Section 4: Final Assembly Step 5 Step 7 Position the canopy onto the fuselage. Use a felt-tipped pen to trace the outline of the canopy onto the fuselage. Use canopy glue to secure the canopy to the fuselage. . Use masking tape to hold the canopy in position until . the glue fully cures. Step 6 Use sandpaper to lightly sand inside the line drawn on the fuselage. Also sand the inside of the canopy where it will rest on the fuselage.
Control Throws The amount of control throw should be adjusted as closely as possible using mechanical means, rather than making large changes electronically at the radio. By moving the position of the clevis at the control horn toward the outermost hole, you will decrease the amount of control throw of the control surface: moving it toward the control surface will increase the amount of throw; moving the pushrod wire at the servo arm will have the opposite effect.
Pre-Flight Charge both the transmitter and receiver pack for your airplane. Use the recommended charger supplied with your particular radio system, following the instructions provided with the radio. In most cases, the radio should be charged the night before going out flying. Check the radio installation and make sure all the . control surfaces are moving correctly (i.e. the correct direction and with the recommended throws). Test run . the engine and make sure it transitions smoothly from .
Maintaining Your Twist 150 ARF The following is a check list that you should follow . every time you have completed a flying session with . your Twist™ 150. Doing so will keep your aircraft . in the best flying condition. Clean Up If you are flying with a glow engine you will want to clean your Twist 150 before loading it into your vehicle to head home. Use a cleaner such as Windex or 409 and a paper towel to wipe down the exterior of your plane, removing the fuel residue.
Glossary of Terms • Ailerons: Each side of this airplane has a hinged control surface (aileron), located on the trailing edge of the wing. Move the aileron stick on the transmitter left, the left aileron moves up and the right aileron moves down. Moving the left aileron up causes more drag and less lift, causing the left wing to drop down. When the right aileron moves down, more lift is created, causing the right wing to rise. This interaction causes the airplane to turn or roll to the left.
Building and Flying Notes 29
2007 Official AMA National Model Aircraft Safety Code GENERAL 1) I will not fly my model aircraft in sanctioned events, air shows or model flying demonstrations until it has been proven to be airworthy by having been previously, successfully flight tested. 2) I will not fly my model higher than approximately 400 feet within 3 miles of an airport without notifying the airport operator. I will give right-of-way and avoid flying in the proximity of full-scale aircraft.
2007 Official AMA National Model Aircraft Safety Code 5) Flying sites separated by three miles or more are considered safe from site-to site interference, even when both sites use the same frequencies. Any circumstances under three miles separation require a frequency management arrangement, which may be either an allocation of specific frequencies for each site or testing to determine that freedom from interference exists.
