PREPARATIONS ❏ 1. If you have not done so already, remove the major parts of the kit from the box and inspect for damage. If any parts are damaged or missing, contact Product Support at the address or telephone number listed in the “Kit Inspection” section on page 5. 1" [25mm] ❏ 2. Remove the tape and separate the ailerons from the wing and the elevators from the stab. Use a covering iron with a covering sock on high heat to tighten the covering if necessary.
❏ 6. To check that the joiners are properly installed, position the top wing upside-down on your flat building surface. The wing should lay flat. If it does not, remove the forward wing joiner, flip it over and reinstall it in the wing panels. Join the Top Wing Panels ❏❏ 1. Cut away the covering from the servo bay in the bottom of the right top wing panel. ❏ ❏ 2. A string is taped inside the servo bay.
Install the Bottom Wing ❏ 2. After the glue has cured, test fit the wing joiner into the bottom wing panels. Note that the wing joiner is angled to provide dihedral in the bottom wing. Also insert the smaller hardwood trailing edge wing joiner. ❏ 1. Cut the covering from over the two wing bolt mounting holes at the aft edge of the bottom wing. ❏ 3. To check that the joiners are properly installed, position the wing upright on your building surface. Place the included 1/2" x 1/2" x 3" [12.7mm x 12.
INSTALL THE STABILIZER AND FIN Install the Stabilizer and Elevator ❏ 1. Remove the two elevators from the stabilizer. ❏ 5. Measure the distance from the tip of the stabilizer to the center of the fuselage at the firewall. Adjust the position of the stabilizer until they are equal. ❏ 6. When satisfied with the fit, use 30-minute epoxy to glue the stabilizer to the fuselage. Double-check the stabilizer alignment while the epoxy is curing. Install the Fin and Rudder ❏ 1.
❏ 8. Trim the covering from over the slot at the lower leading edge of the rudder. Test fit the tail gear wire in the slot. ❏ 4. Use a canopy scissors or hobby knife to trim the plastic fin cover along the molded cut lines. Trial fit the cover over the fin. We found that cutting the front center from the cover allowed the fin to fit better. Trim the aft end of the cover so that it is flush with the trailing edge of the fin. ❏ 9.
INSTALL THE MAIN LANDING GEAR ❏ 11. Put epoxy in the tail gear wire hole in the leading edge of the rudder. Do not get epoxy in the slot. Before the epoxy cures, use thin CA to glue the CA hinges in the fin and rudder using the same method as before. ❏ 1. Attach the aluminum main landing gear to the fuselage with six #8 x 5/8" [15.9mm] sheet metal screws. The straight side edge of the main gear faces the front. ❏ 2. Glue the belly pan back in place with a few dabs of silicone glue.
INSTALL THE ENGINE Mount the Engine ❏ ❏ 5. Install a 4" [102mm] foam wheel on the axle followed by a 3/16" [4.8mm] wheel collar. Secure the wheel collar to the axle with a 6-32 set screw. Make sure to use thread lock on the set screw and tighten the set screw against the flat spot on the axle. ❏ 1. Use the template on page 35 to locate the four mounting holes for the engine mount. Align the marks on the template with the embossed lines on the firewall. Use a 7/32" [5.
❏ 2. Use four pieces of thin cardboard or plastic to mark the ❏ 5. Remove the cowl and position the engine on the mount location for the cowl mounting screws on the fuselage. The location should be 1/8" [3.2mm] from the front of the forward former, centered on the four plywood sticks. so the distance from the firewall to the front of the thrust washer measures 5-15/16" [151mm]. If the distance measured in the previous step was different than 5-7/8" [149mm], add 1/16" to 3/32" [1.6mm to 2.
❏ 2. Carefully bend one of the long tubes so that it will angle up toward the top of the fuel tank when inserted. Do not kink the tube. Mark a “P” on the outside of the front plate to designate pressure. ❏ 3. Install a piece of fuel tubing on each of the other two tubes. Attach a clunk on the ends of the tubes. Mark a “C” on the outside of the front plate by the short tube, designating carb. Mark an “F” by the remaining tube, designating fill. ❏ 7.
❏ 6. Connect the correct fuel line to the carberator and the fuel line plug to the fill line. The pressure line will be connected to the muffler once the cowl has been installed. ❏ 7. Use a #64 rubber band to secure the aft end of the fuel tank to the former. Install the Throttle Servo ❏ 1. Our test samples required some weight in the nose to balance at the forward CG. We recommend wrapping the receiver battery in foam and positioning it on top of the fuel tank.
