the summer of 1998, we had several drawings on a paper napkin, 10 feet
of gutter pipe, and a sheet of corrugated plastic sign
board. With a very basic aerodynamic knowledge and some
creativity, we built our first SPADMany
planes and lots of trial and error later, we have seen the SPAD
go from the ultra-simple 3-channel Dogfighter (not available
any longer), To the hot flying 4-channel Dominator and Demon and
the even-hotter 3 channel Dagger & Dart! Now it is your
turn to be creative! You've got "stand off scale" and "sport
scale" and the latest craze "profile scale". We would like to
introduce you to "gutter pipe scale!" When we developed the Demon, we noticed it had the sleek
lines of a WWII era fighter. It didn't take us long to take our
basic Demon design, Do a little re-shaping, and the GPS was born!
The possibilities are endless,
so we decided to offer you several
suggestions, and let your preferences and imagination take it from
Creating a SPAD GPS from Demon plans:
1. Choose your favorite WWII fighter aircraft, and choose the Coroplast ® color(s) that you think will do it justice.
2. Shape the elevator and rudder to resemble the real plane. You may wish to reshape the entire tail feathers, making sure the total square inches remains approximate to the original Demon tail feathers.
3. Using the dimensions shown on drawing 8, taper the lower wing trailing edge, when laying out the wing. Also
shape the wing tips to your desires. Since the wing top panels
are trimmed to match during construction, they
will take care of themselves, when following the building procedure.
NOTE: The spar location remains the same IN RELATION TO THE WING LEADING EDGE!
4. If you are building a GPS with a squared off type wing tip (such as a P-51) simply add a Coroplast ® "cap" to the tips upon completion of the wing.
5. Trim the ailerons to match the contour of your wing.
6. Now for the most important step! Upon completion of your GPS, add as many stickers as possible specific to your chosen aircraft! You may even want to add a Pop bottle cowl!
now have a really cool looking airplane, with the same hot
performance of the original Demon! If you have access to a scanner
or digital camera, please e-mail us a
picture of your GPS, and we may use it
on our web site!
May we some day meet in the skies over the Pacific, or perhaps over the English Channel on D-Day!
