They are giving you good advice in my opinion as well. The Viper with a Thunder Tiger pro 40 is a very nice setup and a handfull of speed. It will also glide in nicely and land very slow. Your are also off the ground straight as an arrow in 3 or 4 feet. You can even use a grass field if you get some better than factory wheels. With your 46, it should be pretty darn quick and will do 180 degree turns in about a half of second, and still be doing over a 100 coming out of the turn. Once trimmed, it's about as stable as anything I've flown. The faster, cleaner planes are great too, but they take a lot more room on landings and don't slow down well. Most club fields don't have enough open area and you will soon destroy it on a landing. The Vipers are cheap and easy to put together in a few nights. I would recommend going with the TT pro 40, so you would be legal for quickie races, just in case you get hooked and want to compete. A Jett or Nelson will be much faster, but they cost a lot more and 428 quickie races are harder to come by, especially on the East coast.

On your first flight, be SURE the elevetor and rudder trim buttons mix on both sides of the V or you will have a wild beast on your hands with no leash. Talk to Mack at Hodges Hobbies in Georgia. He's a great resource and will set you up right.
