INTRODUCTION

Congratulations! Thank you for purchasing the Great

Planes ElectroStreak! Tom Stryker's original design for this
airplane was first featured in the November, 1987 issue of Model
Aviation magazine. We built this airplane "just for the fun of it",
and we were so impressed with its performance on our standard

"Thrustmaster" motor, we knew it would be a success as a kit!

During the testing process, the new Goldfire motor was devel-
oped, and we found this motor to be ideally suited for the
ElectroStreak, due to its tremendous power.

This is one of the very few easy to build electric-

powered airplanes in kit form that really does provide exciting and
satisfying acrobatic performance without the need for expensive

cobalt motors or exotic building materials. It is a very smooth and
stable flier, yet it will perform all basic pattern maneuvers, such

as rolls, inside and outside loops, snap rolls, spins, inverted flight,
Immelmans, hammerheads, Cuban 8's, and many others.

While not a beginner's plane, the ElectroStreak is great

for the intermediate or advanced flyer who wants real perform-
ance, with the quiet convenience of electric power.

Please Inspect all parts carefully before starting to

build! If any parts are missing, broken or defective, or if you
have any questions about building or flying this airplane,
please call us at (217) 367-2069 and we'll be glad to help. If you
are calling for replacement parts, please look up the part
numbers and the kit identification number (stamped on the end
of the carton) and have them ready when calling.

PRECAUTIONS

1. You must build the plane according to the plans and

Instructions. Do not alter or modify the model as represented by
the plans, as doing so may result in an unsafe or unflyable modeL

2. You must take time to build straight, true and strong.
