Wooden laser parts set miniArrow

In 2017, FMT plan designer Gerald Perschler designed the Arrow flying wing and has been delighted by its outstanding flight performance ever since. As the one-piece wing, with a wingspan of 1.6 m, was often too unwieldy for everyday use, he has now developed the miniArrow – a slightly smaller version with a split wing – as a plan supplement for FMT. The challenge was to construct a swept flying wing using a ribbed structure with a profile thickness of approx. 8.5% that was sufficiently torsion-resistant given the shallow wing depth. This was achieved using a closed D-box. With the recommended motorisation, the miniArrow can climb vertically indefinitely and can also handle full throttle. The construction plan and building instructions are included in issue 06/2026 of FMT magazine. The construction plan is supplemented by a laser parts kit. This shortens the construction time and increases the enjoyment of building.
