Wing Assembly 2. Slide the remaining wing panel onto the tube. The two wing panels will fit tightly together. 3. Slide the dowels at the leading edge into the holes in the fuselage as shown. Required Parts Fuselage Wing panel (right and left) Aluminum wing tube #4 washer (2) 4-40 x 1/2-inch socket head screw (2) Required Tools and Adhesives Ball driver: 3/32-inch 1. Locate the aluminum wing tube and slide it into the hole in the wing root of one of the wing panels.
4. The wing will fit tight against the fuselage when installed. Stabilizer/Elevator Installation Required Parts Fuselage w/wing assembly Stabilizer Required Tools and Adhesives Ruler Felt-tipped pen Sandpaper Painter's tape 6-minute epoxy Mixing stick Paper towel Mixing cup Rubbing alcohol Hobby knife w/new #11 blade 8 1. Locate the horizontal stabilizer. Use a ruler to determine the center of the stabilizer. Use a felt-tipped pen to mark the center of the stabilizer. 5.
2. Mark the center of the tail boom inside the boom using a felt-tipped pen. 4. With the wing mounted to the fuselage, use a long ruler to measure the distance from the wing tip to the stabilizer tip as shown in the drawing. Carefully adjust the stabilizer until both measurements are equal. a a 3. Use painter's tape to secure the stabilizer to the fuselage.
Important: Use light pressure when cutting the covering to prevent cutting into the stabilizer. Cutting too deep will weaken the stabilizer and could cause it to fail in flight. 5. Use a felt-tipped pen to transfer the outline of the fuselage onto the top of the stabilizer. 10 7. Reposition the stabilizer and connect the bend from the elevator pushrod to the elevator control horn. The wire will enter the horn from the side closest to the fuselage. 6. Remove the stabilizer from the fuselage.
8. Step back and view the airframe from roughly 8-10 feet (2-3 meters) to check the alignment of the stabilizer to the wing. If they are not parallel to each other, lightly sand the fuselage where the stabilizer mounts to correct the alignment. Fin/Rudder Installation Required Parts Fuselage Skid Fin/rudder Required Tools and Adhesives Felt-tipped pen Painter's tape Mixing cup Hobby knife Sandpaper Paper towels 6-minute epoxy Square Mixing stick Medium CA Rubbing alcohol 1.
2. Use a felt-tipped pen to transfer the edge of the fuselage onto the bottom of the fin. 3. Use a felt-tipped pen to trace the outline of the fin on the top of the fuselage. 4. Use sandpaper to remove the paint from the top of the fuselage. This is necessary to provide a bonding surface between the fin and fuselage. Hint: Use tape to outline the area to sand to prevent removing paint from the surrounding area.
5. Use a hobby knife with a new #11 blade to remove the covering from the bottom of the fin. Important: Use light pressure when cutting the covering to prevent cutting into the fin. Cutting too deep will weaken the fin and could cause it to fail in flight. E-flite Ascent PNP Assembly Manual 6. Reposition the fin and connect the rudder pushrod to the rudder control horn. The bend will enter the horn from the side of the horn closest to the stabilizer.
8. Use 6-minute epoxy to glue the fin to the fuselage. 10. Use a felt-tipped pen to trace the outline of the of the skid on the bottom of the stabilizer. 9. Use painter's tape to keep the fin in position and square to the stabilizer while the epoxy cures. You may use rubbing alcohol and paper towels to clean up any squeeze out during this procedure. 11. Use a hobby knife with a new #11 blade to remove the covering from inside the lines drawn in the previous step.
12. Use medium CA to glue the skid to the bottom of the stabilizer. Receiver Installation Required Parts Receiver Motor battery Hook and loop tape Fuselage assembly Required Tools and Adhesives Phillips screwdriver: #1 E-flite Ascent PNP Assembly Manual 1. Use a #1 Phillips screwdriver to remove the two screws that secure the canopy to the fuselage.
2. Plug the elevator servo, rudder servo and speed control leads into the appropriate ports of the receiver. On a model that uses rudder and elevator control, it is common to plug the rudder servo into the aileron port. 3. Use the supplied hook and loop tape to attach the receiver inside the fuselage. 4. Install the motor battery inside the fuselage. Place the hook and loop tape on the battery and battery tray to keep the battery from moving forward or backward in the fuselage.
Control Throws 1. Turn on the transmitter and receiver of your Ascent 450 BL Park Glider PNP®. Check the movement of the rudder using the transmitter. When the stick is moved right, the rudder should also move right. Reverse the direction of the servo at the transmitter if necessary. 2. Check the movement of the elevator with the radio system. Moving the elevator stick down will make the airplane elevator move up. 3. Use a ruler to adjust the throw of the elevator and rudder.
Range Test Your Radio 1. Please consult your radio instructions for complete range testing instructions. 2. Double-check that all controls (aileron, elevator, rudder and throttle) move in the correct direction. 3. Be sure that your transmitter batteries are fully charged, per the instructions included with your radio.

Glide Testing Your Ascent PNP We strongly recommend that before you fly your new Ascent, you first perform a test glide. Pick a flat spot that has soft, tall grass and is free from obstructions. You first want to check out the Ascent’s performance but also check your performance as a pilot. It also allows you to make corrections to any building or control defects that may have been overlooked. The test glide should be done with an assistant on a calm day.
Thermal Soaring A key component to soaring is the air mass the park glider flies in. Also, there is an energy source producing lift, either a warm air thermal (thermal lift), or the wind rising as it meets an obstacle such as a hill or a line of mountains (ridge lift). We will limit our discussion to describing thermal soaring. We will be using the electric motor to launch our park glider to altitude.
Sometimes the wind will cause the thermal to bend or break, causing a warm air bubble that slowly travels downwind as it rises. Thermals can vary in strength, rising at speeds of a few hundred to over a thousand feet per minute. Thermal Form (Column) As you are flying your Ascent, watch it carefully. If you were in a full-size glider, you would be able to feel the "bump" of entering a thermal. Now you must depend on signs the glider gives as it approaches or enters a thermal.
Executing a 180-degree turn The second method is to make a wide 180-degree turn back into the thermal. Flying the Core of a Thermal Once in the thermal, you will need to try to stay in the center of the lift. Slow down by increasing the up elevator "trim" until the park glider is just above stall (minimum sink) speed. Make easy banking turns to find the area of highest lift (thermal core). When you have found the core of lift, tighten the turns to stay within the core of highest lift.
In-Flight Adjustments for Performance and Conditions • Pitch Attitude • Minimum Sink Speed • Maximum Lift/Drag (L/D) Speed Pitch Attitude To determine the Ascent’s airspeed, you will have to watch carefully for its pitch attitude. Pitch attitude can best be described as the amount (degree) the nose of the aircraft is above or below a line relative to the horizon. The angle of attack term is used to describe the angle between the chord (width) of the wing and the direction the wing moves through the air.
Minimum Sink Speed In our discussion of thermals, we know sink is the cooler air moving downward to replace the warm air that is rising. Minimum sink speed is the speed at which a park glider loses altitude most slowly. As the term then implies, minimum sink speed gives the glider the maximum amount of time aloft from a given altitude. This is the speed to fly at when you are circling in thermals, or whenever you need the maximum lift the glider can produce.
2008 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.
