Page 3: Mounting Of Main Gear
+++ construction manual SR 71 Blackbird (EDF Version) from JetCom +++ Mounting of main gear The landing gear compartment frames are already laminated. The centre of the retract plate is located as shown in the picture below. The cut-outs need to be 46 mm x 36 mm and be made on the bottom of each wing half.
Page 4: Mounting Of Nose Gear
+++ construction manual SR 71 Blackbird (EDF Version) from JetCom +++ Install the retracts and the struts. Mark the cut-out for the struts on the bottom of the wing and the fuselage. Cut the wing skin to allow the struts to retract properly in and out making sure you have enough clearance.

+++ construction manual SR 71 Blackbird (EDF Version) from JetCom +++ Afterwards fit the retract plate into the U-shaped milling of the compartment frame. Please make sure the retract runs parallel with the fuselage to allow the strut to retract properly in and out.
Page 6: Installation Of The Rudders
+++ construction manual SR 71 Blackbird (EDF Version) from JetCom +++ Installation of the rudders The functional installation of the rudder does not support the flight qualities. However, to follow specific requirements the rudders can be installed functional as follows: You need to cut the rudder as shown in the pictures below.
Page 7 +++ construction manual SR 71 Blackbird (EDF Version) from JetCom +++ The rudder servo is located in the rudder. A servo mounting plate and a servo covering fitting for a Hitec HS 125 MG or equivalent is provided in the kit. Using a razor saw, cut the skin of the rudder to accommodate the servo and the servo tray.

+++ construction manual SR 71 Blackbird (EDF Version) from JetCom +++ Afterwards roughen the installation face of the rudder and on the fuselage carefully. Now you can glue the rudder onto the fuselage. Eventually bulging out epoxy should be removed immediately. For a smooth transition you can flatten the gap with smoothing cement.
Page 10: Installation Of The Edf
+++ construction manual SR 71 Blackbird (EDF Version) from JetCom +++ After connecting the elevons with the servos, you should adjust the deflection (see page 19 of the manual). Last but not least the servo covering should be fixed. Please pay attention that the servos keep functional afterwards.
Page 11 +++ construction manual SR 71 Blackbird (EDF Version) from JetCom +++ After you have prepared all air intakes as described, you can go ahead assembling the tubes and the EDFs as demonstrated on the following pictures: The tubes will be affixed on the EDF by using adhesive tape that is wrapped around the EDF and the pipe coupling.
Page 12 +++ construction manual SR 71 Blackbird (EDF Version) from JetCom +++ Now you can implement the EDF units in the gondolas. This should be done from the back of the model. When doing so, please pay attention not to deviate the cables.
Page 13 +++ construction manual SR 71 Blackbird (EDF Version) from JetCom +++ At the outlet the tubes can be fixed with a 1 mm balsa layer. If necessary add a plywood layer in addition. After fixing the tubes in the gondolas like this glue it with Hysol or equivalent.
Page 14: Installation Of The Battery
+++ construction manual SR 71 Blackbird (EDF Version) from JetCom +++ Installation of the battery The battery must be placed in the center of gravity (see page 19 of the manual). Ensure that they are not able to move during the flight (e.g. by fixing them with ...
Page 15: Suggestion For The Installation Of The Interior Equipment
+++ construction manual SR 71 Blackbird (EDF Version) from JetCom +++ Suggestion for the installation of the interior equipment It is always a matter of individual preference on where to install the various electronic components, receiver, battery and so on. The pictures below show the installation we have used for our model.
