Replacement parts for RTF or ARF planes are very expensive. The Hangar 9 wing sets are $59.96, fuselages are $46.71, tail feathers are $26.96

If you cannot rebuild the wood parts from scratch, you’ll likely come out cheaper getting a new plane. There are several trainer ARF models available for $65 to $100.
