This is true but being a thrifty person the deals you can find on used aircraft are simply irresistible. For example, If you want a new 40 size glow trainer after buying the ARF, engine, and radio you'll easily spend $400. There are complete trainers all the time on Craigslist that were flown maybe once or twice, the guy lost interest, it sat for five years, and now he'll sell it $150. That's how I got into the hobby, I found a Thunder Tiger trainer that was never even fueled for $120. He even included a fuel pump, starter, start battery, and glow driver for that price. It sat in the seller's basement for 15 years. Thanks to the good people here I got the engine loosened up, put in new batteries for the TX and RX and was flying for well under $200.
