Q4T Drone
Q4T Drone - Overview

The Q4T drone is the evolution of our Q4E. This new UAV designed by Mavtech features higher payload and flight time, better structural design with just 5% increased wheelbase compared to Q4E. The autopilot is still Pixhawk 2 which is a powerful and reliable flight controller, that gives the widest configuration options and the most advanced controls for stand-alone flying and piloting assistance (optionally, it is possible to install the GPS RTK navigation system). The propulsion system is T-Motor based. The battery is housed inside a sliding case that is inserted into the center of the main frame. In this way the UAV balance is always optimal and the layout is clean and drag-effective. This solution allows to mount any 6s battery that meets the minimum continuous discharge requirement of 1300 W. The battery connector incorporates a spark protection circuit for maximum safety and longevity.

The Q4T drone is the ideal flying platform for photogrammetry, for search and rescue operations, surveillance operations and in general in all those professional applications that require a precise and reliable navigation system. It is also a proper flying platform for research and development purposes, where it is mandatory to easily access and re-configure the autopilot. Q4T drone is the ideal solution for those who need to develop unconventional navigation systems based on pixhawk / px4, providing a stable, ready-to-fly aerial platform.

In short, the key features of the Q4T drone are:

  •     Simple and modular structure
  •     Flexible configuration
  •     Great availability of accessories
  •     Tool-free quick-release landing gear
  •     Tool-free quick-release carbon propellers

Q4T Drone - Sensors

The Q4T drone is capable to carry on board a widespread of sensors, thanks to its high flexibility. The endurance of the aircraft should be evaluated on a case-by-case basis, according to the Payload / Batteries ratio. We provide feasible flight time for each configuration, but only if recommended batteries are used. Some sensors have already been tested during the development of the Q4T, for which nadiral installation kits are already available, for example:

Other sensors that can be installed in the nadiral position are:

For other sensors or non-nadir installations (i. e. on gimbals), custom or COTS solutions will be evaluated, depending on the specific application.

Single Case Solution Available

The Q4E drone can be folded in our rugged custom cases. You can choose between a case that includes Q4E, all accessories and radiocontroller or a smaller one, to inlcude only the Q4E drone with accessories. All our cases are waterpoof and suitable for transportation: the internal foam ensures maximum equipment protection. Choosing smaller cases leads to easier transportation: two cases can be ordered, one for the Q4E and one for the radiocontroller.
