Assembly Guide

Manzano Laser Works

The Manzano de Havilland DHC-1 Chipmunk is based on a design developed by Ivan
Pettigrew.The structural design has been updated to take advantage of laser cut parts and to
help reduce the build time.

Construction of this model can be in any order preferred, but this assembly guide has been
organized to follow a suggested build sequence. That sequence begins with the tail surfaces
followed by the wing then the fuselage. This sequence is not critical but does facilitate
construction of the fuselage. Completion of the fuselage depends on having the wing and tail
surfaces available for shaping of some of the parts.

There are three 36” x 80” plan sheets for this model as follows:
Sheet 1 - Fuselage
Sheet 2 - Wing, Stab, Fin/Rudder
Sheet 3 - Sheeting and part layouts not included on the other plan sheets
Materials used in this model include balsa, liteply,plywood, brass tubing, and piano wire. A

formed plastic canopy is also used. Most of the wood and the formed canopy is supplied with
the kit. The builder supplies 3/16” and 1/8” square balsa strip stock, piano wire, brass tubing,
and the hardware needed to complete the model.

The completed model should have a flying weight in the 5 to 6 pound range. To provide a
reasonable power level for handling wind and take offs from rough terrain, a power loading of
at least 70 watts per pound is suggested. That translates to a motor/prop/battery selection that
can deliver at least 420 watts. The battery area of the model can accommodate up to four cell
lipo packs in the size range suitable for this model.
