Construction plan Saphira

With a wingspan of two metres and a depth of 530 mm, the Saphira flying wing is a striking model simply because of its size. To enable this superb flying model to be used flexibly on slopes and flat terrain alike, the model's construction plan shows two fuselages – one for gliding and one for motorised flight. The construction plan and building instructions are included in issues 04 and 05/2026 of FMT magazine. The construction plan is supplemented by a milling and laser parts kit or the complete wooden kit, as well as an equipment set with motor, controller and servos. This shortens the construction time and increases the enjoyment of building.
