If you are interested in joining or checking out a show the are 2 tracks in Texas one is RCQMA located in Austin, its one of the bigger tracks around it has soft walls electronic scoring and scorebored and tower. Its off of I 35 between Braker and Yager Lane. I am a member there. Great club and great people. They are working to host the Grand Nationals in 2010. As far as cost these are not home made cars anymore. Brand new without an engine is about 5,000 there are tons of really good used cars with motors anywhere from 1000 on up. Keep in mind, they are race cars and with any car the equipment and the driver is the differnece. Now as far as engines go, the older Decos are now the super stocks and Modifieds B's and AA these motors range from 2000 dollars on up. They require a ton of maintenance and pretty much everything is custom made. My modified that I had cost 3100 to build. it was fast but expensive. The engine of choice is the Honda 120 new these motors are about 700. Very little can be done to these motors per the rule book and the car counts are huge. They are very similar to each other so the difference is the Driver , car and set up. tires play a huge role in performance. We were able to turn the track in Austin at around a 6.6 second lap time while in San Antonio the lap time are at around 5.8. that is really quick especially when you add 10 cars in traffic. Very exciting stuff. You can start out at age 5 and run till your 16 if you like. The track in San Antonio is located at the Comanche Park off of Rigsby avenue. If you go to our web site there is a Quarter Midget tab and all of the links for information is right there. Hope this helps