❏ 7. Install a brass screw-lock pushrod connector on the throttle ❏ 9. Thread a nylon clevis 14 turns onto the 2-56 x 17" [432mm] metal pushrod. Slide a silicone clevis retainer over the clevis. Insert the pushrod in the outer pushrod tube and through the pushrod connector on the throttle servo. Attach the clevis to the throttle arm on the carburetor. servo arm. Secure it with a nylon keeper. Thread a 4-40 x 1/4" [6.4mm] socket head cap screw in the pushrod connector. ❏ 10.
Did you know? .... On July 10, 1931, the first order for 46 of the P-6E Hawks was placed. Of the 656 Hawks built, more than 1/3rd were exported to foreign countries. The lifespan in the U.S. Army Air Corp was short due to the development of the Boeing P-26A monoplane. ❏ 2. Use epoxy to glue the machine guns in the cowl. INSTALL THE RADIO SYSTEM ❏ 3. Trim the exhaust stacks as shown. We used black paint Install the Rudder and Elevator Servos to fill in between the stacks.
❏ 3. On the left side of the fuselage, slide one wire into the opening closest to the back of the fuselage. Install a large nylon control horn onto the clevis. Position the control horn on the rudder so that the clevis pin is in line with the hinge line. Mark the location for the screw holes. Drill through the marks you made with a 3/32" [2.4mm] drill bit, drilling only into the plywood plate. Do not drill through the rudder! Install and then remove four #4 x 1/2" [12.7mm] sheet metal screws.
C. Apply a small drop of solder flux to the joint. D. Heat the area to be soldered. Apply solder to the heated area. The metal must get hot enough to melt the solder and the solder must flow into the joint. Do not melt the solder by touching it to the soldering iron. E. Do not move the parts until the solder has cooled. F. Clean off the excess flux with alcohol. G. Test the joint by pulling on it. H. Apply a light coat of oil to the joint to prevent rust. ❏ 9.
plate in the aileron. Mark the location of the mounting holes onto the aileron. Drill a 1/16" [1.6mm] hole on the marks, drilling through the plywood plate but not through the top of the aileron. Insert and remove a #4 x 1/2" [12.7mm] sheet metal screw into each of the holes. Apply a couple drops of thin CA into the holes to harden the threads. Once the glue has cured attach the horn to the aileron with four #4 x 1/2" [12.7mm] sheet metal screws. Install the Aileron Servos and Pushrods ❏❏ 1.
INSTALL THE TOP WING ❏ 1. Attach the lower wing to the fuselage with the 1/4-20 nylon wing bolts. ❏ ❏ 2. Locate eight metal cabane mounting brackets. Set four brackets for the top wing to the side. We will be installing the brackets on the bottom wing first. Do the left wing first so your work matches the photos the first time through. ❏❏ 5. Note that the “N” strut has one leg that is slightly longer than the other. The shorter leg goes toward the leading edge of the wing.
❏ 10. Place the top wing onto the “N” struts. Attach the top wing to the “N” struts with 4-40 x 1/2" [13mm] socket head cap screws, #4 washers and 4-40 nylon lock nuts the same way you installed the strut to the lower brackets. FINISH THE FUSELAGE Build the Carrying Handle This kit comes with a convenient carrying handle for the fuselage and the struts. ❏ 11. Set the plane on its nose. Look at the relation of the top wing to the bottom wing. Be sure the top wing is parallel with bottom wing.
❏ ❏ 7. Place the two “N” struts into the handle. Put the handle top onto the part of the handle holding the struts and place the completed handle on top of the cabanes. Secure the handle to the cabanes with four 4-40 x 1" [25.4mm] socket head cap screws and #4 flat washers. This is how the completed handle looks when you are storing the parts or taking the plane to the field. 4. Glue the two parts shown onto one of the plywood carrying handle parts. Make sure the four holes are aligned. ❏ 5.
Assemble the Nose Weight Box Our prototype model required the addition of nose weight with engines at the bottom end of the recommended range. We have included a box for you to easily add the weight that most likely will be needed. ❏ 3. Fit the box cover to the box. Drill a 1/16" [1.6mm] hole at the locations shown. Install and then remove a #2 x 3/8" [9.5mm] sheet metal screw into each hole. Remove the cover, and then apply a couple of drops of thin CA into the holes in the box to harden the threads.
