INTRODUCTION
Welcome to the exciting world of EDF (Electric Ducted Fan) 
airplanes! Continuing on the great success of the fi rst pair 
of planes to use the Great Planes EDF unit, the MiGLET 
and the XPD-8, comes a sleek new design with a racing 
paint scheme. Molded in fi nger grips on the underside of the 
plane will allow you or a partner to launch the plane into the 
air, while the thrust of the EDF unit immediately increases 
airspeed to climb to altitude. After the fl ight, the magnetic 
canopy hatch removes easily for a fast battery pack change.
For the latest technical updates or manual corrections to 
the Synapse ARF visit the Great Planes web site at www.
greatplanes.com. Open the “Airplanes” link, then select 
the Synapse ARF. If there is new technical information or 
changes to this model a “tech notice” box will appear in the 
upper left corner of the page.
AMA
 We urge you to join the AMA (Academy of Model Aeronautics) 
and a local R/C club. The AMA is the governing body of model 
aviation and membership is required to fl y at AMA clubs. 
Though joining the AMA provides many benefi ts, one of the 
primary reasons to join is liability protection. Coverage is not 
limited to fl ying at contests or on the club fi eld. It even applies 
to fl ying at public demonstrations and air shows. Failure to 
comply with the Safety Code (excerpts printed in the back of 
the manual) may endanger insurance coverage. Additionally, 
training programs and instructors are available at AMA club 
sites to help you get started the right way. There are over 
2,500 AMA chartered clubs across the country. Contact the 
AMA at the address or toll-free phone number below.

IMPORTANT!!! Two of the most important things you can do 
to preserve the radio controlled aircraft hobby are to avoid 
fl ying near full-scale aircraft and avoid fl ying near or over 
groups of peple.
PROTECT YOUR MODEL, YOURSELF
& OTHERS...FOLLOW THESE
IMPORTANT SAFETY PRECAUTIONS
1. Your Synapse ARF should not be considered a toy, but 
rather a sophisticated, working model that functions very 
much like a full-size airplane. Because of its performance 
capabilities, the Synapse, if not assembled and operated 
correctly, could possibly cause injury to yourself or spectators 
and damage to property.
2. You must assemble the model according to the instructions. 
Do not alter or modify the model, as doing so may result in an 
unsafe or unfl yable model. In a few cases the instructions may 
differ slightly from the photos. In those instances the written 
instructions should be considered as correct.
3. You must take time to build straight, true and strong.
4. You must correctly install all R/C and other components so 
that the model operates correctly on the ground and in the air.
5. You must check the operation of the model before every 
fl ight to insure that all equipment is operating and that the 
model has remained structurally sound. Be sure to check 
pushrod connectors or servo arms often and replace them if 
they show any signs of wear or fatigue.
