* Skyblade II: Advance Production exploration, gasoline engine. Completely in-house developed. Didn't make it to full production.
* Skyblade III: Production version, all electric systems. Jointly developed with local research house (DSO National Laboratories)

The Skyblade III is designed for rapid 2-man deployment to support military and civilian applications. Developed for fully autonomous flight operations, it delivers quick and accurate intelligence in real-time to tactical commanders in the field.

* Skyblade IV: New tactical UAV

The SkyBlade IV is a completely new close-range tactical UAV unveiled in Asian Aerospace 2006, with a takeoff weight of 50 kilograms (110 pounds), including a 12 kilogram (26 pound) payload, a torpedo-like fuselage, a straight high-mounted wing with upturned wingtips, cruciform tailfins and a pusher prop driven by a piston engine with an endurance of up to 12 hours. The UAV carries an EO-IR sensor system with STA working on a miniaturized SAR. The vehicle is catapult launched and is recovered via parachutes or catch nets. Skyblade IV can perform a variety of operational missions such as surveillance, reconnaissance, fire support and battle damage assessment.
