The key objective with the ALTI Transition was to offer a highly capable, reliable and affordable civil use commercial VTOL (vertical take-off and land) aircraft, which one could actually purchase and use every day, unlike the majority of similar system, available only to military at high price points.

The Transition is made from the highest-grade materials, to the highest standards using unique proprietary techniques. An advanced aerodynamic design with low stall speed, efficient cruise with very low drag, excellent stability in high winds and an incredibly low weight at only 5.6kg for the entire airframe.

The airframe is completely modular and can be rapidly deployed, from in the case to in the air in under 10 minutes with only two operators required, this along with zero need for a runway or bulky and expensive catapult systems, provides quicker and safer operation, anywhere, any time. The Transition is designed as a hybrid system allowing for a combination of multirotor flight and traditional fixed wing flight, providing the advantages of both aircraft types, the practicality of multirotor flight for take-off and landing, with the efficiency, range and endurance of a fixed wing aircraft. The incorporation of VTOL technology into the fixed wing system allows the Transition to take-off and land in confined spaces, in a very short time, offering a massive advantage over traditional systems as well as a lower impact and stress on the aircraft with long term use, usually associated with hard and unpredictable parachute or belly landings.

The Transition’s airframe is designed by a South African Civil Aviation Authority approved Aeronautical Design Organisation, featuring a 3m dihedral wingspan, aerodynamic winglets and boom-mounted empennage, meticulously designed for efficiency. ALTI have developed various unique and proprietary features for the Transition, including but not limited to quick release wing latches, integrated internal fuel tank, aerofoil shaped landing gear, antennas build into the winglets and internal GPS, meaning zero drag induced by these systems. A rapid deploy airframe for quick assembly and transport, highly optimised manufacturing and composite techniques along with many other ‘ALTI only’ features not found on any other systems.

These features and design values allow for an incredibly low weight system with a maximum take-off weight of 16kg. The payload bay can be tailored and hot-swapped to fit and mount a wide range of cameras, sensors and other equipment. The system offers great flexibility without limiting the operator or mission scope. Designed to be aerodynamically stable and steady in low speed flight applications the ALTI Transition is designed to cruise at 20m/s. With a very low stall speed of 13m/s and and incredible endurance of 10+ hours.

The ALTI Transition is designed for civil and commercial use applications.

The ALTI Transition truly offers the next generation in unmanned aircraft technology, today.


The ALTI Reach is our upcoming 'bigger brother' to the Transition. Essentially a 6m wingspan scaled up version, it will be aesthetically and configurationally very similar to the Transition, offering vertical take-off and landing and efficient fixed wing flight performance. The Reach is currently in development and is planned to be in production and available for purchase later this year.

ALTI Reach Provisional Base Specifications:

Wingspan: 6m Base with 7m Optional Wing Extensions
MTOW: 65kg
Endurance: 20+ Hours
Max Payload: 8kg

As with the Transition, the Reach will be available in various options, airframe only, Base kits and fully complete ready to fly aircraft, offering the most advanced commercially available VTOL on the market in it's class. Please get in touch for further information on the ALTI Reach.

Advanced Airframe

Carbon composite materials

An incredibly efficient and advanced aerodynamic design featuring dihedral, washout and winglets, an integrated fuel tank built into the wing saving space, along with quick release connectors for assembly, all made from aerospace composite materials.

With a fully removable main wing section, adjustable avionics and payload trays, electric and fuel options, the Transition offers the ultimate in SUAS airframe technology.


Rapid Deploy

Setup and fly in under 10 minutes

A modular 'rapid deploy' airframe allows setup and flying within a few short minutes, no bulky and complex launch and recovery hardware is required.

The wings, and tail booms are easily and quickly removed without any tools, and the entire system packs into a compact case, ready for transport with massive cost savings and less hands required.


Ground Control Systems

Control, Data and Video

ALTI's advanced ground control systems offer everything from short range basic control to long range, vehicle mounted data telemetry, control, video links, payload control systems, tracking, as well as IP rated weatherproof hardware and flight cases.

ALTI runs UAVenture's AirRails GCS and software for the most advanced VTOL Autopilot system available.


Smart Design

Hardware + Software

We developed an advanced ALTI Autopilot specifically for the Transition VTOL aircraft, featuring high end components, GPS and sensors.

The ALTI Transition offers redundant flight control, with a split dual elevator, airspeed sensor along with our sophisticated code allowing for stall speed detection and many other fail safe features like weather veining, overbank protection, velocity checks and more, the multi-rotor will instantly take control when required.


Brushless Propulsion

Reliable Power

Operate with confidence, the ALTI Transition uses the best brushless motor technology available, with high performance carbon propellers and 80A motor controllers for smooth reliable thrust to get you airborne quickly and safely.

VTOL Propeller Size: 18"
Fuel Pusher Propeller Size: 14" Tri-blade


Navigation LEDs

Smarter and brighter

Ultra-bright, fully programmable navigation LED and strobe system, as well as a landing light underneath the airframe, with the ability to remotely turn the lighting on or off, as well as enable the landing light, special lighting features such as SOS, Morse and more.
