Overview
A runway-free aircraft with fixed-wing range
The VF50P is a gasoline-electric VTOL fixed-wing UAV for missions where a multirotor runs out of time and a runway is not available. Four lift rotors handle vertical take-off and landing; the wing takes over in cruise.
At 55 kg maximum take-off weight, it carries up to 15 kg of mission equipment on a 3.8 m wing. Twelve litres of fuel give three hours at full payload and five hours at 10 kg.
The aircraft is built around long, linear work: corridor mapping, power-line and pipeline patrol, emergency observation and border or site patrol. A 30 km ground-station link keeps the operator clear of the work area, while a 1 km handheld link covers launch and recovery.

VTOL architecture
Lift vertically. Cruise on the wing.
The compound-wing layout combines four vertical-lift rotor units with a conventional fixed wing, so the aircraft launches from a small site and then flies like a wing-borne aircraft.
Four lift rotorsVertical take-off and landing
No runway, catapult or launch crew. The aircraft climbs and lands vertically from a compact prepared area.
3.8 m compound wingWing-borne cruise
In cruise the fixed wing carries the aircraft, which is where the long endurance and 150 km/h top speed come from.
Gasoline power12 L fuel
A gasoline engine provides hours rather than minutes of flight; refuelling between sorties is quicker than recharging battery packs.
Under-fuselage payload bayUp to 15 kg
Mission equipment is carried under the fuselage. Payload and endurance are traded directly: 15 kg gives 3 hours, 10 kg gives 5 hours.
Endurance
Three hours at full load. Five hours at ten kilos.
Published VF50P endurance figures, measured at sea level and 25 °C. Fuel capacity, not battery state, sets the length of the sortie.

Payload versus flight time
Plan for reserve fuel and return-to-base time. Actual endurance varies with altitude, temperature, wind and the installed payload.
12 L tank, refuel between sorties
Gasoline power removes the battery-recharge cycle from the mission day. The aircraft refuels on site and returns to work.
Flight envelope
Built for long lines and remote sites
The published envelope covers the conditions crews meet on survey, inspection and response tasks.
02
30 km command link
Ground-station control reaches 30 km in open, interference-free conditions; the handheld controller covers 1 km for launch and recovery.
03
12 m/s wind
Rated for 12 m/s wind, so exposed coastal, ridge and open-plain sites remain workable within the published limit.
04
3,000 m service ceiling
A 3,000 m ceiling supports highland survey and inspection; payload and fuel planning is required at altitude.
Applications
Where the VF50P goes to work
Six recurring missions where fixed-wing endurance beats a multirotor's hover time.
01
Survey and mapping
Corridor and block mapping, orthophoto and terrain data collection over areas too large for a multirotor sortie.
02
Power grid inspection
Tower, line and substation inspection along a corridor without taking the circuit out of service.
03
Oil and gas pipelines
Route patrol, valve-station inspection and leak-response support along long pipeline networks.
04
Emergency response
Airborne situation awareness and small-payload delivery during the first hours of a fire, flood or rescue task.
05
Police and border patrol
Persistent aerial observation for patrol, evidence collection and search work over wide areas.
06
Meteorology and environment
Upper-air sampling and environmental monitoring over remote or hazardous terrain.

FAQ
VF50P questions, answered
What payload can the VF50P carry?
Up to 15 kg under the fuselage. Endurance is published as 3 hours at the full 15 kg and 5 hours at 10 kg. The specific survey, inspection or cargo fit is confirmed with engineering during configuration.
Does it need a runway?
No. The VF50P uses four lift rotors for vertical take-off and landing, then transitions to wing-borne cruise. It can operate from a compact prepared site rather than a runway.
How is the aircraft powered?
A gasoline engine with a 12 L tank drives the fixed-wing cruise. The aircraft refuels on site between sorties; no battery pack swap or recharge cycle is required for the cruise phase.
What is the control range?
The ground station reaches 30 km in unobstructed, interference-free conditions. A handheld controller covers 1 km for take-off, landing and local manual control.
What wind and temperature can it handle?
The published envelope is 12 m/s wind, -10 °C to 45 °C and a 3,000 m service ceiling. Plan payload and fuel for high-altitude or high-temperature sites.
How long does a mission take?
With 10 kg on board the published endurance is 5 hours; at 15 kg it is 3 hours. Reserve fuel for transit, weather and return-to-base must be planned separately.
Can it be shipped and supported internationally?
Partdro supplies the aircraft, ground station and handheld controller with configuration and after-sales planning. Shipping, spares and training are quoted for the destination country.
What about approvals and local flight rules?
Approval depends on the jurisdiction. Partdro supports operators with documentation and configuration choices, but the operator remains responsible for permits and flight rules.

*** Endurance, speed and range figures are published manufacturer values; confirm the final configuration with Partdro before planning a mission.
1. Endurance figures are published for sea-level altitude and 25 °C ambient temperature: 3 hours at 15 kg payload and 5 hours at 10 kg payload. Fuel load, altitude, temperature, wind and payload change the result.
2. The 30 km ground-station range and 1 km handheld-controller range were measured in open, interference-free conditions. Observe return-to-base prompts and local radio regulations in operation.
3. The 3,000 m service ceiling and 12 m/s wind limit are published maxima. Reduce payload or fuel and plan alternative tasking when operating near those limits.
4. Payload integration, sensor selection and cargo fittings are confirmed per order. The airframe shown may carry different mission equipment from the delivered aircraft.
