The MOLT MODELS design philosophy is comprised of methods that enhance scale appearance and all around flight performance. The first thing you’ll notice about a MOLT MODELS kit is that the majority of wood parts, illustrations and plans are CAD based.

MOLT MODELS Parkflyer F6F Hellcat Thank you for purchasing the MOLT MODELS Parkflyer F6F Hellcat. This kit represents a true first in parkflyer warbirds in that it possesses characteristics that make it both enjoyable to build and more importantly, fly. I sincerely hope that you enjoy your new MOLT MODELS kit. Please visit us at www.moltmodels.com for updates and information on future kits.

FUSELAGE BUILDING INSTRUCTIONS 1. Pin fs2 through fs4 on the plan sheet and glue adjacent edges together. 2. Glue formers (f1 through f9) to (fs2 through fs4) making sure they are perpendicular to the building surface. You also need to pay close attention to the orientation of all the formers.

5. Glue all 3/32" SQ balsa stringers to both fuselage side assemblies noting the end points of each stringer in Figure 2. 6. Glue the elevator pushrod exit ps to the fuselage side shown in Figure 2. When each fuselage half is removed from the building board they may warp ever so slightly, this is due to the stress the 3/32"...

8. Install the cockpit floor cp by gluing it to fs2a, f4, f5 and the 3/32" SQ balsa fuselage stringers. Refer to Figure 3 for cp's location. 9. Install the servo tray st by gluing it to f3/f3a and the 3/32" SQ balsa fuselage stringers. Refer to Figure 3 for st's location.

14. Install the elevator and rudder servos and GWS IPS as shown/described in Figure 4. Figure 4 Page 7 of 19...

15. Build the elevator and rudder pushrods as shown on the plan page. 16. Install the thin plywood control horns in the receiving slots in the rudder and elevator after these control surfaces have been covered. Note this is after the horizontal and vertical stabilizers have been built.

WING BUILDING INSTRUCTIONS Wing Center Section 1. Cut and pin the bottom 1/8"x1/4" balsa main spar, 1/8"x1/4" balsa servo mounting rails, 3/32" SQ balsa rear spar, wm2, and the 1/16"x1/4" balsa trailing edge stock to the wing plans on the plans sheet. Note the gap between the servo mounting rails was set per the dimensions of a Hitec HS-55 servo.

6. Glue wm3 to wm2, ribs R1, and trailing edge stock. The hole in wm3 is aligned to the hole in wm2 as shown in Figure 7. 7. Glue in the laser cut shear webs sw1 through sw5. Note that the grain of each shear web runs perpendicular to the building board.

Wing Tip Sections (follow steps 9 through 18 for both outer wing panels) 9. Cut and pin the bottom 1/16"x1/8" balsa tip spar, 3/32" SQ balsa bottom rear spar, g1, and the 1/16"x1/4" balsa trailing edge stock to the wing plans on the plan sheet. Study Figure 8 before proceeding.

15. Unpin each outer wing panel and "block up" each tip to the dihedral dimension shown in figure 9. At this point glue the outer wing panel spars to the center wing section spars as shown in Figure 9. Use a 90 deg triangle to make sure the outer panels are aligned over the plans.

19. The aileron servo installation is accomplished with the mounting screws provided by the servo manufacturer and left up to the builder’s preference. Fasten the servo to the 1/8" x 1/4" balsa servo mounting rails. I do not recommend the use of the rubber grommets that are included with the servo.

VERTICAL STABILIZER AND RUDDER BUILDING INSTRUCTIONS 1. Pin vs1 through vs10 on the plan sheet and glue adjacent edges together where applicable. 2. Next cut and glue each of the remaining 3/32” SQ balsa sticks to complete the plans. Note that each 3/32” SQ balsa stick is a square cut, a new straight razor will make short work of these.

WING MOUNTING INSTRUCTIONS 1. Mounting the wing to the fuselage on the Hellcat is pretty straight forward since the 1/8” wing-mounting dowel is positioned in the wing and the hole in the fuselage formers f3 and f3a receives the wing-mounting dowel. 2.

UNDER WING FILLER SECTION BUILDING INSTRUCTIONS 1. Fasten the wing to the fuselage. 2. Pin and glue the belly formers bf1 through bf4 on the bottom of the wing. The order of the belly formers is shown in Figure 12. Note the distances between the belly formers bf1/bf4 and fuselage formers f3/f3a/f6 shown in figure 12.

GENERAL FINISHING INSTRUCTIONS AND FLIGHT RECOMMENDATIONS 1. The battery is held inside the battery box with Velcro. Orient and glue the Velcro to the top and bottom of the battery box so that it will create a “belt” to keep the battery from coming out of the battery box in flight as shown in Figure 13.

2. Trial fit the horizontal and vertical stabilizers before covering. Perform any necessary sanding to achieve a good fit. 3. Cut out and fit the plastic canopy and cowling before painting and covering the fuselage. Perform any necessary sanding to the fuselage to achieve a good fit. The cowling slides over the front of the fuselage and should have a snug fit.

6. Cover and paint your model. I recommend Nelson Lite Film AKA Solite. These coverings can be purchased from www.toddsmodels.com . Scale paint schemes can be found on www.rcgroups.com and the World Wide Web. 7. Glue the control horns in the ailerons, elevator, and rudder. 8.
