Next up is building the cowl. That process begins by building the sub-structure. The sub-structure is simply two balsa rings and four strips of 1/16”x1/8” balsa. Once the sub-structure is complete two layers of 1/32” balsa sheeting are wrapped around the round structure. The nose ring is made from two laminations of 1/8” balsa. The nose ring is shaped using a Dremel tool. After shaping the balsa disk that makes up the back of the nose ring is opened up for the motor. More on that later.
Next on the to do list is setting up the equipment installation in the fuselage.

The cowl sub-structure is simple but quite strong.
Two layers of 1/32" balsa are wrapped around and glued to the sub-structure. Very strong and light.
The nose ring is shaped using a Dremel tool. The marked opeing is cut after the shaping process is completed.
The nose ring is glued to the the cowl structure. The opening shape will accomodate the equipment installation to be discussed later.
