Fast, long range and small, the UltraManx is a improved version of the Super SkyManx redesigned to be simpler to construct. The UltraManx is meant as a complement to similar planes like the Turbo SkyGnat and StarSerpent.
The UltraManx's development was a straightforward modernization of the Super SkyManx design. The conventional design accepted the redesigned tail configuration (common to the SkyStinger and other designs) and construction of the prototype came along quickly. Flight testing proved the new design capable and it was approved for publication shortly thereafter.
TAA USAF Designation: D409-1
Step 1: Materials
1 Piece of 8 by 10.5 inch graph paper (4 boxes per inch)
Step 2: Begin Construction
First, begin by folding your your graph paper in half (excluding three boxes on the perforated side). Once the paper has been folded appropriately, make two marks--13 full boxes apart. Use a ruler to make a straight line with the length of 13 boxes directly up 1 row of boxes from the two marks you just made. Then make the rudder and counterweight as shown. Follow the photograph markings. Then, mark out the wing spars and skids. Half a box forward of the trailing edge of the vertical stabilizer, make a solid horizontal line 2 boxes in length as shown (this will later become the slot through which the horizontal stabilizers pass). Also, draw the diagonal line along the bottom of the fuselage.
After the fuselage is made, take another sheet of paper that is folded
in half along the lines of boxes. Mark out the wing as shown (2 boxes in length by 4 boxes in width, and a swept portion in front of this box of 1 box eliminated every 4 boxes away from the fuselage). Half of a box in from the wingtip, make a dotted line parallel to the wingtip. Measure 2 boxes along the crease, measure two boxes upwards from one side and the one box forward. Then draw a diagonal line connecting this line the other edge of the line along the crease. Then cut it out.
Solid lines indicate places to cut. Dotted lines indicate fold lines.
Note: 1 box = 0.25 inches
Step 3: Making the Fuselage
Cut out your fuselage and fold the counterweight into itself as shown.
Then unfold the fuselage and cut the right vertical stabilizer off. Then restore the fold. Fold the fuselage forward at the vertical dotted line on the vertical stabilizer. Once you have made the cut along the solid line, unfold. Once this is done, fold down the spars and skids. Then apply tape where designated. Now cut along the diagonal line at the keel of the airframe.
Step 4: Applying the Wings and Horizontal Stabilizers; Stapling
Cut out your wings and lay them out flat. Align the fuselage over top so the spars align with the wing as shown. Then apply tape. Cut off any excess. Flip the aircraft over and apply tape to the leading edge of the wing above the leading edge root extensions.
Once you have finished with the wings, cut out your horizontal stabilizers and slide them through the slit in the fuselage you made earlier. When through, fold them up and apply tape to the underside; then fold down.
Then apply one staple in the area of the counterweight. This will have completed your aircraft.
Step 5: Flight
The UltraManx flies very similar to Super SkyManx and is quite docile. Launches at moderate speed at a neutral attitude will result in best performance. Trim may be necessary, so test flights are recommended. Additional applicable surfaces include slats, ailerons, flaps, flaperons, elevators, a trimmable rudder and air brakes. Enjoy!
