Bruce Pickering uses paulownia to build radio-controlled model planes. The fuselage and tail of the De Havilland Beaver (top two images) are made of paulownia. The wings are glass fibre over polystyrene foam. The model has a 3-metre wingspan, and is powered by a 45cc petrol motor.
The second model is a Lockheed Sirius and has a wingspan of 2.5 metres. It is powered by a 35cc petrol motor. The entire model is covered with paulownia machined to 1.5mm thick.
