Team Associated has come out with the RC Cheat Sheets iPhone App, their second iPhone application. The RC Cheat Sheets App is a comprehensive reference guide for every Team Associated car and truck. The app has tuning guides, various calculators, a lap counter, and unit conversion tools.
I went to buy it from the App store on my iPhone, but at $2.99 I had to think again. The reviews in the App store are all pretty good, praising the app for having tons of information and being extremely useful. I think I'll wait to see if it comes down a bit and then check it out.
