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 shown.

PROTECT YOUR MODEL, YOURSELF
& OTHERS...FOLLOW THESE
IMPORTANT SAFETY PRECAUTIONS
1. Your Great Planes Extra 300SP .46 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 Great Planes Extra 300SP .46 ARF, 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 use an R/C radio system that is in fi rst-class condition and a correctly sized engine and components (fuel tank, wheels, etc.) throughout the building process.
5. You must correctly install all R/C and other components so that the model operates correctly on the ground and in the air.
6. You must check the operation of the model before every fl ight to ensure that all equipment is operating and that the model has remained structurally sound. Be sure to check clevises or other connectors often and replace them if they show any signs of wear or fatigue.
We, as the kit manufacturer, provide you with a top quality, thoroughly tested kit and instructions, but ultimately the quality and fl yability of your fi nished 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 the instructions to end up with a well-built model that is straight and true.
DECISIONS YOU MUST MAKE
The recommended engine/motor size range for the Great Planes Extra 300SP .46 ARF is noted on the cover of the manual. Your decision basically comes down to personal preference and what your fl ying style is. Glow engines tend to be lighter weight and have lower initial cost. However, they create oil residue on the underside of the airplane and require the ongoing purchase of fuel. Electric motors will cost more initially, but are the easiest to operate and allow for the cleanest cowl installation. If an engine in the upper end of the size range is used, remember that this is a scale model that is intended to fl y at scale-like speeds, so throttle management should be practiced.
If using the RimFire 42-60-480 brushless electric motor, you must also purchase a 60A brushless ESC capable of handling 60A at 30V. The Great Planes SS-60 High Voltage Brushless ESC (GPMM1850) is a suitable ESC for this motor.
7. If you are not an experienced pilot or have not fl own this type of model before, we recommend that you get the assistance of an experienced pilot in your R/C club for your fi rst fl ights. If you’re not a member of a club, your local hobby shop has information about clubs in your area whose membership includes experienced pilots.
8. While this kit has been fl ight tested to exceed normal use, if the plane will be used for extremely high stress fl ying, such as racing, or if an engine larger than one in the recommended range is used, the modeler is responsible for taking steps to reinforce the high stress points and/or substituting hardware more suitable for the increased stress.
9. WARNING: The cowl and wheel pants included in this kit are made of fi berglass, the fi bers of which may cause eye, skin and respiratory tract irritation. Never blow into a part (wheel pant, cowl) to remove fi berglass dust, as the dust will blow back into your eyes. Always wear safety goggles, a particle mask and rubber gloves when grinding, drilling and sanding fi berglass parts. Vacuum the parts and the work area thoroughly after working with fi berglass parts.
Glow Engine Accessories
These are the items shown in the manual that were used with the O.S.® 81FS-a (OSMG0981). If using a different glow engine the same or similar items will also be required.

There may be many different battery and propeller combinations available that will work well with the recommended brushless RimFire motor for this model. However, the following setup is one that has been tested with the Great Planes Extra 300SP .46 ARF and has proven to have the best overall performance.
Two ElectriFly
(GPMP0623) These batteries will be connected in series. This is what is refered to as a “6S” confi guration, because it is comprised of two 11.1V LiPo battery packs, each consisting of three individual 3.7V LiPo cells connected in series.
Great Planes ElectriFly Series Deans
adapter (GPMM3143)
IMPORTANT: Before experimenting with different battery combinations and connecting multiple battery packs with adapter plugs, refer to the Battery Precautions on page 22.
If using LiPo batteries, a charger specially suited for charging LiPo batteries is required. The Great Planes PolyCharge™ 4 (GPMM3015) is recommended for charging the batteries recommended. The PolyCharge 4 will charge up to four LiPo batteries simultaneously. If using the PolyCharge 4, a 12 volt source will also be required for powering the charger. If you plan on charging four 3,200mAh batteries simultaneously, a power source capable of delivering at least 12.8A is required. A suitable 12V auto battery could be used, or a portable source capable of converting 120V AC to 12V DC such as the Rivergate 15A DC Bulldog Power Supply (RHCP2015) is suitable. If charging only three 3,200 batteries simultaneously, the Hobbico® 12 Volt Power Supply (HCAP0250) is also suitable.

IMPORTANT BUILDING NOTES
Covering Tools
A Top Flite® or Coverite 21ST Century® model airplane covering iron with a protective covering sock will be necessary for tightening any covering on the model that may have loosened or formed wrinkles between the time of production and your purchase. The Coverite 21ST Century iron is preferred as it has a longer cord and a rounded, contoured shoe. A trim iron is not as much of a necessity, but would still be very handy for sealing the edges down inside servo openings and other small areas.

