The T-40 comes as a kit for $55. You'll need a roll of Towercote (or Econocote), three wheels, a fuel tank, and some miscellaneous hardware to come up with a plane. The build is pretty simple, and it comes with a good instruction manual. You can also read up on it at the Duraplane site:
www.Duraplane.com . Every model involves some building and the inevitable repairs plus you can count on constant maintenance. The T-40 makes an easy entry into the R/C world for chump change, and it will reward you with its longevity. Unless you're a complete klutz, it'll will take you to your first solo and beyond!
