			IMPORTANT: This is NOT a beginner plane! If you are not already an intermediate to advanced flyer, do NOT get this plane, you will not be happy. Picture the F-117 as a super stunt plane, not something you want to start out on. If you are new to RC, get a flight simulator and learn how to fly before you attempt to fly anything.

			BEFORE YOU START: Please watch the Instructional videos, view all the pictures, before you start. This way you have an overview of what's going on and will be able to "fill in the blanks" yourself as you go along. After you have read all the instructions, seen the instruction videos, and studied the pictures, if you still have questions please email me and I will help you out.
Part 1 (8:37)					Part 2 (7:35)

		1) Install Carbon Tube

		The idea here is to just score and cut a 3mm groove for the 3mm carbon tube to go into. This way, you still have a 3mm depron joint on the underside of your glue joint.
		When the body is installed later, it will add a lot more strength running front to back.


		2) "45" the Elevons
		Use a straight edge and a razor blade and “45” the elevons. Use some strong tape to put them on.

		3) Mount the Motor
		By drilling a hole and then epoxying in the toothpicks, you're really “bolting” the mount together. Make sure there is no slop between the stick and the GWS mount.

		4) Make Control Rods
		Once the entire mount, motor, and prop are together, epoxy them in place. Your prop will tell you where to put it so it lines up with the prop slot.

		5) Install Servos

		A couple things to watch for, and then you can do this however you like:
		- You want the servos to up close to the motor mount and the push rods to run in a straight line with the elevon hinges. - You want the incretion of the control rod to the elevon to be towards the center of the elevon. This will prevent flutter at high speeds.

		Bend the rods as seen in the picture. Do a dry fit first so you know that it’s all right.
		Glue the push rod to the elevon first and then allow it to line itself and the servo up with the elevon hinge.
		For the zip-ties on the servo arm, I always goop them real good with epoxy once I have them set right. The zip-ties will hold the rod to the servo, and the glue will hold the zip-ties to the servo horn.
				NOTE: This is another example to use HS-56 servos rather than HS 55s. You’ll have to pull all this out if the servo goes out. A 56 servo is going to be overly strong and you will never have to worry about it.
		6) Make Bomb Box (Optional)
		This will take some finagling and working with to get to work just right. Biggest issue is getting the trap door cut away right so it hinges right.




		7) Install Servo Trap Door









		8) Scroll Body Parts
		This is the fun part! There is no measuring here, you simply score from one "corner" to the other.



		9) Tape/Hinge Body Parts
		Start with the big center fuselage first. After that is glued and dried in place then build the side air intakes and nose around it.
				NOTE: Make sure your top hatch will fit right once it’s all dry.

		10) Glue Down Body Parts


		11) Toothpick Reinforcements
		I will put toothpicks inside the front nose and tip of the top hatch. This will make them much stronger and able to stand up to wear and tear.

		12) Hatch Magnets
		I put (4) magnets up front, and (2) magnets and (2) washers in the back of the hatch. The wind wants to pull the front of the lid off.

		13) Install Vertical Tails
		These overhang about ¾” off the back and about ¾” apart from one another.
