Although we produce some standard aircraft, it is often the case that a particular application needs something slightly different. There is often a need to find a machine that can operate within quite specific operational parameters, in unusual ways or very particular circumstances and, with the number of ways these aircraft might be used increasing constantly, this is far from uncommon. Currently the vast majority of our work involves some kind of system customisation. This may be something as simple as specifying a particular set of components to optimise performance, but can often involve more. Making changes to an airframe to enable the use of different sensors, fit unusual antennas, attach non-standard payloads, integrate power systems for payloads, customise landing gear, or customised functionality are commonplace. In some cases an entirely bespoke aircraft specifically designed for the particular application may be the only solution.
With our long history of building unusual VTOL flying machines, and our ability to manufacture many parts either in house or through our carefully chosen manufacturing partners, we are able to work with our customers to produce bespoke or customised systems that most closely fulfil their specific requirements. Please feel free to get in touch if you would like to discuss your project, we are happy to sign an NDA if required and you may be surprised how inexpensive a custom solution could be.
D8 High Altitude Spraying
This D8 series aircraft has been produced to allow spraying at much greater height than the original Harrier version. The D8 is a very powerful aircraft that can lift the hose full of water to over 200 feet. Spraying is undertaken using our 2nd generation robotic spray arm that now offers various control modes such as full proportional, position and hybrid position modes, and also includes automated side to side and rotational movements of the spray arm to cover specific areas with only general directional control required from the operator. A clear view of the spraying operation is provided by a high mounted FPV camera including a one axis gimbal with a cleaning pad to keep the camera free of water and maintain a clear view for the operator.
Industrial Jet Wash – Harrier 7
This waterproof Harrier 7 variant is fitted with a high power jet wash with custom built remotely operated robotic arm. Designed to operate at up to 20m above take off point (to cover tidal variation) this aircraft is used to clean the guano from access landers on the new breed of ultra large wind turbines in the North Sea. Located over 100 miles off shore, these turbines provide the only place to land for sea birds for miles and so attract them in huge numbers. The resulting guano presents a significant health and safety risk to engineers working on the structures and has to be removed prior to access. Operating from a crew vessel in what can only be described as very harsh conditions this aircraft is highly resistant to wind, rain and spray, and with it’s high pressure cleaning payload enables safe access without risk to engineers who would otherwise have to call in a specialist crew to clean the structure.
BioCarbon Engineering V3
Having gone commercial at the end of 2017 Biocarbon Engineering go from strength to strength with a rapidly expanding fleet of the version 3 tree planting aircraft. This version is white to help with heat management in hot climates and features a laser altimeter and RTK GPS for precision low level autonomous mission flying and precise positioning of each tree that is planted. The current system is capable of planting an incredible 600 trees in 10 minutes!
With three years of R & D behind them and fully verified success rates across a wide range of species, BioCarbon are well on their way to their target of planting a billion trees a year!
This world first from Flying Screens (a joint venture between RES Ltd. & Light Initiative Ltd) presented us with some unique challenges! Each aircraft carries a pair of ultra bright hi resolution LED panels displaying live co-ordinated graphics whilst in flight. See four of these in action in their ‘Lucid’ video promo.

The aircraft had to be structured to fit entirely behind and within the screens themselves causing some interesting aerodynamic effects, and well as the difficulty of managing the considerable weight outside the diameter of the props. They also have to be flown accurately and in close proximity in a turbulent air environment, and so use both lasers and optical flow for position and height control. An interesting challenge. On top of this the aircraft were designed to be stacked and fitted together to make one large screen then flown off one at a time!
Airlift 2 Offshore Delivery Variant
This variant of the Airlift was designed specifically for one of our large offshore energy industry clients. It will carry a payload up to 25 Kgs and features a remote payload release system to allow the pilot to fly from support ship to the heli pad on an oil rig, release the payload and leave without anyone needing to approach the aircraft.
This aircraft is fully weather resistant, has a custom one axis FPV camera gimbal and range sensor for remote landing assistance and can be folded for transportation.
GPR (Ground Penetrating Radar)
As the name implies GPR is used to look for information about what is beneath the ground with applications ranging from archeology to mine detection. Normally GPR would be fitted to a small ground vehicle or even dragged across the ground by a human operator, however this approach is not always practical or in some cases even possible. GPR sensors rely on close proximity to the ground, so to undertake this from a UAV requires operation at very low level and at a very consistent altitude. A grid pattern using waypoints is generated and altitude is maintained using a very accurate laser altimeter and some clever terrain following algorithms.
Flying at this level means the aircraft must have very accurate control and also be highly resilient to wind as any deviation could easily result in a crash. This particular aircraft is extremely stable, produces minimal vibration, and can manage around a 30 minute flight with the GPR allowing for good coverage between battery changes. Altitude control is accurate to around 1 cm.
RF Spectrum Montioring
This Raven variant was designed to carry an extremely sensitive RF spectrum monitoring system. Traditionally such systems are bulky and heavy but Metis Aerospace developed a system light enough to be flown by one of our aircraft. With a payload as sensitive and high value as this, low vibration levels, excellent resilience in difficult conditions, ultimate reliability, quick deployment and ease of use are all key.
The system itself is designed to pop up anywhere at very short notice and monitor activity across the full range of RF frequencies. We cannot disclose exactly how wide a range or number of frequencies it can monitor simultaneously, but it is a very impressive piece of kit!
Airmageddon is a ‘Robot Wars’ type TV show made by the BBC in conjunction with DHX Media in Canada. It features 9 – 14 year old pilots flying drones in a tasks from obstacle courses, to knocking down brick walls with wrecking balls, lifting objects with electro magnets, hitting targets with paint ball guns and more. The show aired for the first time on CBBC at the end of January 2016.
An interesting project as we had to produce six ‘house drones’ (WASP & GUARD featured in this picture), as well as a fleet of bespoke X8s for the competitors to fly. These had to be very tough but also easy to repair as crashes were, to say the least, common!
UAV Smart Winch
The UAV smart winch developed by us for delivery of light payloads to areas where landing is not possible (such as the top of wind turbines), or for placing of equipment or sensors in hard to reach or no access locations (with the addition of our remotely operated dropping hook – not shown here). The smart winch is integrated into one of our removable quick release landing gear systems for quick swapping of different payloads for different functions.
The winch is almost entirely automated as it must be able to operate well away from clear view of the pilot operator. A downward facing camera is fitted, and the winch is able to monitor it’s position at all times enabling the operator to have no worries about deployment height or correct retraction. A simple three positon switch is all that is needed to operate all winch functions. A number of safety systems are included such as overload protection, signal loss, positional override reset and even an emergency escape procedure in case the winch line were to get tangled or hooked to something on the ground.
Unfortunately we cannot discuss the payload or application for this particular aircraft, or the reasons behind why it was developed. However the Hex8 is a truly unique aircraft configuration which offers the redundancy offered by 8 motors, with the improved efficiency of having only two pairs of co axial motors. The machine also maintains the benefits gained by co axial aircraft in handling difficult weather conditions.The Hex 8 folds neatly into a compact form factor for transportation.
