Guillow's is the recognized leader in quality scale balsa model airplane kits. Our model construction kits are the last word in scale realism for the super detail fan and light weight for those who build and fly. Build-N-Fly models are designed to take a builder with little or no experience in model airplane building from the very basic all balsa "Trainer" glider to the "Fly Boy" a box fuselage, stick & tissue constructed and rubber powered model.
