FYI, we can get the same Pilot RC plane, all up (all equipment included and installed) in a 37.5% (121" DA 150) from Chief custom built by Dave Sullivan for $6750 or $55.79 a wingspan inch all up.. Or any others as he is a custom builder. His prices are pretty good though as is the price for the whole package IMO. Not saying there aren't bigger and more expensive. Just throwing it out there as a discussion thing.

Most Small Glow Airplanes: $200-$400

50cc Size Airplanes: $500-$750

100cc Airplanes: $800-$900

150cc and Larger: $1000-$1500

Some composite airplanes require more time and depending on the manufacture can cost a little more.
