PROTECT YOUR MODEL,YOURSELF & OTHERS...FOLLOW THESE IMPORTANT SAFETY PRECAUTIONS
Your SPECTRA ARF is not a toy, but rather a sophisticated, working model that functions very much like a full-size sailplane. Because of its realistic performance, the SPECTRA ARF, if not assembled and operated correctly, could possibly cause injury to yourself or spectators and damage property.
To make your R/C modeling experience totally enjoyable, we recommend that you get experienced, knowledgeable help with assembly and during your first flights.You’ll learn faster and avoid risking your model before you’re truly ready to solo. Your local hobby shop has information about flying clubs in your area whose membership includes qualified instructors. You can also contact the national Academy of Model Aeronautics (AMA), which has more than 2,500 chartered
clubs across the country. Through any one of them, instructor training programs and insured newcomer training are available. Contact the AMA at the address or toll-free phone number below.

1.Build the plane according to the instructions. Do not alter or modify the model, as doing so may result in an unsafe or unflyable model.
2.Take time to build straight, true and strong.
3.Use an R/C radio system that is in first-class condition, and a correctly sized motor and components (batteries, etc.) throughout your building process.
4.You must properly install all components so that the model operates properly on the ground and in the air.
5.You must check the operation of the model before every flight to ensure that all equipment is operating and that the model has remained structurally sound. Be sure to check nylon clevises or other connectors often and replace them if they show signs of wear or fatigue.
Note: We, as the kit manufacturer, provide you with a top quality kit and great instructions, but ultimately the quality of your finished model depends on how you build it; therefore, we cannot in any way guarantee the performance of your completed model, and no representations are expressed or implied as to the performance or safety of your completed model.
Remember: Take your time and follow directions to end up with a well-built model that is straight and true.
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) 398-8970 or e-mail us at:
productsupport@greatplanes.com.
If you are calling for replacement parts, please reference the part numbers and the kit identification number (stamped on the end of the carton) and have them ready when calling.

INTRODUCTION
The SPECTRA ARF is a very stable and predictable aircraft, allowing pilots of differing skill levels to enjoy it. It is easy to build, flies great, and would be a great selection as your first R/C airplane.
PREPARATIONS
Required Accessories
Items in parentheses (GPMQ4243) are suggested part numbers recognized by most distributors and hobby shops and are listed for your ordering convenience. GPM is the Great Planes brand, TOP is the Top Flite® brand, HCA is the Hobbico® brand.
Minimum three-channel radio with two standard servos
Electronic Speed Controller with BEC
6 or 7-cell rechargeable battery
Building Supplies & Tools
These are the building supplies and tools that are required. We recommend Great Planes Pro™ CA and Epoxy glue.
Pacer Formula 560 canopy glue (PAAR3300)
Plastic wrap or wax paper
Hobby knife and #11 blades (HCAR0105)
1/2" [13mm] Latex foam rubber padding (HCAQ1050)
Phillips screwdriver
Pliers
Great Planes Pro Thin CA (1/2oz) (GPMR6001)
Great Planes Pro Medium CA (1/2oz) (GPMR6007)
Great Planes Pro Threadlocker (GPMR6060)

Optional Supplies & Tools
Top Flite Sealing Iron (TOPR2100)
Top Flite Heat Gun (TOPR2000)
Hobbico single-edge razor blades (HCAR0312)

General Inspection
Remove the fuselage, wing panels, rudder assembly and stabilizer assembly from their individual bags. Inspect all items closely to check for any damage. If any damage is found, contact the place where your SPECTRA ARF was purchased, or Hobby Services, to obtain a replacement for your damaged items. If any of the control surfaces are attached, simply pull them apart and store the hinges in a safe place until it is time to re-attach them.
Your SPECTRA ARF is covered using Top Flite MonoKote® covering. Eliminate any wrinkles you find in the covering by shrinking them away with a heat gun. Then, apply pressure to the area with a covering iron and a hot sock. This will securely bond the covering to the wood so the wrinkles will be less likely to reappear in the future.
Important Building Notes
Several times during construction we refer to the “top” or “bottom” of the model or a part of the model. It is understood that the “top” or “bottom” of the model is as it would be when the airplane is right side up and will be referred to as the “top” even if the model is being worked on upside-down.
