Lark Model Aircraft
Print Profile(1)
Description
This drone features a classic 3D Printed configuration, equipped with a tail and pusher propeller, designed for optimal performance and a compact form factor. Its geometry has been rigorously validated through Computational Fluid Dynamics (CFD) simulations and actual flight tests. The platform design fully considers scalability and modularity: the nose is completely removable, adaptable to various cameras, sensors, and other payload equipment; the default configuration supports standard 19×19mm FPV cameras and a VTX lens built into the nose. All files are provided in STL format, with some also available in STEP format to facilitate easy editing and customization by users according to specific needs (such as camera mounts, antennas, etc.). When paired with the recommended motor system and a 21Ah 4S6P Li-ion battery pack, it can achieve low power consumption during stable flight, with an endurance exceeding 4 hours; with ample reserve power, it can still fly even when using only about 30% of its capacity, and can also be used with a 3S battery pack. Users can freely customize the payload and battery configurations according to their actual needs to create a personalized aircraft solution.
