Micro SSX Biplane
Flying weight: Approx. 6 - 7oz. (with recommended setup) Wing Span: 21 1/2" Wing Area: 240 sq. inches Wing Loading: 3.6 oz./ sq. ft. Length: 18”
The MicroSSX™ Biplane Build Kit is a fun-to-fly and build classic biplane version of the popular Millennium R/C MicroSSX airplane. The MicroSSX™ Biplane has the same wing span and length as the original Micro SSX™, and is similar in that it is aerobatic and can handle the wind fairly well, but the Biplane is capable of sustaining slower flight due to its lower wing loading.

Step by Step

The biplane has 8- 0.060” diameter carbon struts. 4 wing struts, 2 front and 2 center cross struts.
a. Wing struts: 4.840”
b. Front struts: 2.675”
c. Center cross struts: 5.000” (May need to be trimmed during installation)
To cut the carbon rods, use a sharp Exacto knife and a rolling action.
The cross struts are installed last.
Make sure they bottom out in the slots. Also make sure each set is exactly the same length. Do not install them until all warps are ironed out of the wings and told to do so in the instructions. Set them aside for now
Step 21 Tape a length of Scotch tape™ along the rear trailing edge of the horizontal stabilizer and secure with your finger (either side is fine). Now, flip the stabilizer and place on a work surface. See diagram below:
Step 22 Now, take the elevator. You will see that the elevator has a ‘beveled’ edge. This is important in creating the hinge. Ensure that the beveled edge is pointing up, and while holding at a 45° angle, place up against the trailing edge of the horizontal stabilizer and secure the hinge tape to the elevator with your finger. See diagrams below:
Step 23 Turn the stabilizer assembly over, and carefully fold the elevator back onto the stabilizer.
Step 24 Tape another length of Scotch tape™ along the bottom hinge line and secure with your finger.
Step 25 Fold the elevator back to normal position. Test the hinge by pulling gently on the control surface. Cut off any excess tape overhanging the stabilizer sides.
Step 26 Repeat the steps 21. thru 25. for the rudder and ailerons.
Step 27 Build the servo tray. Fig 20
Step 29 (Fig 21) Slide P12A onto the fuselage stick and glue 6-1/4” from the tail end. Slide P12 onto the fuselage and leave it loose. Slide the tail mount onto the fuselage end and align it so that it is square with the flat edge of P12A. Glue it and allow the glue to dry. Secure P12 to P12A with 2 #0-1/4 screw. Do not glue P12 to P12A. Slide the servo assembly onto the front of the fuselage, align it so that it is square with the flat edge of P12A and glue it with CA glue.
Step 30 Slide the fuselage assembly through the front lower wing mount. P12 should be glued into the slot on the trailing edge of the wing. Align the wing so that it is parallel to the tail mount. Glue the tail section vertical and horizontal stabilizer together so they are square. Glue the tail assembly to the tail mount. Make sure it is parallel with the wing. Fig 22, 23 and 24
Step 31. Slide the landing gear assembly onto the fuselage. Align it parallel to all other components. It should be 2-1/32” from the front end of the fuselage. Fig 25
Step 32. Install four 4.840” carbon wing struts. Make sure struts are fully inserted into the wing before gluing with thin CA. Fig 24
Step 33. Install two 2.675” front struts. Make sure struts are fully inserted before gluing with thin CA. Fig 25
Step 34. Install upper wing, making sure struts are fully inserted into the wing before gluing with thin CA. Also install the carbon cross struts. Fig 26
Step 35. Install battery mount. Fig 27
Step 36. Install motor mount. The kit includes mounts to accommodate different motor types. Fig. 27
Step 37. Install wheels, tail skid, control horns, pushrods and radio equipment.
Step 38. The model should be balanced at the CG 1.2” back from the top wing spar. Incidence must be adjusted to “0” using the adjustable rear wing saddle P12.
Control throws: Rudder Full deflection
Elevator 20 degrees
Ailerons 20 degrees
More extreme throws can be used as desired.
