If you can strech the budget to $200... you can get a low end 4-ch radio, a MAgnum XL .40, and build a "SPADET-LC40" (Free plans at
www.spadtothebone.com ) And still have a little left over for fuel.
The 4-ch radio will transfer EASILLY to other planes. The Magnum engine will survive several years (unless you smash it in a crash...

) The SPADET is a nice looking trainer.... (and introduces you to the wonderful world of recycling signs to make airplanes. [img]i/expressions/face-icon-small-wink.gif[/img] )
