Description

The short kit comes with two firewalls.  One has notches for the engine rails as shown on the plan, and the other is solid with no notches, for use with a nylon engine mount.  You’ll receive both, so you can make the decision as you build.

When you order the kit, an alternate wing is available with 3/8″ balsa leading edges and 3/16″ square hardwood spars.  The alternate wing is built with leading and trailing edge sheeting and cap strips.  Space the ribs about 3″ apart, and there are no half-ribs (W1 on the plan).

Or you could get this kit with the standard wing as shown on the plan.  Let me know which you prefer.
