Fei Bao EF 2000 Typhoon
Developed and written by Luke Cullen
The following instructions are developed based on a Kingtech K140 turbine,
Spektrum powerbox, and Spektrum and JR radio. Think of the build as working
from the back to the front which makes it seem easier. Every step focuses on easy
maintenance when the need arises.

  • Page 6: Air Systems

    FUEL SYSTEM: The EF2000 has a very simple fuel system, I have used a 1.9 litre tank above the ducting and 2 X 750 ml tanks on the engine rails. There is ample room for a UAT or similar header tank.
  • Page 7 Rudder: Rudder: Rudder: Rudder: The rudder servo mounts inside the fin and is secured by 4 screws. Rough up the rudder horns and check the depth where they sit on the rudder. Check the positioning as the hole in the horn should be directly over the hinge point.
  • Page 8 Rough up all the hinges with 60grit sandpaper before gluing them into the surface to ensure a good glue joint. You will also need to cut a slot in the side where the horn comes out for the linkage Mount the rudder on the fuselage with the screws already fitted inside the model as well as the 3mm bolt at the front of the rudder.
  • Page 9 Use an incidence meter to guide where you set the canards. Check the wings and then set the canards at the same angle. This will be very close for the test flight.
  • Page 10 Wings: Wings: Wings: Wings: The same methods are adopted for the servos and linkages for the elevons. Keep in mind the position of the control horns; they have to be directly over the hinge line. Make up extension leads for the elevon servos as they need to be longer. Hysol the horn in place after roughing the surface, you may need to increase the depth of the hole to get the correct position of the horn.
  • Page 11 Mount the servo to the plastic mounts provided and then screw the servo to the hatch with the countersunk 3mm screws. This is the leading edge slat one below but the same method is used on all the servos. Use Loctite on all screws to make sure nothing comes loose. Bolt on the linkages for the elevons and adjust them to suit the length needed.
  • Page 12 Mount the servos for the leading edge slats, I used Spektrum 6020 12 kg servos. Use the same method to mount the servos with the plastic mounts provided. I used heavy duty nylon servo arms and cut them off short. The room is limited in this area so trial fit everything.
  • Page 13 Where possible I used rubber grommets to protect the servo wiring. Enlarge the holes where the grommets sit for a good fit.
  • Page 14 Screw the covers provided to the wings to cover the servo arms and linkage. The end where the surface moves will need to be cut and made a separate piece.
  • Page 15 Sit the plastic cover on the wing to work out where to cut it. I screwed the pieces to the wing so if you needed access to the servo you could remove it easily. After the flying surfaces are finished I bolted all the rockets and tanks on with the hardware provided.
  • Page 16 Airlines: Airlines: Airlines: Airlines: Complete all airlines now so the ducting can be installed. It is also advisable to run all the extension leads for the rudders, elevons, leading edge slats, and nose wheel and canard servo. Black air hoses are for brakes; keep these identical lengths to keep your braking capacity equal.
  • Page 17 Ducting: Ducting: Ducting: Ducting: For simplicity I cut the front ducting so removing it was easier. You must fit the steering servo before all this is completed. The airlines and servo wiring needs to be completed before the ducting can be installed too. All hardware is included for the steering.
  • Page 18 Trim all the ducting to fit around the intakes and allow for easy maintenance if things need to be removed.
  • Page 19 T T T T ailpipes ailpipes ailpipes ailpipes Mount the nozzles to the fuselage with the 3mm bolts provided. Add the detail pieces to the rear and underside. The piece shown below mounts with a 3mm bolt too. I used Hysol to mount both pieces. This piece is glued with Hysol to the bottom of the fuselage between the exhausts.
  • Page 20 Use the 3mm bolts and washers to mount the exhaust nozzles. Test fit the exhaust pipe to check for length, this will determine where the turbine mounts. Ensure you mount the turbine as far forward as possible. Leave a 10- 15mm gap between the pipe and the outer nozzle that is fine.
  • Page 21 I cut a mount for the pipe from 6mm plywood. This mounts to the inner pipe and has relief holes to provide cooling between the pipes. This then mounts to the rear of the engine mount leaving the tailpipes 10mm inside the nozzles. The pipe setup aids with the cooling and performance of your turbine.
  • Page 22 Mount the pipe bracket to the engine rails with the bolt already there. I also mounted the bypass to the rails as well. This keeps the entire set up mounted solidly. Test fit the turbine and fit blind nuts under the rails. Also use the countersunk screws so they are flush.
  • Page 23 Mount the turbine using 4mm bolts, washers and loctite. When the turbine is mounted complete the wiring for the computer fuel lines and valves. When the ducting and wiring is complete clip up all wires where possible. The ducting will need trimming to suit your turbine. I made a relief cut under the round pipe for clearance on the fuel lines.

  • Page 24: Fuel System

    Fuel system: : : : Fuel system Fuel system Fuel system Plumb all the fuel tanks now so you can continue to move forward. I used Dubro tanks, one 1900ml and 2 x 750ml. Use Festo 4-6mm fittings for all the connections. They seal well and make it possible to do maintenance easily.
  • Page 25 Airtanks: Airtanks: Airtanks: Airtanks: I paired the 2 large tanks for retracts and doors. The 2 smaller ones operate the brakes. The 2 smaller tanks went on the underside of the tray and the large on the top.
  • Page 26 The EF2000 has a factory installed removable nose section which makes mounting the batteries very simple. I made a removable tray for both the batteries for the flight system. Mount the nosecone with the 4 x 3mm bolts using Loctite on them.
  • Page 27 I used an Airpower valve for the wheels, doors and wheel brakes. This makes for a neat installation because of its simplicity. After all the nose section and fuel tanks are finished the next step is to complete a tray for the starting gear and main fuel tank.
  • Page 28 The 2 piece detailed cockpit needs to be fitted so that removing it when the canopy to access all the batteries makes it more practical. This completes the build of the FB EF2000, go over the entire model before running the engine. Try taxi testing to adjust the sensitivity of the steering before...
  • Page 29 C/G 330mm from leading edge at the root of the left wing with the UAT’s full of fuel. Suggested engine sizes are 10-14 kilo thrust turbine. My model weighed 15.8 kilos dry when complete. Good luck and now enjoy this amazing model jet from Fei Bao.