• There are two types of screws used in this kit:
Self-tapping screws are designated
by a number and a length. For example, #6 x 3/4" [19mm].
Machine screws are designated by a
number, threads per inch, and a length. For example, 4-40 x 3/4" [19mm].
Socket Head Cap Screws (SHCS) are
designated by a number, threads per inch, and a length. For example, 4-40 x 3/4" [19mm]
• When you see the term test fi t in the instructions, it means that you should fi rst position the part on the assembly without using any glue, then slightly modify or custom fi t the part as necessary for the best fi t.
• Whenever the term glue is written you should rely upon your experience to decide what type of glue to use. When a specifi c type of adhesive works best for that step, the instructions will make a recommendation.

• Whenever just epoxy is specifi ed you may use either 30-minute (or 45-minute) epoxy or 6-minute epoxy. When 30-minute epoxy is specifi ed it is highly recommended that you use only 30-minute (or 45-minute) epoxy, because you will need the working time and/or the additional strength.
Photos and sketches are placed before the step they refer to. Frequently you can study photos in following steps to get another view of the same parts.
• The Great Planes Extra 300SP .46 ARF is factory-covered with Top Flite MonoKote fi lm. Should repairs ever be required, MonoKote can be patched with additional MonoKote purchased separately. MonoKote is packaged in six-foot rolls, but some hobby shops also sell it by the foot. If only a small piece of MonoKote is needed for a minor patch, perhaps a fellow modeler would give you some. MonoKote is applied with a model airplane covering iron, but in an emergency a regular iron could be used. A roll of MonoKote includes full instructions for application. Following are the colors used on this model and order numbers for six foot rolls.
Yellow (TOPQ0203) Jet White (TOPQ0204) Metallic Blue (TOPQ0402) Metallic Platinum (TOPQ0408)

SHRINK THE COVERING
Examine the airframe for wrinkles in the covering or areas
where the covering isn’t adhered to the structure. Where necessary, use a covering iron with a protective covering sock to shrink any wrinkles and get the covering bonded to the framework—use an iron temperature setting lower than you normally would for MonoKote—around 300° – 325° F is recommended. And use care over seams. If too much heat is applied over seams and edges the covering may pull away. Note: Lighter fl uid can be used to remove any adhesive left from the masking tape holding the control surfaces.
3. Insert one half of each hinge into the aileron.
BUILD THE WINGS
Hinge the Ailerons
1. Drill a 5/64" [2mm] diameter hole, approximately 1/2"
[13mm] deep, in the center of each hinge slot on both the wing and the aileron. This will allow the CA glue to properly wick through the entire hinge.
4. Starting from the tip of the wing, insert the other half
of the hinges into the wing. Once all of the hinges have been inserted into the wing, gently slide the wing from left to right until the leading edge of the aileron is snug with the trailing edge of the wing. The T-pins should provide a space of approximately 3/64" [1.2mm] between the aileron and the wing. Note: Do not force the hinges into the wing. If a hinge does not easily slide into place, simply remove the aileron. Use a hobby knife with #11 blade to widen the hinge slot until it slides into place snugly.
2. Temporarily insert a T-pin into the middle of each hinge.
This will be used to properly align the hinge when mating the aileron to the wing.
5. With the T-pins in place, slide the aileron until it sits
fl ush with the tip of the wing. Remove the T-pins and apply 6
888
drops of thin CA glue to each side, of each hinge. At this point do not fl ex the hinge. Wipe off any excess CA that appears in the gap and set the wing aside. Repeat steps 1-7 for the other aileron and wing half. Allow the CA to cure without the aid of activator. Once the CA has cured move the aileron back and forth to be sure the hinge is free.
Install the Wing Dowels
1. Locate the four 1/4" x 1" [6 x 25mm] dowels. They are the
four longer dowels included in the hardware pack. Remove the servo hatches from the underside of each wing and set them aside. Mark the center of each wing dowel.
Install the Aileron Servos
1. Locate the servo hatch from the underside of the wing
that was set aside.
2. Test fi t the wing dowels by placing them into the holes
in the wing, up to the mark you have made.
During construction there will be several occasions where epoxy cleanup will be necessary. Instead of wasting whole paper towels, stack three or four paper towels on top of each other and cut them into small squares. This will conserve paper towels, and the little squares are easier to use. For epoxy clean up, dampen the squares with denatured or isopropyl (rubbing) alcohol.
2. Trim away the covering from the servo hole as shown. If
using Futaba S9650 servos for the ailerons, you will need to trim away the side mounts as shown.
❏ ❏ 3. Locate the four 3/4" x 1/2" x 5/16" [19 x 13 x 8mm]
blocks of wood. These will be used to hold the aileron servos to the servo hatch. Hold the wood blocks to the servo, making certain the block overhangs the servo on the side of the servo that will be mounted to the hatch. Using a marker, mark the location for the servo screws as shown.
