Product Description

The 3-in-1 Foam Flying Shark Gliders are high-performance aerodynamic toys designed for outdoor play and physics-based learning. Constructed from EPP high-polymer material, these gliders are remarkably lightweight, flexible, and impact-resistant, allowing them to survive high-velocity landings without structural damage. The "3-in-1" designation refers to the adjustable tail-wing system, which allows the user to switch between different flight trajectories by simply changing the position of the horizontal stabilizer. Shaped with a sleek shark-inspired aesthetic, these gliders provide superior lift and a stable glide path, making them ideal for parks, beaches, and open fields.

Key Features

EPP High-Polymer Construction: Made from eco-friendly, non-toxic foam that is "memory-flexible"—it can bend significantly during a crash and snap back to its original aerodynamic shape.
Dual-Hole Tail Design: Features two slots for the rear wing; the bottom slot enables long-distance level gliding, while the top slot creates a "Loop-the-Loop" stunt flight path.
Shark-Fin Vertical Stabilizer: The unique shark-themed tail fin provides excellent directional stability, preventing the glider from "fishtailing" in light wind conditions.
Tool-Free Assembly: The wings and tail utilize a friction-fit "plug-in" system, making it easy to disassemble for transport or storage in a backpack.
Balanced Center of Gravity: Precision-weighted nose section ensures the glider maintains a proper "angle of attack," preventing stalls and maximizing airtime.

Technical Details

Weight: ~40 - 50 grams (Ultra-lightweight for extended thermals).
Impact Safety: The soft foam rounded nose minimizes the risk of injury or property damage during accidental collisions.
Weather Resistance: Water-resistant material that floats, allowing for safe recovery from ponds or pools.

Prototyping and Engineering Tips from Robogears

The "Launch Angle" Rule: For the longest glide, throw the plane parallel to the ground or slightly upward (approx. 10-15 degrees). Throwing it too steeply upward will cause a "stall" (the nose drops sharply), while throwing it downward will cut the flight short.
Adjusting for Wind: To achieve the best results, always throw the glider into the wind. The headwind provides extra lift under the wings, allowing the glider to climb higher and stay airborne longer.
Customizing Flight Path: If the glider consistently veers to the left or right, check for slight warps in the main wing. You can gently "bend" the trailing edge of the wing in the opposite direction (a technique called "trimming") to correct the flight path.
LED Modification: For night flying, you can easily tape a small 3V CR2032 coin cell and a 5mm LED to the nose. The EPP foam is translucent enough that the nose will glow, creating a spectacular "firefly" effect in the dark.
Structural Reinforcement: If you plan on using a high-powered slingshot or catapult to launch the glider, consider running a thin strip of fiberglass tape or a carbon fiber rod along the leading edge of the main wing to prevent the foam from flexing too much under high-G forces.

Package Includes

1 x Main Fuselage (Shark Body)
1 x Large Main Wing
1 x Small Tail Wing (Horizontal Stabilizer)

Disclaimer: This toy is designed for outdoor use in wide-open spaces. Avoid flying near power lines, busy roads, or rooftops. While EPP foam is highly durable, avoid stepped-on pressure which can crush the internal air cells of the foam. Not suitable for children under 3 years due to small parts if the foam is bitten or torn.
