Flying Wing Step by Step Build Guide Pro Set-Up

Posted by aerobeez On November - 13 - 2014

Hello pilots and builders and welcome back to another installment of our Step By Step Build Guide series! In this build log, Pete will show the different methods that can be used in building the Aerobeez fun wings. This is a modified Pro Set-Up that shows off some of the ways that you could improve or mod the basic set-up. Certain parts that come with the receiver ready kit will not be used to save weight and improve performance. These flying wings are completely customizable to your own preference.

So, without further ado, let’s start the build!

In this build we will be using the Stinger version of the Flying Wing, but these steps can also be used on the AngreeBee. Bellow you will see what will come out of the box

Step 1: The glue used can be personal preference. The included tube of contact rubber cement works just as well. Pete’s choice of glue for the wing joint is called FoamTac. The adhesive shown in this photo is the same as FoamTac packaged in a different bottle. If you do not use this adhesive, epoxy or CA can be your choice as well.

Step 1 Flying Wing Build

Step 2: Apply the adhesive liberally on one wing halve. Once you have a good coat of glue, press the wing halves together and let the wing joint completely dry before moving to the next step. The box the wing ships in works great as a building saddle. When the wing halves are joined, be sure to check every minute or so a good clean joint. If you are using the included rubber contact cement or FoamTac, check the wing often while the adhesive is drying. Often applying pressure to the wing halves is needed for a tight cured wing joint.

Step 2.1 Flying Wing Build

Step 2.2 Flying Wing Build

Step 3: The wing halves assembled and ready for the next step.

Step 3 Flying Wing Build

Step 4: Locate the flat carbon fiber strip in the parts bag included with the wing. Have a metal ruler or any long flat straight tool ready to cut a slit into the bottom of the wing.

Step 4 Flying Wing Build

Step 5: The flat carbon strip is used as a main wing center spar. This spar should be roughly 8″ in length. The location of this spar is personal preference. Pete’s spar location has been optimized for strength. Make a slit along the ruler approx depth is the height of the carbon main spar strip.

Step 5 Flying Wing Build

Step 6: Insert the carbon main spar into the slit in a vertical fashion starting from one side first. Press the spar until it is flush with the wing or even a be recessed in the wing. When you are satisfied with the spar placement, we will use adhesive to glue the spar in place.

Step 6.1 Flying Wing Build

Step 6.2 Flying Wing Build

Step 6.3 Flying Wing Build

Step 7: This step is a pro build tip and there are different methods you can use. This is Pete’s method. If you choose to use the included rubber contact cement, the wing spar strength will be just as strong as using CA. If you are using rubber cement of FoamTac, you will need to remove the spar, coat the spar on both sides with the adhesive and insert into the wing slot. Pete’s method shown here is using thin CA. He runs the CA along the wing spar and the CA absorbs into the wing and the spar. You can see the CA being absorbed. Run the CA a few times until you can see a wet look on top of the spar. Once you are satisfied with the amount of CA used, let the wing sit until the adhesive dries completely before moving on with the build. NOTE: CA accelerator is not recommended.

Step 7.1 Flying Wing Build

Step 7.2 Flying Wing Build

Step 8: In this step, you can see the suggested mounting position of the winglets “vertical stabilizers”. The suggested position is the bottom of the winglet is flush with the bottom of the wing. Pete chooses a more neutral position for the winglet.

Step 8 Flying Wing Build

Step 9: Use a straight edge ruler and make a center line on the winglets. Making a center line on the wing is optional. Using the rubber cement or FoamTac, apply to the wing tip liberally, line up the winglet and press. The benefit of using these types of adhesive is you can adjust the winglet position to your liking. Pete chooses this more neutral winglet position for better inverted flying performance.

Step 9.1 Flying Wing Build

Step 9.2 Flying Wing Build

Step 9.3 Flying Wing Build

Step 10: Use the wing box as a saddle for the winglets adhesive to dry.

Step 10 Flying Wing Build

Step 11: The Aerobeez wing is now ready for electronics install.

Step 11 Flying Wing Build

Step 12: Bend the elevons with your hand in a up and down motion to approx 30 times or until you are satisfied with the movement. This is to “break in” the foam elevon hinge. This step is to increase efficiency for the servos and allowing a more even control surface movement.

 

Step 12.1 Flying Wing Build

Step 12.2 Flying Wing Build

Step 13: We will now install the servos. Pete choose this servo install orientation for the best geometry from the servo arm to the control surface.

Step 13.1 Flying Wing Build

Step 13.2 Flying Wing Build

Step 14: We will not be using the wood motor box in this pro build. In this pro build, Pete runs the servo wires to the bottom of the wing for a more efficient, better performing and clean looking wing. Make a slot with a sharp hobby knife against the inside vertical area on the servo slot. Press the servo lead through the slot. Note: You do not need to remove any foam. Just a slit is enough to press the servo lead through.

Step 14.1 Flying Wing Build

Step 14.2 Flying Wing Build

Step 14.3 Flying Wing Build

Step 15: Apply the included rubber cement on the servo sidewalls and press into the servo slot. Pro tip: Do not use epoxy or CA for the servo. The rubber cement included breaks free easily in the event you need to replace the servo or servo gears. Epoxy and or CA will adhere the servo permanent.

Step 15.1 Flying Wing Build

Step 15.2 Flying Wing Build

Step 16: Servos installed with leads running on the bottom of the wing.

Step 16 Flying Wing Build

Step 17:  Mark a box area with a marker and a ruler or any straight edged object. Credit cards work great for this step.

