Lynx M: 3 Hour Mapping Endurance


Greetings all. About a year ago, we introduced you to the Lynx. Lynx was our first system developed as an affordable, fixed-wing UAV for mapping. The Lynx design was inspired by military UAS, and we sought to make our own system that was equally durable and practical for field use.

Fast forward a year, and we are proud to announce the Lynx M. Our new design is approximately 20% lighter and 20% smaller than the original but with doubled endurance (3 hours with payload!), sideways camera placement (top facing forward), and more camera options.


Lynx M is an incredibly rugged, long endurance mapping UAS equipped with interchangeable sensors. The design is simple and assembly is quick, requiring no tools. A removable wing and tail simply slide into place on the fuselage and ‘shed’ on hard landings. Takeoff is accomplished with a hand launch, and landing is done with a vertical deep-stall or conventional belly land. The deep-stall enables users to operate from confined areas, such as a forest clearing.


  • Weight: 3.6 kg (8.0 lbs)
  • Wing Span: 2.3 m (7.5 ft)
  • Endurance: 3 hours
  • Propulsion: Electric
  • Construction: Kevlar, carbon, foam
  • Takeoff: Hand launch
  • Landing: Deep-stall or belly land
  • Payload: .7 kg (1.5 lbs)
  • Autopilot: Pixhawk


  • Tool-less assembly
  • Three piece wing & removable tail
  • Swappable payloads
  • Throttle safety key
  • Silent operation


The airframe is constructed to be as strong and as light as possible by utilizing a composite/foam core structure. A single airframe can withstand in excess of 100 vertical landings. Tests were conducted from a variety of terrain with camera onboard.  This makes Lynx M is one of the most rugged systems available.


Lynx M achieves three hour flight times with the standard 24 MP Sony a5100 APS-C payload. By combining long flight times with quality sensors, Lynx M can cover 8 square kilometers (almost 2,000 acres) at 2.3 cm/pix resolution. With the optional Sony a7R 36 MP full frame sensor, ground resolutions of 1.3 cm/pix are possible.

Payloads are located at the aircraft’s center of gravity and are thoroughly protected by removable foam mounts. Custom mounts can be made to carry additional sensors.



Autonomous takeoff, navigation, and mapping are done with the Pixhawk flight controller. SwiftTag post flight software is used to easily and accurately geo-tag and filter images based on aircraft position and attitude.

Lynx M packs down into two transport cases - one case for the aircraft and a second case for the battery charger kit.


Sample Flight Log

A Lynx M flight log can be found here:

  • Flight time: 186:57 minutes
  • Total distance traveled: 162.65 km
  • Payload: Sony a5100
  • Flight plan: survey grid & loiter

About Swift Radioplanes

Swift Radioplanes was founded in the summer of 2013 and based in mile-high Prescott, Arizona. The company designs and manufactures unmanned aircraft systems and performs photomapping services for research, simulator, agriculture, and survey applications. Swift Radioplanes emphasizes simplicity, durability, and performance in their aircraft. This design philosophy is easily seen with their flagship UAS, the Lynx M. Lynx is capable of three hour flights, a vertical landing method that requires incredible durability, tool-less assembly, and only three moving parts on the entire aircraft.

In December of 2013, a team from Swift Radioplanes volunteered to aid the Philippine disaster relief in the wake of Typhoon Haiyan. The team flew a Lynx UAS and collected and donated over 20 square kilometers of high resolution aerial imagery.

  • Same here...sent an email for a price quote... waiting for a response.
  • Hi Matt,

    We sent through a request for pricing/specs to your support email last week, awaiting response.



  • Hi, I want a quotation to my email please and more technical info. Great Job

  • Hi, I ask for a Quotation to your Email, I waiting your response.



  • @ rega

    Yes range can be extended with an optional radio. Please contact for pricing and specs. Thanks!

  • @Matthew, could you do further coverage? Like 10km

    Please advise on pricing.

  • @ Antonie

    Thanks! The weight depends on payload of course but its 3.2 - 3.8 kg. Max wind is 25 knots for good mapping results.

    @ Mark

    Yes, the Lynx designed was inspired by a few military UAVs. Please contact for complete pricing.

    @ Celal 

    Hmm... I did respond to your email. Sent you a PM just in case.

  • @Mattew, My question is in case of gimbal used, roll value from cam log can't tell the exact camera roll value. That's why I think you don't have to use cam log data in image processing.
