Construction was of mixed balsa/plywood similar to the Mosquito but the Hornet differed in incorporating stressed Alclad lower-wing skins bonded to the wooden upper wing structure using the new adhesive Redux. The two wing spars were redesigned to withstand a higher load factor of 10 versus 8. Apart from the revised structure, the Hornet's wings were a synthesis of aerodynamic knowledge that had been gathered since the design of the Mosquito, being much thinner in cross-section, and with a laminar flow profile similar to the P-51 Mustang and Hawker Tempest. The control surfaces consisted of hydraulically-operated split flaps extending from the wing root to outboard of the engine nacelles; as on the Mosquito, the rear of the nacelle was part of the flap structure. Outboard, the Alclad-covered ailerons extended close to the clipped wing tips and gave excellent roll control.
