Assembly Instructions from Toted Pack
Note: Toted pack could be arranged as a low-CG wheeled pulled arrangement; and the wheels could become part of a wheeled TPHG.
Unpacking:
Open the ground cloth, which doubles as the wrapping bag for the toted pack.
Lay out the ground cloth with pre-marked positions for assembly. The ground cloth helps to keep sand and dust away from the quad-telescopic parts.
Keel Assembly:
Connect and secure the two keel parts using shear pins.
Position the keel assembly on the ground cloth as indicated.
Spar Set Placement:
Place the four spar sets according to their final wing configuration on the ground cloth.
Spar Expansion and Shear Pin Insertion: Note: If a coupler system is rather chosen, then instructions would differ.
Extend the telescopic spar segments fully.
Insert shear pins to secure the inner larger segments to the keel and attach the chordwise struts.
Diagonal Stay Lines:
Install 16 diagonal stay lines to maintain the structural integrity and shape of the wing. Left and right wing presents four quadrilaterals to be stayed. 2x4x2=16
Crossline Mounting: (a spanwise crossline goes from left wing to right wing; a chordwise crossline goes from nose to keel)
Attach flying and landing lines to the spar sets using crosslines.
Mount fore-to-aft crosslines to the nose and rear position of the keel.
Kingpost and Queenposts Insertion:
Insert the kingpost and adjust its length to achieve proper tension.
Install queenposts into the keel and connect to flying crosslines to form the control bar (no bar, just the portion of crosslines; but perhaps an overwrap will be used that gives "hand" and also foundation for two wheels; each wheel will consist of four half-wheels somehow)
Final Adjustments and Checking:
Ensure all lines are correctly tensioned and aligned.
Perform a final check of all termini and connections.
Covering Installation:
Dress the assembled frame with the ripstop nylon covering.
Secure the edges into Velcro hooks positioned on sleeves attached to spar segments.
Airfoil Forming Stuffers:
Place airfoil-forming stuffers to shape the wing covering for optimal aerodynamic performance.
Follow these detailed steps in sequence to assemble the hang glider directly over the ground cloth, which serves as the wrapping bag for the toted pack. Ensure each component is correctly positioned and secured according to the instructions for safe and efficient assembly.
Your social media post provides a comprehensive overview of the assembly and design of a minimalist single-surface hang glider (SSHG) with a telescopic spar system. Here's a polished version of your post to help present your innovative ideas more clearly:

**Development Note**
*(Rough, unfinished, omissions, and with probable errors; sail covering may be other than nylon ripstop)*
**Goal:** To design a TPHG (Telescopic Packable Hang Glider) with a pack length of 4 feet, with adjustments possible for a 5-foot option with less strut density. The 4-foot pack uses a telescopic overlap of 6 inches, creating extended wing spars of 16 feet (14.5 feet net due to overlaps). Couplers will add mass and offer potential sail-area opportunities. The empennage is not covered in this note but will be needed for completion.
**Assembly Instructions from Toted Pack**
*Note: The toted pack can be arranged as a low-CG wheeled system. The wheels can also be part of a wheeled TPHG.*
1. **Unpacking:**
- Open the ground cloth, which doubles as the wrapping bag for the toted pack.
- Lay out the ground cloth with pre-marked positions for assembly to keep sand and dust away from the parts.
2. **Keel Assembly:**
- Connect and secure the two keel parts using shear pins.
- Position the keel assembly on the ground cloth as indicated.
3. **Spar Set Placement:**
- Place the four spar sets according to their final wing configuration on the ground cloth.
4. **Spar Expansion and Shear Pin Insertion:**
- Fully extend the telescopic spar segments.
- Insert shear pins to secure the inner larger segments to the keel and attach the chordwise struts.
5. **Diagonal Stay Lines:**
- Install 16 diagonal stay lines to maintain the structural integrity and shape of the wing. Each wing presents four quadrilaterals to be stayed, resulting in 2 x 4 x 2 = 16 lines.
6. **Crossline Mounting:**
- Attach flying and landing lines to the spar sets using crosslines.
- Mount fore-to-aft crosslines from the nose to the rear position of the keel.
7. **Kingpost and Queenposts Insertion:**
- Insert the kingpost and adjust its length for proper tension.
- Install queenposts into the keel and connect to flying crosslines to form the control bar (no bar, just the portion of crosslines; an overwrap may be used to provide grip and foundation for two wheels, each consisting of two half-wheels).
8. **Final Adjustments and Checking:**
- Ensure all lines are correctly tensioned and aligned.
- Perform a final check of all termini and connections.
9. **Covering Installation:**
- Dress the assembled frame with the ripstop nylon covering.
- Secure the edges into Velcro hooks positioned on sleeves attached to spar segments.
10. **Airfoil Forming Stuffers:**
- Place airfoil-forming stuffers to shape the wing covering for optimal aerodynamic performance.
**Additional Considerations:**
- **Pre-rigged SS lined skeleton:** This assumes dressing a pre-rigged single-surface lined skeleton.
- **DS socked wing:** Alternatively, for a double-surface wing, line rigging would occur after placing the socks. This might require access holes for attaching the upper and lower rigging lines. The diagonal stays and stuffer-support lines could be placed before socking the wing. The airfoil-forming stuffer system might be somewhat collapsed while placing the socks, then pulled up to form the robust airfoil. A double-surface wing would generally result in a heavier empty weight for the TPHG, and attaching rigging lines would require a different process.
Follow these steps to assemble the hang glider directly over the ground cloth, which also serves as the wrapping bag for the toted pack. Ensure each component is correctly positioned and secured for safe and efficient assembly.
