Can't speak for the whole country, but in the TCS, and UF1 series it is all narrow/tall rubber tires that emulate the modern F1Grand Prix cars, Most popualr brand is Shimizu, TQRC is the USA importer, and recently Tamiya USA have a Tamiya TCS branded vers of the Shimzu tires
2. What bodies and wings are you using and where do you get them?
Tamiya Bodies and wings are the most popular, 3Racing have a bodyset for their FGX also, bodysets are available at TQRC, Speedtech, and many dealer, distributors wordwide
3. How adjustable are the front ends of these cars? The stock Tamiya front ends do not look very adjustable. Are there companies making better front ends? Are they allowed to run together?
The F-104 front end has camber and RC adjustment, Exotec has a front end hop-up that allows caster change. As F1 is still growing the rules regarding chassis are still up for discussion. Kingpin Front with DD rear has been the mainstay for the last 25+yrs, and would do well to keep things simple
4. It looks like most of the racing is 2s 21.5 blinky. Is that true?
Yes this is the most common
5. Are most people using shorty 2s packs or full size?
Shorty packs are becoming more popular, some racers still prefer standard packs on low grip surfaces
6. What is the most common minimum weight?
There is no weight limit in TCS, or UF1, I believe ROAR & IIC came up with something arbitrary like 1150g?
Thank you,
