No one that I know of in recent years has done more to promote model aviation both in person and over the Internet than Darcy Whyte, the designer of the “Squirrel” rubber powered free flight model airplane.
The Squirrel design is so simple yet its’ design is ingenious in that it can be built so quickly and helps novice builders avoid many problems common to other beginner airplanes.
I have never met Darcy in person as he lives far away in Ottawa Canada but we converse regularly via the Internet. Darcy Whyte is a software developer specializing in Social Media and Internet systems, his model aviation website has been a great candidate for experimentation in honing his Internet presence. His website URL is http://www.rubber-power.com.
Darcy has provided most of the pictures for this article and has been wonderful about answering my questions. Please pass the link to this article on to anyone that might be interested.
The Ideas That Became the Squirrel

Middle picture - Darcy experimented with tip dihedral before trying the winglets. Left picture - He tested the winglets in a sheet balsa plane. Right picture – at this point he was building by pinning to building board but later glued balsa directly to tissue.
Pictures from the early prototype building.
Left picture –winglet eliminates the need for dihedral, middle picture - center section is flat which makes for easier building and less breakage. Right picture - a really novel feature that is used with the vertical fin and stabilizer is to use only a leading edge of balsa and no support for the tissue on the trailing edge, this eliminates at least two additional pieces of balsa for each surface.
Left picture – popular AMA Cub plane uses dihedral, wing halves angle upward from the center. Middle picture – with dihedral joint wings often break in the center joint. Right picture – AMA Cub stab requires three pieces of balsa with angle joints.
The website for the Squirrel is a wonderful resource for building information, ordering Squirrel kits, and interesting information about model aviation.
Building the Squirrel

Left picture – kit components. Middle picture – Darcy delivers Squirrel kits by motorcycle in his local area. Right picture – a box of Squirrel kits.

Novice builders often have trouble cutting and fitting angled joints but the Squirrel has no angles in the balsa joints.

The Squirrel is built with fast drying craft glue and glue stick which are easy to find, dry relatively fast, and is safe to use.

The Groups That Build Squirrels
The Squirrel model plane has been popular with scout groups throughout the world.


Darcy has given speeches to professional groups such as inventors and creative thinkers about design, manufacturing the kits, and marketing.

Left Picture - one of Slater’s happy classes that built Squirrels. Middle Picture – Darcy and Slater’s son build Squirrels. Right picture – Slater and Darcy.
During the summer of 2009 Darcy visited Slater Harrison who's a school teacher in Pennsylvania who has been building Squirrel model airplanes as part of his science classes. They met on-line when Slater discovered the Squirrel design and started to build them with his students.
Left picture - Slater holds a “walk along glider”, glider rides on a wave of air provided by a person walking with a piece of cardboard. Middle picture – this glider was built almost entirely from paper. Right picture – Slater prepares to release the glider and begin walking.
Darcy has brought his Squirrel model airplane design before more diverse groups than anyone I know of. He has managed to combine model airplane building, adult beverages, and socializing to coed groups in the local pubs of Ottawa.
Darcy has been building model airplanes with a variety of groups for many years, in the above pictures he had not yet perfected his Squirrel design at this session for nursing home group.
Several people have sent Darcy pictures and descriptions of how they have modified the Squirrel design including biplane versions and Squirrels that are much larger. See website Gallery for further details.
Final Note: Darcy is working on educational materials for teachers.
