BATWING
i
s a flying wing of Christian Vogel in classic wood construction. A model with a very
large field of application, where the fun factor is never too short.
The particularities:
•
laser-cut all-wood construction
with dovetailed and weight-optimized
•
component-transport friendly due to two-piece wing with removable
•
winglets.
•
Surface protection by locking mechanism
•
optionally with motor nacelle for electric drive
The kit:
The wing is constructed with an intro leading edge, pine beams, balsa moldings, balsa planking and
various plywood and caiba plywood parts. The surfaces are constructed using a Depron stencil. The
laser-cut ribs are accurately positioned and positively positioned with the support feet in the
auxiliary template which allows a structure without a blueprint. The surface connection is handled
by a 10 x 2 mm CFK profile. The kit includes - in addition to the laser-cut and numbered
components - all articulated and small parts. Not included in the kit are adhesives, iron-on film and
RC components.
