RV-4 (350) 1:8 Scale, Laser-cut Kit

From: $139.00

We developed the 1:8 Scale RV-4 for publication in balsabuilder magazine.  The 35 in. span RV-4 (350) is a is a complete redesign of our classic brushed speed 300 kit offering.  We refreshed the design to increase the models appeal to both kit and traditional plans builders alike.  We think the updated RV-4 is a great improvement over the original, with a reduced parts count and easier to handle materials, the structure remains light, sturdy, and ridiculously simple to frame – this makes the balsabuilder version of our classic easier to handle, sturdier, and more refined.

We are excited to offer the RV-4 in full kit form.  This comprehensive kit offering includes a full complement of laser-cut ribs, formers, and shape parts along with: balsa wood strip stock, plans, construction article, pre-formed landing gear, canopy, cowl, wheel pant kit, and thorough hardware package.
