There is another way to start...

You can get the radio now, something like a Standard Futaba 4-channel (You will eventually need 4 channels to fly Throttle-Rudder-Ailerons-Elevator)

Then, pick up an inexpensive glider. They only require 2 of the servos (rudder and elevator) and are pretty easy to fly. You hook them up to a long piece of surgical tubing which is attached to the ground, and streached like a giant rubberband which will catapult it into the air.

Again, the best advice is to find a few clubs in your area. Most of the members will be glad to help, and in many cases, will have some used equipment that they will sell cheap.

One more thing...

Look up Hobby Warehouse in Richfield. They are the best Hobby Shop in the Twin Cities (or anywhere else for that matter). Stop in there sometime. They are near the Mall of America. Just walking in the place is a sight to behold! AIRPLANES EVERYWHERE!! And great prices too!
