On Sunday, 5 April 2009 DRDO launched a test flight of the Nishant UAV. The main goal was to test the performance of the [[Wankel engine]] used on the UAV. An abandoned [[World War II]] runway at a village near Kolar played host to the first ever flight of this indigenous rotary engine-powered UAV. The flight took off on early Sunday morning and climbed to an altitude of {{convert|1.8|km|ft|abbr=on}} before cruising for a duration of 35 minutes. The air vehicle was recovered safely at the intended place at a dried-up lake, after a total flight duration of 40 min. The engine, a Wankel rotary type, was jointly designed and developed by [[National Aerospace Laboratories]] (NAL), [[Vehicle Research and Development Establishment]] (VRDE) and [[Aeronautical Development Establishment]] (ADE). The provisional flight clearance for the first indigenous prototype engine was given by the certifying agency, the Regional [[Centre for Military Airworthiness and Certification]]. The engine was cleared for flight after rigorous ground endurance test runs. The Wankel engine weighs about 30 kg (70 lb), and this engine type is known for its high power-to-weight ratio in a single rotor category.{{citation needed|date=June | On Sunday, 5 April 2009 DRDO launched a test flight of the Nishant UAV.

DRDO was satisfied with the test results. The performance of the engine during the flight met the requirements of the first flight of an engine in the air vehicle. This 55 hp indigenous engine is expected to replace the present imported engine of Nishant. The critical core engine, including the special cylinder [[Composite material|composite]] [[nickel]]–[[silicon carbide]] coating and special [[aluminium]] alloy castings, was designed and developed by NAL. VRDE developed engine peripherals such as the ignition and fuel systems and ADE developed flight testing. The reconnaissance UAV, which has completed its user trials with the [[Indian Army]], is expected to be handed over to the army shortly. | DRDO was satisfied with the test results.

A wheeled version of the Nishant UAV, named panchi, is under taxi trail as of September 2014, will be flight tested soon. UAV is capable of operating from semi-prepared runway, thereby reducing the turnaround time between missions, which is major advantage over the current catapult launched Nishant<ref name="The New Indian Express">{{cite web|url=http://www.newindianexpress.com/states/karnataka/UAV-Panchi-Warms-Up-for-Maiden-Flight/2014/09/18/article2437216.ece|title=UAV Panchi Warms Up for Maiden Flight|work=The New Indian Express}}</ref> | A wheeled version of the Nishant UAV, named panchi, is under taxi trail as of September 2014, will be flight tested soon.
