Thank you for purchasing F9F-6 Cougar from www.Rbckits.com
For the first time, R/C enthusiasts we have a choice in scale and fun flyer aircraft designs.
Our goal, through computer technology and state-of-the-art production techniques, is to offer aircraft
which in the past have not been modelled simply because they weren't popular enough to justify mass
production. Our production techniques allow us to produce aircraft which, though not as popular and
well known as P-51s and P-47s, still offer historical significance (good or bad!), Good looks and flying
characteristics, and a uniqueness that is sure to turn heads wherever you take your airplane!
Your airplane has many unique features in its design:
CAD Design
CAD design allows strength to be built into the airplane without sacrificing weight. Accurate parts
design and placement ensures a perfect fit.
CAD Drawn Plans
The plans in this kit are not copied from a master set! They are originals drawn directly from the CAD
program where the airplane was designed. We do this because it allows us to use colour, which helps
you better visualize the various components of the airplane, and we can use better quality paper,
which greatly reduces the possibility of shrinkage.
Since you're going to build directly on the plans, they ought to be the proper size! Also, parts
placement is guaranteed to be accurate, so you can build a better, straighter model.
Small and hard-to-produce parts are simply a computer file away, so you get a more accurate airplane.
Lightening Holes
Lightening holes are cut into all ribs and formers where possible and justified. This allows us to keep
the weight on each plane to a minimum without sacrificing strength.
The same program that generates the design and plans also drives the cnc cutter, so every part is
reproduced exactly as it was designed. cnc cutting also allows us to fit more parts on each sheet of

  • Page 2 PETG General Building Information The F9F-6 Cougar can be built by a person with building skills. It is designed for someone who has built a low wing warbird. No unusual building techniques are required, although more difficult areas are explained in detail where necessary. Certain steps in the building process must be followed as depicted, or you might find yourself digging back into the structure to redo something.
  • Page 3 All vacuumformings should be roughened up before gluing Check the 3d pdf (you need adobe x10) and pictures for additional information, a picture says more as a 1000 words so do look at the pictures on the cd Note that there is a extra directory with pictures of the build with the fan forward, the build does not differes from this Wings: Start with a flat building board with the size for the wing and fuselage...
  • Page 4 Join main formers and place rib doublers , check the drawing for the correct position of the doublers and or retract formers. Mark the main-formers ribs on the bottom sheeting, place main-formers on sheeting place ribs , do not glue yet , make sure for straightness . if all seems ok then pin down the main former and start glueing the ribs with thin ca one by one to the bottom sheeting, note roll the ribs over the sheeting and apply ca Glue wing assembly to bottom sheeting.place scrap fills, aileron leading edges...
  • Page 5 Make the top sheeting from the supplied balsa , place also some scrap balsa for hinges and horns Place servo and wires into the wing , place servos on extra 1,5mm balsa , we shrinked the servo in shrinking foil and ca them to the bottom sheeting, with a fill on top, make also a opening for the servo arm in the bottom sheeting.cut the top sheeting as per plan.
  • Page 6 Clean up the edges of the wing and place leading edge sand leading edge to shape as per plan , place wing-tips and take out ailerons and sand edges as per plan. Place wing tips and sand to shape Make the ailerons with the cnccut parts and do place them in the wing with the hinges (do not glue)and sand tot the shape of the wing and wing tips, after that shape the leading edge of the aileron to form...
  • Page 7 use the supplied hinges for the ailerons they are easy and do perform very well, but do pin them with needles and ca Placet he wing tot he fuselage with the supplied spruce wing joiners, use slow glue, you can do a bit of alligning here Choose your retracts and open up the bottom sheeting for taking the retracts and wheels .use the drawing as reference, you can use the cutout of the wing for retract doors, also the small opening,...
  • Page 8 place hinges, place servo arms and make opening in aileron for the horns, center servo and aileron and glue in horns we used very secure Z-Bends Fuselage : Join formers as per drawing , join main crutch and pin down on a straight building board, place a straight construction line on the board.
  • Page 9 place formers as per drawing, make sure for straightness , it is easy if you sharpen up the little tabs a bit , it will slide in easyer in the openings Construct front part of fuselage , no glue used yet. Line out fuselage assembly with some small blocks of wood Note that the position of the edf unit is 1 former more forward as in this pictures...
  • Page 10 Line out assembly on the workplate make sure both sides are level before glueing better support both main ribs with blocks from equal size If you are sure now you can use ca to fasten all formers...
  • Page 11 Place intake tube sheeting from the back of the fuselage Cut paper intake as per plan make oversize on fan side and intake side Use ca to fasten paper duct and cut duct to size...
  • Page 12 Place 3x6 duct strenghteners for preventing to collapse the duct Place intake sheet fills to paper and former F7A, place 3x6 stringers Cut the fairing sheet oversize a bit and cut fit to the frame Place top fairing also...
  • Page 13 Sand edges , the trailing edge of the fairing to the Former F16 Make up rudder from formers as per plan Join formers...
  • Page 14 Start sheeting rudder with the 1,5mmx50 sheet make cuts in the sheet as per plan the concave formers make sheeting a bit difficult , use water to soften balsa. Make opening for Stabilizer also.Place fairings do test foit the stabilizer Make opening for elevator servo,and glue in servo...
  • Page 15 Make opening for servo steering arm and wires as per plan The stabilizer is joined in the rudder Use a wire to measure the alignment of the stabilizer to the fuselage Before this we have to sheet the fuselage with the 2,5x12x1000 (24pcs) strip balsa Start in the center and work your way to the top The hatch cutout should be made soon as it is likely to have it glued to the forms so carefully use glue there and cut out hatch asap, note that the hatch shown here is not in the kit , the kit has a larger...
  • Page 16 Sand intake side to take the sheeting Sand edge of MC4 to take the sheeting...
  • Page 17 Sand complete fuselage assembly Make nose cone place former after scribing of a line parallel to the bottom of the nose cone for correct alignment to the fuselage...
  • Page 18 Cut locating dowel in 2 small pieces Place to fuselage and sand to shape Canopy frame: Make frame from formers as per plan , cut two small corner pieces to glue in the front corners.
  • Page 19 Do test fit the frame , the canopy should fit over the frame and flush with the fuselage sand for good fit. Place cockpit parts and canopy closing Front retract, your choice but we have used a HK part the retract door closing is a difficult part on the drawing is a better solutionwe think.
  • Page 20 Outlet duct: Cut from supplied pvc sheet as per plan, tape the duct sheet on the lines and it should fit to the fan unit and into the fuselage. Use a small piece of tape to fasten the tube to the fan unit Place vacuumformed fairings to fuselage wing , sand to flush fit Place flow separation plate to wing as per plan...
  • Page 21 Finishing: The whole airframe is covered in 25gr glass and doped with filler dope, DO NOT USE SHRINKING DOPE EVER. Filler dope is not too hard to sand, and filled with some extra talcum powder sands great and smooth, when ready a thinned layer of sanding dope is OK Now finish with...
  • Page 22 If you need additional pictures, just ask. Have Fun with the F9F-6 Cougar Additional HQ pictures are on the disk , also a 3d pdf , where you can see all parts of the Cougar in 3d , you need adobe 10X to view, it will not work in your browser WWW.RBCKITS.COM...
