  • Masking tape – Used to protect the surrounding area from the glue and paint sprays
  • Thin CA glue and activator spray – Used to glue and repair small surface damages or cracks
  • Thick CA glue and accelerator spray – Used to glue and repair larger surfaces and areas
  • Covering film or tissue paper – Used to cover and protect the plane’s exterior after repairs are made

In addition to these materials, you may want to invest in some specialized tools, such as a building board or a plane cradle, to help you with the repair process. Some kits and plans for balsa RC planes, such as those found on sites like, may also include the necessary materials and tools.
