Printing

RC_Instructions.png 
Printing From Home
- To print from home, download the “Tiled PDF” version from your RCPowers.com online account.
- Click the link to download. Then search your computer’s downloads for the “Tiled PDF” file.
- It’s best to do a “test print” to insure your computer and printer connection is working properly.
- The plans will fit on the standard 8.5x11 letter sized and A4 paper.
- Print at “actual size” or 100%. Use the “scale” on the plans to double check that the size is correct.
- Use a straightedge and razor blade to cut on the inside of the black borders.
- Cut only the bottom and right margins of each page.
- Overlap and line up each page using the adjacent pages’ black borders.
- Tape them all together with clear Scotch Tape.
- Using the layout page and page numbers as a guide, tape all pages together to create the life size plans.

Printing From Print Shop
- The advantage of printing from a print shop is you skip having to cut and tape pages to get your plans.
- To print from a print shop, download the “Untiled PDF” version from your RCPowers.com online account.
- Click the link to download. Then search your computer’s downloads for the “Untiled PDF” file.
- Copy the “Untiled PDF” file to a USB thumb drive and take it to your print shop (FedEx/Kinkos, etc.).
- Tell the print shop to print the file at “100% on black and white”.
- Use a ruler and the scale provided on the prints to check for 100% size accuracy.

Plans to Foam

RC_Instructions2.png 
Spray Glue Down Plans
- Use spray glue to apply a very thin mist of glue evenly on the foam. Test on some scraps first.
- Lay down the paper plans onto the area with the glue, and use your hands to smooth out any wrinkles.
- The paper can be pulled off later like a sticker after you finish cutting the foam parts out.
- Wipe some hand sanitizer onto the paper if you’re having any trouble pulling it up.
- The rubbing alcohol in the hand sanitizer will soak through the paper and break up the spray glue.

Cut Out Foam
- Using a straightedge and razor blade cut out all the parts on the solid lines.
- Cut out all the “inside” notches for servo and control horn placement.
- Leave all the dotted lines alone for now, those are for “scoring and folding” later.

Score-Fold

RCP-2.png 
Score On Dotted Lines
- Scoring is when you take your straight edge and razor blade and lightly run it across the surface of the foam.
- Using just the weight of your hand and blade (applying no downward pressure), just skim across the top.
- The goal is to cut approximately half way through the 6mm foam (just less than 3mm).
- After scoring along all the dotted lines, now gently bend the foam along the score lines.
- If you score too deep this is ok, these parts will be reinforced later with strapping tape.
- Bend the parts to 45 degrees using the score line as a hinge.

Reinforce Score Lines With Strapping Tape
- When all the scoring is complete, next run strapping tape along the inside fold.
- The strapping tape helps to give the parts lasting strength.
- Our general rule is to apply about 2 inch pieces of tape with 1 inch gaps in between.

Combine Wing Plate Pieces

RC_Instructions3.png 
Combine Wing Plate Pieces
- Double check that the two wing pieces butt together smoothly, trim or sand if needed.
- Glue them together using epoxy and let it dry for 10 minutes.
- Put masking tape on the top and underside of the parts and tightly “pull” them together.
- Apply this masking tape every 6 inches along the length of the glue joint to insure a tight joint.

Carbon Tube

RCP-3.png 
Cutting Carbon Tube
- The exact length of the 3mm carbon tube is on your PDF plans.
- WARNING: Do not breathe the carbon dust when cutting. Treat it as you would fiberglass.
- Carbon fiber also splinters easily so do not attempt to “snip” it.
- For best results, use a very fine tooth cutting tool such as a scroll saw or dremel.
- Wrap masking tape around where you’ll cut (this will help catch dust and keep the carbon from splitting).
- Then wrap the area you are cutting with a wet paper towel to trap more of the dust.
- Be sure to cut the carbon tube in a well ventilated area and use a dust mask.