Step 17 Flying Wing Build

Step 18: Make a slit “score” the line approx 1/4″ deep or the depth of your receiver. Do not cut all the way through to the top surface of the wing. We are just removing a small portion of the foam to mount the receiver.

Step 18 Flying Wing Build

Step 19: Using a side angle, cut around the lines on all 4 sides. Take your time as this step may need more angle and cutting.

Step 19 Flying Wing Build

Step 20: Remove the foam cut out but do not throw it away. Will use this as a cover for the receiver.

Step 20 Flying Wing Build

Step 21: Remove the amount of foam on the inside of the cut out to fit your receiver of choice. Be careful to not remove too much foam.

Step 21 Flying Wing Build

Step 22: Have your receive ready and plug in the servo leads.

Step 22 Flying Wing Build

Step 23: Plug in the speed control and power on your transmitter then the speed control to center your servos.

Step 23 Flying Wing Build

Step 24: Cut a shallow slit from the servo wire to the receiver area.

Step 24 Flying Wing Build

Step 25: Run the servo wires inside the slit to hide the servo wires. This will give the wing better performance and nice clean look.

Step 25.1 Flying Wing Build

Step 25.2 Flying Wing Build

Step 26: Using a ruler, in a straight line, mark the elevon area closer to the hinge point for the control surface horn. Be careful not to mount the surface horn too close to the hinge point.

Step 26.1 Flying Wing Build

Step 26.2 Flying Wing Build

Step 27: This servo arm as seen in this photo, Pete chooses not to use on the servo. Instead, this servo arm is used in a modification for the elevon control surface arm.

Step 27 Flying Wing Build

Step 28: Use a sharp pair of cutters and clip the servo arm at the root of the 2 long sides.

Step 28.1 Flying Wing Build

Step 28.2 Flying Wing Build

Step 29: Use your hobby knife to cut a vertical slit into the mark on the elevon.

Step 29 Flying Wing Build

Step 30: Test fit the servo horn. When you are satisfied with the position, use epoxy or medium viscosity CA and glue the horn into position.

Step 30.1 Flying Wing Build

Step 30.2 Flying Wing Build

Step 31: Locate the included outrunner motor and parts. Install the motor to the plywood motor mount piece with the 3 phillip head screws included.

Step 31 Flying Wing Build

Step 32: Use a sharp pair of cutters and cut plywood sheet around the motor base.

Step 32 Flying Wing Build

Step 33: Using epoxy or medium viscosity CA, glue the motor base to the center area of the trailing edge in the middle of the wing. Do not be concerned in regards to motor angle or right thrust. Just make sure the motor is centered and level with the wing. Note: Do not use excessive amount of glue. You do not want the glue to enter the motor center. To avoid this, you can remove the motor from the plywood base and use a small piece of tape to cover the plywood motor mount hole. Then install the plywood motor mount to the motor and glue to the wing.

Step 33 Flying Wing Build

Step 34: Locate the pushrod set.

Step 34 Flying Wing Build

Step 35: Cut the carbon fiber pushrod to the correct length. Note: Be sure to not cut the rods too short. Leave enough contact between the carbon rod and the metal pushrod ends.

Step 35 Flying Wing Build

Step 36: Cut the shrink tubing into 4 equal sections.

Step 36 Flying Wing Build

Step 37: Slide two shrink tubings per push rod as shown here. When you are satisfied with the pushrod position, use a small drop of CA to secure the pushrod ends to the carbon rod. When the adhesive has dried, remove the pushrod from the wing and ad more adhesive.

Step 37 Flying Wing Build

Step 38: Use a lighter or heat gun and shrink the tubing to a tight fit on the pushrod.

Step 38 Flying Wing Build

Step 39: Pushrod ready for install on the wing.

Step 39 Flying Wing Build

Step 40: Pushrod installed on the wing.

Step 40.1 Flying Wing Build

Step 40.2 Flying Wing Build

Step 41: Install the propeller mount onto the motor shaft.

Step 41 Flying Wing Build

Step 42: Plug in the speed controller to the motor and receiver. Pete chooses to mount the speed control on the outside of the wing with double sided tape for cooling purposes. You can also choose to cut an area and mount the speed control below the foam in the same manner as the receiver but it is not suggested as the ESC may overheat.

Step 42 Flying Wing Build

Step 43: Tape the piece removed earlier to the receiver area for a clean flush surface. Note: Some foam material may need to be removed from the surface cover for a better fit.

Step 43 Flying Wing Build

Step 44: Apply velcro to the bottom area for the flight battery.

Step 44 Flying Wing Build

Step 45: Install the propeller with the breakaway O rings included. Pro Tip: If you lose break the o rings, you can use a small rubber band and loop it several times for the same result of the O ring.

Step 45 Flying Wing Build

Step 46: Battery mounted and ready for flight. You can also choose to run the battery wires in different fashions if you choose to hide the wire.

Step 46 Flying Wing Build

Step 47: Your modified Stinger or Angry Bee wing is looking clean and ready to take to the sky!

Step 47.1 Flying Wing Build

Step 47.2 Flying Wing Build

Step 48: If you notice that your elevons are not moving free enough to your liking, Pete’s tip is to use a sharp hobby knife and slit the elevons three times on each side using about one inch segments spread along each elevon. One closer to the surface horn but not directly in front. One in the center of the elevon and one before the tip of the elevon. This will allow for a smoother elevon movement. You can also add addition slits as you see fit for your flying style.
