced on ... 'high bite' will refer to an extremely well groomed (usually) clay surface, where it will very possibly be foam tires used in that application, and usually with a 'high bite' car which is built to take advantage of these conditions ... the other would be 'loose dirt' cars, which could be raced on anything from an indoor 'groomed' track, to an outdoor sand/gravel/mix surface, and everything in between, and utilizing rubber tires with a variety of tread/compound types ...Custom Works for example, will offer kits specifically designed for high bite, and loose dirt oval applications ...

Other common R/C dirt oval cars you will see, are short course (SC) truck based (again by wheelbase), and in this category you will find dirt oval conversion from offroad short course truck kits by the mfr's mention above, among others ... you will usually find a variety of 'modified', 'late model' and 'stock car' classes utilizing SC based chassis vehicles ... they will be dictated by local/national track rules as to the extent of the modifications allowed to be made, from nearly 'box stock', to 'open' with very few limitations ... the Traxxas Slash (SC truck) has become a major contributor to the number of cars and classes that are being run, some areas of the country more than others, and in a few different varieties, as stock cars, modifieds and late models ... you can't do much in the dirt oval world these days without hearing about the Slash based MudBoss, which is an RC version of the East Coast MudBuss full size cars ... the midwest has been using the Slash platform more for a 'Slash Mod' type car, which although very similar to the MudBoss, uses a different body style (similar to the modified cars used on Midwest full-size tracks), but the MudBoss style cars have slowly been making their way across the country now, as the class has one of the most widely accepted rules package wherever you travel to ...

As Silverbullet mentions, FB is loaded with RC Dirt Oval pages, YouTube shows quite a bit as well ... the best advice is already given, visit local tracks which you will likely be racing, as rules and classes offered can vary, even from year to year ... also, some of the best used car buys often come from the local track you will be racing, the car is likely set up for that track and rules...

Regarding electronics, technology has indeed advanced significantly in the last 20 years. For current electronics suitable for dirt oval racing, forums like R/C Tech can be a great place to ask for recommendations and read about other racers’ experiences with different brands and setups. Additionally, websites like Rugged Radios offer a variety of communication kits and electronics tailored for racing.
