The Ideal Development Framework
H.E.L.I.O.S is more than a template. It is a complete prototyping environment for drone-based systems.
Developers can rapidly iterate on flight behavior, camera motion, control logic, and environmental interaction without rebuilding core systems. Whether you are validating a concept, building a cinematic tool, or developing a simulation-heavy project, H.E.L.I.O.S dramatically shortens iteration time while maintaining technical depth.
A Blueprint Masterpiece
H.E.L.I.O.S is built entirely using Unreal Engine Blueprints, demonstrating advanced Blueprint architecture at production scale.
- Highly Modular: Tweak parameters effortlessly without delving deep into the code. Freedom to create and adapt is at your fingertips.
- Cleanly Structured & Documented: Blueprints are logically organized and thoroughly commented to support learning, customization, and long-term maintenance.
Designed for Versatility
H.E.L.I.O.S adapts seamlessly across multiple domains:
- Game development
- Cinematic and virtual production
- Simulation and prototyping
- Technical experimentation and research
The system is designed to scale from lightweight gameplay scenarios to physically demanding simulation environments.
In-Depth Flight Modes
Each flight mode is designed to reflect authentic multirotor behavior while remaining intuitive to use:
- Air Mode: Ideal for those looking for dynamic flight control. It ensures the drone maintains some level of control and maneuverability even in freefall, ideal for performing stunts and enhancing overall flight dynamics.
- Velocity Mode (Position Hold): Ideal for beginners, Velocity Mode helps the drone maintain its position against wind by simplifying control to direct drone’s movement in any direction based on pilot inputs. It’s the most user-friendly mode, focusing on stability and ease of use.
- Angle Mode: Offers control over the drone’s tilt, providing a balanced mix of maneuverability and stability. It’s suited for pilots who want to navigate through various angles with ease but still maintain a degree of control.
- Acro Mode: Acro Mode is all about giving pilots complete freedom over the drone’s orientation for performing complex maneuvers and aerobatics. This mode is for experienced users looking for a challenging and unrestricted flight experience.
- Cine Mode: Designed for video production, Cine Mode smoothens flight controls and stabilizes the camera to reduce sudden or abrupt movements. This mode is aimed at capturing smooth and stable footage.
Included Drones
H.E.L.I.O.S ships with two fully configurable quadcopters:
- Atlas: A cinematic-focused drone designed for stability, smooth motion, and controlled flight.
- Icarus: An FPV-oriented drone tuned for agility, responsiveness, and aggressive maneuvering.
Each drone serves as both a ready-to-use asset and a reference implementation for customization.
Aerodynamic & Environmental Simulation
H.E.L.I.O.S includes multiple air resistance models to support different development needs:
- Simplified Model: Designed for computational efficiency without sacrificing quality, this model provides a robust simulation of air resistance and wind gusts. It’s an excellent choice for users who need a balance between performance and realism.
- Advanced Model (Beta Stage): This model goes beyond basic drag simulation by incorporating turbulence and the ability to simulate torque effects due to pressure changes, providing a more realistic depiction of fluid dynamics. It’s designed for users who seek to explore the full spectrum of aerial dynamics and fluid behavior, currently available in its beta phase for those looking to experiment with advanced simulations.
Integrated Systems & Tooling
Every aspect of H.E.L.I.O.S has been designed with user convenience in mind.
- Cascaded PID Control System: A multi-layer control architecture enabling precise, stable flight across all modes.
- Dynamic Sound Design: Adaptive sound effects respond to motion, speed, and environment.
- Ready-to-Use UI & Menus: Fully functional HUD, settings, and pause systems designed for immediate integration.
- Extensive Parameterization: Flight behavior, physics response, and control feel can be tuned without restructuring the framework.
Documentation & Long-Term Support
H.E.L.I.O.S includes structured documentation and a growing set of guides to support onboarding, upgrades, and customization. Manual upgrade workflows are provided to ensure existing projects remain compatible as the system evolves.
Community feedback plays a key role in shaping future improvements.
The Meaning Behind the Name
Inspired by Helios, the Greek god of the Sun and vision, H.E.L.I.O.S represents clarity, control, and perspective. The framework is designed to illuminate new creative and technical possibilities within Unreal Engine.
