I'm based from KGVL, Gainesville GA with an RV-12. I am one of the people of which Scott Millhouse refers. It's a short flight for me to Chattanooga and I would love to give you a demonstration of the RV-12 flight characteristics. The offer of a tower tour is very interesting, never done that before and would like to take you up on that. However I am out of the country now, so if you can wait a few weeks I will contact you when I am available. If you get a ride before I get home don't wait for me. I haven't flown in the -10 yet, but the-12 is pure joy compared to the spam cans. Can't go wrong with any of the RV choices ,as long as you define your mission. Hope we can get together!
