Safety glasses are the best way to protect your eyes. ALWAYS protect your body, especially your hands and fingers when using adhesives, knives, or tools, especially power tools. Do not cut toward exposed skin with hobby knives. Do not place hobby knives on tables or benches where they can roll off or be knocked off. ALWAYS have a first-aid kit handy when working with adhesives, knives, or tools, especially power tools. ALWAYS keep hobby equipment and supplies out of the reach of children. 2

3 Safety in Flying This is NOT a toy! It is a very high-performance RC airplane capable of high speeds and extreme maneuvers. It should only be operated by a competent pilot in a safe area with proper supervision. ONLY fly your aircraft in a safe, open area, away from spectators and vehicles and where it is legal to fly. NEVER fly over an unsafe area, such as a road or street. NEVER fly too close to yourself or spectators. NEVER run your motor inside a house or building with the propeller attached Remove the prop for safety. Required Items CA Glue Thin and Thick Epoxy glue Hobby Knife Small Phillips Screwdriver Set Metric Allen Wrenches Scissors Small Pliers Wire Cutters Masking tape Optional Heat gun Before Starting Assembly Examination Unpack your airplane and examine the components. Check for damage of any kind. If you see any damage, please contact Value Hobby immediately. Covering Your airplane was packed in plastic at the factory without any wrinkles in the covering. You may notice some wrinkles now; more likely, you will notice a few in a day or two or the first time you take the plane out to the flying field. These wrinkles are the result of wood shrinkage and/or expansion. Balsa wood changes size and shape slightly as it is exposed to varying humidity in the air. This is a natural property of balsa wood. As your airplane adjusts to the weather in your part of the world, wrinkles may appear and disappear. Wrinkles may be removed with the gentle application of heat to the covering material on your airplane. The best tool to use is a hobby heat gun. Apply the heat gently: the covering material will shrink as you apply the heat, and this will remove the wrinkles. BE CAREFUL! Too much heat applied too quickly can damage the covering, either by causing it to pull away from the wood at seams and corners or even by melting it. The covering will shrink at low temperature with patient application of heat. Wrinkles in the covering DO NOT affect flight performance. Remove the canopy before attempting to use heat on your covering! The canopy is made of thermo-activated plastic and WILL deform with the application of heat. Do not apply heat to the canopy. 3

Test fit the vertical fin in the fuselage. Check for proper alignment and then glue it with medium CA. Step 3. Insert three hinges in their appropriate slots on the rudder. Verify the alignment and glue them with some drops of thin CA. 9

10 Step 4. Locate the rudder and carefully glue the hinges with some drops of thin CA. 10

11 Section 4: Elevator installation Step 1. Test fit the horizontal stabilizer in the fuselage. It should be centered between the left and right side. Using the wing tube as a guide, measure the distance from the tube to the stabilizer as shown. Make sure this distance is also the same on the left and right sides. Step 2. Trace the outline where the horizontal stabilizer joins the fuselage using a marker. Step 3. Using the outline from the last step, remove the covering over the horizontal stabilizer that goes into the fuselage. 11

12 Step 4. Carefully slide the elevator into the fuselage opening. Step 5. Carefully insert the stabilizer into fuselage opening. 12

13 Step 6. Insert in the elevator into the opening and verify the position and alignment of the elevator with the stabilizer. Then carefully glue the hinges in the elevator with a few drops of thin CA. You will glue the hinges to the stabilizer in the next step. Step 7. Flex the elevators 45 degrees up and down, make sure the elevator can move freely. Then glue the hinges with thin CA. 13
