  • Page 1 ParkJet Builder’s Manual Thank you for purchasing the ParkJet. The ParkJet is a profile ducted fan airplane that can be flown in a larger park. The ParkJet was initially designed by Scott Stoops and modified for laser kitting by Mountain Models.
  • Page 2: Required Equipment

    • There is very little that is critical when building the ParkJet. The only thing that requires special attention is to make sure the wings are not twisted. If the wings are straight, the ParkJet should fly hands-off without any trim.
  • Page 3: Wing Assembly

    • Heat shrink can be heated with a soldering iron or, if you dare, with a lighter. Pay close attention to what is near the heat shrink when you are heating it. • You really need the sealing iron (Also called a hobby iron). You will find putting on the covering so much easier.
  • Page 4 ! Position the upper and lower spar caps so that they line up with the notches in the ribs. Ensure that the end of the spar with the V shape is towards the center of the wing, that everything is tight, that the ribs fit fully into the spars and that the vertical spar is touching the cap spars.
  • Page 5 ! Lightly sand the wing to remove any bumps and glue Covering the Wing The ParkJet kit comes with a clear, paintable covering called Doculam which is actually a laminating film. The frosted side has a heat activated adhesive. Unlike most coverings, Doculam does not have a backing sheet.
  • Page 6: Fuselage Assembly

    ! You can paint the supplied Doculam covering with Testors Pactra Racing Finish car body paint, which has been specifically designed for lexan car bodies. Krylon spray paint will also work. Fuselage Assembly ! Lay the 3/32” balsa fuselage on a flat surface. ! Lightly spread white glue completely over one side of the fuselage and position one of the 1/64”...
  • Page 7: Final Assembly

    ! Glue the 1/16” plywood battery mount to the bottom of the battery opening. Attach some Velcro to the mount. Final Assembly ! Carefully measure the exact center of the wing and remove a 3/32” strip of covering from the center section of the wing.
  • Page 8 ! Glue the long control horn into the elevator. The elevator horn faces down. ! Glue the two aileron control horns to the ailerons, facing down. ! Install the servo control horns on the servos. The aileron servo needs a double sided horn and the elevator servo needs a single horn.
  • Page 9 (the middle of each wing) and lift the ParkJet. It should balance there. If not, adjust the battery forward or backwards till the CG is correct.
