Frequently
Asked Questions
The XT100 is a single-cylinder, liquid-cooled, two-stroke engine designed for compact UAV and aerospace-grade propulsion applications.
The engine uses a closed-loop liquid-cooling system that maintains stable operating temperatures under sustained high load, improving thermal efficiency and component longevity.
It incorporates a miniature electric starter, electronic ignition module, onboard battery, and compact exhaust assembly—reducing external systems and simplifying airframe integration.
The XT100 delivers a high power density relative to its mass, enabled by two-stroke scavenging efficiency and optimised port geometry.
Yes. The engine is engineered for reliable high-RPM operation with linear power delivery, supported by reinforced internals and efficient cooling.
It operates on a precision two-stroke fuel/oil blend. Mixture ratios are selected based on mission endurance, ambient conditions, and desired lubrication characteristics.
The XT100 utilises precision-balanced rotating components and optimised mounting points to minimise transmitted vibration and reduce structural fatigue on lightweight airframes.
The onboard miniature electric starter operates from the integrated battery, requiring no external power source for ignition or start cycles.
A compact, tuned exhaust unit is supplied as part of the engine assembly, providing stable back-pressure and reducing thermal footprint.
Maintenance intervals vary by operational profile; however, the simplified two-stroke architecture and integrated systems result in fewer service points and rapid field servicing.
The sealed system design protects key components from dust, moisture, and particulate ingestion, supporting deployment in austere or maritime conditions.
Yes. The ignition module provides straightforward electrical interfacing for telemetry, health monitoring, or platform-level FADEC/ECU integration requirements.