Score-Pluck For 3mm Carbon Tube
- Trace out where the carbon tube goes (see your PDF plan for exact location).
- You want to create a 2mm “canal” for your 3mm tube to fit tightly into.
- Using the “scoring” technique you used previously, simply score along the lines where the carbon tube goes.
- Use a 2mm standard screwdriver to “pluck” out the top of the foam. Try not to pluck more than 2mm deep.
- Run your carbon tube back and forth in the groove to compress the foam to fit.
- Dry fit the carbon tube before gluing to insure it’s flush with the surface.

Glueing 3mm Carbon Tube
- Run masking Tape along both sides of the carbon fiber tube canal to protect the foam from glue spillage.
- Slather epoxy thoroughly and evenly through the canal.
- Press the carbon tube firmly into the canal.
- Cover the tube with masking tape.
- Place flat weights (such as large books) on top while drying.
- Wait 20 minutes for optimum drying time and then peel the tape off.

Control Surfaces

RC_Instructions4.png 
Bevel Control Surfaces
- The control surfaces (elevons) are attached and hinged to the plane using strapping tape (see step below).
- The bottom side of the control surface hinge line needs a bevel so the parts can move freely.
- We recommend practicing the beveling step on a piece of scrap foam first.
- Using a razor blade and straight edge, cut a 30 degree angled bevel along the jointed edge as pictured.
- Repeat this process on the opposite edge as pictured.

Hinge Control Surfaces
- Apply the strapping tape along the top of the joint as pictured.
- Our general rule is to apply about 2 inch pieces of tape with 1 inch gaps in between.
- Make sure to have the threads in the tape running parallel with the hinge (horizontally).
- Next, carefully apply strapping tape along the bottom of the joint as pictured.
- Be sure to have the control in the “open” position while applying to insure full movement.
- If needed, tear off the tape and take another try until your controls look as pictured.
- The plane will flex some during flight so double check that the elevons can move freely without rubbing.
- Trip ⅛ inch of foam off from the inside of the elevon if needed to insure everything moves freely.

Motor Mount

RC_Instructions5.png 
Motor Mount Support
- The prop needs to be in about the middle of the prop slot (not too close to either edge).
- It’s ok to custom cut your prop slot larger or into a different shape if needed.
- First dry fit your entire motor, prop, and mount assembly to see how it all fits before screwing and gluing.
- You can use 1, 2 or no motor shims to adjust the fit to the size of motor you have.
- Epoxy down mount using masking tape and pins to hold it. Make sure the mount dries straight.
- Now seal with hot glue. You want the motor mount “too strong” not “strong enough”.

Install Battery Velcro

RC_Instructions6.png 
Install Battery Velcro
- The 11.1v Lipo flight batteries are velcroed to the inside compartment of the plane.
- This allows you to change out the flight batteries quickly at the flying field.
- Stick the “hook” side of the adhesive velcro to your flight batteries.
- Stick the “loop” side of the adhesive velcro to the inside of your plane where the parts are marked “VELCRO”.
- The flight battery is also used to adjust your Center of Gravity as mentioned below.

Nosecone

RC_Instructions7.png 
Nosecone Assembly
- First lay down the parts pictured and insure they sit flat and snug.
- Now spread glue along all the joining edges.
- We recommend lightly hot gluing nose to fuselage so the nosecone can “pop off” in a crash and preserve this joint.
- Press the parts together firmly and pin and tape as need as the glue dries.

Leading Edge Flaps Airfoil
- Fit the missile rails into the notches and insure the pars are snug.
- Now spread glue along all the joining edges.
- Press the parts together firmly and pin and tape as need as the glue dries.

KF2 Airfoil
- For added speed, precision, and strength you can use a KF2 airfoil (step on the top of the wing).
- The KF4 (step on top and bottom) produces more speed and precision.
- Use Epoxy to attach the KF airfoils to the wings if you choose to use them.
- Use a KF at your own risk.
