Project Overview
Project: Interactive Flying Dolphin Experience
Date: May 2026
Location: Rotterdam, Netherlands
Client: A European aquarium exhibition and family-entertainment operator
Application: Indoor seasonal exhibition and marine-themed visitor attraction
For its marine-life exhibition, the client wanted an overhead feature that could make the venue feel alive. The brief called for a realistic dolphin that could fly above visitors, hold attention across a large indoor space, and support scheduled live demonstrations without disrupting the guest experience.
HAFE supplied a customized Remote-Controlled Flying Dolphin with an upgraded model-aircraft flight-control system. The dolphin created a dynamic focal point above the exhibition area, combining lifelike movement, commercial-grade surface finishing, and stable indoor handling.

What the Client Cared About
The client needed more than an attractive inflatable. Their priorities were practical performance and long-term display value:
- Stable operation around HVAC airflow in a large indoor venue
- A realistic, premium visual finish suitable for public-facing exhibitions
- Easy daily operation, with a higher-specification option for live performances
- Flexible branding and customization, including color, size, print artwork, and logos
- Expandable show functions, such as lighting, tail movement, and bubbles
- Fast turnaround for a time-sensitive event launch
The HAFE Solution
HAFE proposed two configurations so the client could match the dolphin to its operating requirements and budget.
The elementary version provides straightforward remote-controlled flight. For professional performances, HAFE's model-aircraft flight-controller configuration adds gyro stabilization. This system helps the dolphin maintain a steadier attitude, hover more reliably, and respond more predictably when indoor air currents change.
Many entry-level flying inflatables use only throttle and directional controls. In venues with air-conditioning or changing airflow, these products can drift, become difficult to control, or collide with surrounding structures. HAFE's stabilized configuration is designed for applications where controlled, repeatable indoor flight matters.

Note: Advanced feature upgrades are available for the model-aircraft system. For illuminated designs, a white base film may be required to achieve the intended lighting effect.
Materials and Craftsmanship
The dolphin envelope is made from PP + PA aluminum film, selected for its low weight, strong air-tightness, and clean printable surface. Compared with ordinary PVC or standard nylon fabric, this material is lighter for helium-supported flight and can retain helium more effectively.
Its smooth surface also supports high-precision graphics, helping the product look polished in exhibitions, retail spaces, and branded event environments.
For repeat-use projects or more demanding environments, HAFE can offer specialty nylon or composite-coated materials with greater resistance to wear and UV aging. Depending on material selection, maintenance, and operating conditions, these upgraded options can support a service life of 3-5 years or longer.
Customer Feedback
“The dolphin changed the atmosphere of the exhibition immediately. It gave visitors something unexpected to follow and photograph overhead."
“The flight-controller version was noticeably easier to manage in the air-conditioned hall. Its movement looked smoother and more controlled during scheduled sessions."
“We appreciated being able to discuss visual details and functional options in the same customization process."

FAQ
Is the flying dolphin designed for indoor use?
Yes. It is intended primarily for indoor exhibitions, shopping malls, event halls, aquariums, themed venues, showrooms, and brand activations. The stabilized version is recommended for venues with noticeable HVAC airflow.
What is the difference between the two control systems?
The elementary version uses standard remote control for throttle and directional movement. The professional version uses a model-aircraft flight controller with gyro stabilization, providing more stable hovering and smoother control.
Which model supports special effects?
The professional model-aircraft configuration supports advanced upgrades, including light effects, tail-fin movement, bubble blowing, gold-powder effects, and stunt-flight functions. Final availability depends on the selected size and design.
Can HAFE add our logo or campaign artwork?
Yes. HAFE can customize the dolphin's size, color, pattern, logo placement, and printed graphics.
How long does helium remain in the dolphin?
Helium retention depends on the model size, material selection, temperature, storage conditions, and frequency of use. The PP + PA aluminum-film envelope is designed for better air-tightness than many conventional PVC or nylon-fabric alternatives.
Can HAFE develop more complex flying products?
Yes. HAFE supports multi-joint and multi-motor projects, including six-section snakes, T-Rex characters, reindeer with sleds, and large dragon airships. Such products require additional R&D, assembly, balance adjustment, and flight testing.
What is the usual production lead time?
For standard small-batch customization, lead time is generally 1-2 weeks. New structures, advanced effects, or multi-section designs may require additional development and testing time.