Optional Flying Wire Installation The photos on the box show optional flying wires installed on the plane. The materials we used for this are not included in the kit but are readily available at any fabric store for less than $10.00. The wires are made from an elastic cord typically used for sewing an elastic cuff in a sleeve. The material is commonly called, “Beading Cord Elastic.” You will need approximately seven yards, two small packages.
❏ 6. Continue threading the cord through the aft hole in the trailing edge of the stab on the opposite side of the fuselage and back down to the aft bottom of the fuselage. ❏ 7. At this point you will have to start stretching the elastic to complete the positioning of the elastic cord.You may need to trim a little off of the end of the cord to remove any slack before gluing it in the aft hole of the fuselage. ❏ 3.
❏ ❏ 11. Bring the elastic cord around the top of the forward ❏ ❏ 14. Bring the elastic cord around the top of the aft strut strut and pull it back toward the fuselage. Glue the cord into the hole next to the hole you started with. and pull it back toward the fuselage. Glue the cord into the hole next to the hole you started with. ❏ ❏ 12. On the side of the fuselage, 1-1/2" [38mm] from the leading edge of the bottom wing, make two marks 1/2" [13mm] apart, 1/4" [6.4mm] above the wing.
❏ 19. Cut four pieces of elastic cord 4-1/2" [114mm] long. Glue a cord into each of the four holes. Stretch the cord to the top of the cabane and glue the cord to the cabane with a small drop of CA. Apply the Decals ❏ 1. Use scissors or a sharp hobby knife to cut the decals from the sheet. ❏ 2. Be certain the model is clean and free from oily fingerprints and dust. Prepare a dishpan or small bucket with a mixture of liquid dish soap and warm water–about one teaspoon of soap per gallon of water.
IMPORTANT: The P-6E Hawk ARF has been extensively flown and tested to arrive at the throws at which it flies best. Flying your model at these throws will provide you with the greatest chance for successful first flights. If, after you have become accustomed to the way the P-6E Hawk ARF flies, you would like to change the throws to suit your taste, that is fine. However, too much control throw could make the model difficult to control, so remember, “more is not always better.
PREFLIGHT Identify Your Model No matter if you fly at an AMA sanctioned R/C club site or if you fly somewhere on your own, you should always have your name, address, telephone number and AMA number on or inside your model. It is required at all AMA R/C club flying sites and AMA sanctioned flying events. Fill out the identification tag on the decal sheet and place it on or inside your model. ❏ 1. Use a felt-tip pen or 1/8" [3mm] wide tape to accurately mark the C.G.
Balance the Propellers ENGINE SAFETY PRECAUTIONS Failure to follow these safety precautions may result in severe injury to yourself and others. • Keep all engine fuel in a safe place, away from high heat, sparks or flames, as fuel is very flammable. Do not smoke near the engine or fuel; and remember that engine exhaust gives off a great deal of deadly carbon monoxide. Therefore, do not run the engine in a closed room or garage. Carefully balance your propeller and spare propellers before you fly.
AMA SAFETY CODE (EXCERPTS) IMAA SAFETY CODE (EXCERPTS) Since the P-6E Hawk ARF qualifies as a “giant-scale” model and is therefore eligible to fly in IMAA events, we’ve included excerpts from the IMAA Safety Code. Read and abide by the following excerpts from the Academy of Model Aeronautics Safety Code. For the complete Safety Code refer to Model Aviation magazine, the AMA web site or the Code that came with your AMA license.
CHECK LIST FLYING ❏ 1. Fuelproof all areas exposed to fuel or exhaust residue ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ ❏ Fuel Mixture Adjustments such as the cowl mounting blocks, wing saddle area, etc. 2. Check the C.G. according to the measurements provided in the manual. 3. Be certain the battery and receiver are securely mounted in the fuse. Simply stuffing them into place with foam rubber is not sufficient. 4. Extend your receiver antenna and make sure it is in the antenna tube. 5.
come off the ground. One of the most important things to remember with a tail dragger is to always be ready to apply right rudder to counteract engine torque. Gain as much speed as your runway and flying site will practically allow before gently applying up elevator, lifting the model into the air. At this moment it is likely that you will need to apply more right rudder to counteract engine torque.
