Tekgra′s UAV


We started drone aerial photography in 2011, and in 2012 we started to design and manufacture our own drones based on our experiences. Through many revisions, we have come out with a range of drones which we believe can compete with the best in the world within our local environment. How do we know? The keys to a successful aerial photography project are drones that: (i) capture sharp, overlapping images, over a big area-of-interests, within the timeframe window available from the weather, (ii) reach the faraway AOI from a take-off location that is ideal but may not be near the AOI (iii) weatherproof because the drone may encounter adverse weather along the way (iv) reinforced to withstand hard or crash landings (v) easily repairable on the field and availability of cost-effective spare parts from our service centre in Miri, Sarawak.

AIRIS T-SW drone

This is a suitable UAV drone for clients who are starting up their own drone unit. T-SW is a relatively slow flying UAV for easy take off and landing, with stable flying characetristics for up to 30 minutes of aerial photography.

The T-SW parts are easily interchangable in the event replacement parts are required. The body, wings and tail can be disassembled for easy carriage. It is also suitable to be hand-thrown for takeoff, or fixed with a wheel for rolling takeoff/landing.

AIRIS T6 drone

This is a proven medium size UAV drone which we have been flying intensively in Sarawak for the last year.

The T6 drone is a perfect combination of portability, endurance, payload carrying capacity and toughness. The compact five feet wingspan makes the T6 drone straightforward to squeeze in between vegetation during take-off and landings, while giving it good stability while flying in less than ideal weather conditions.

The T6 drone can flies for over 80 minutes and return to home with 20% battery reserve. It can carry a downward looking camera and as well as a front-facing video camera. Both are carried internally for maximum protection.

A large compartment in the front gives it plenty of space for equipment and at the same time absorb the shocks during landings.

The wings can be detached for easy carrying. We normally carry it inside a backpack.

Overall, this is now our go-everywhere drone.

AIRIS S8 drone

This is the large UAV drone we normally use for our oil plantation work. It is also available for sale.

This is a seven footer drone made from EPO foam, which is durable and easily repairable in the field. It has an all-up weight of 4.5kg and flies for over 100 minutes at 50km/h. It can covers over 1000ha per flight.

It carries a stabilised camera mount for either a compact or mirrorless camera. A second non-stabilised camera plus a video camera can also be carried at the same time, but endurance will be reduced.

Options for specialised cameras and lens are also available. For example, if you have a flooding problem or the estate is water-logged, an NIR camera could be useful to detect the soil moisture content, and thus enable you to make a estimate of the extent of the flooding.

This drone carries a full set of telemetry equipment, plus our customised Android App which send SMS about the UAV location every 1 minute. Although telemetry also sends back the inflight data to the Ground Control Station, the duration is limited by the on-board transmitter power and antenna.

In an oil plantation environment, the vegetation absorbs a significant portion of the signal. One would be lucky to get any telemetry data from 5km away. SMS will continue to send so long as there is 2G signal coverage, and in fact, the signal strength increases as the UAV drone gets higher into the sky.

Note on telemetry transmitter: You can install a more powerful transmitter, but the signal strength falls off over distance by a factor of distance squared. So if you double the power of the UAV′s telemetry transmitter, the distance only increase by 40%, discounting the vegetation absorption factor. A powerful transmitter will play havoc to your UAV′s GPS and radio receiver.


One of our smaller UAV drones, popular for plantations and development flying. It has a wingspan of 3 feet, weights 1.5kg and flies for 30 minutes.

Inside its body, it carries a compact camera like Canon Powershot with optional one-axis stabilisation. The coverage per flight is between 150 to 200ha, depending on flying altitude and camera settings.

It comes with its own autopilot and GPS. Telemetry and GPS tracker can also be carried if required.

This is a one-piece design with non-detachable wings, making this model particularly durable in crashes or hard landings.

The picture here shows the S3 drone mounted on an aluminium launcher (optional) which are designed and built locally by us. We are currently designing a parachute landing system for this model.


Our slow UAV drone, for short to medium range work. The photo above shows it with wheel for ground rolling takeoff but hand-thrown is also possible and quite safe as the propeller is on top.

This UAV drone can be fully dismantled into a length of three feet. Fitted with flaps, it can perform very slow landings into the wind.

Comes with a compact camera mounted inside its belly, so the camera is protected against hard landings. The top plastic cover can be removed to fit a video camera like Gopro.

AIRIS N1 drone

The first UAV drone we used is a giant eight footer and weights almost 7kg.

Made from ply and balsa wood with film covering, it can carry a camera payload of 2kg plus another 1kg of fuel for its nitro engine.

The endurance is about 45 minutes. It needs a runway for take-offs and landings.

It has a special, detachable compartment to carry camera, video recorders or other stuff. The camera can also be mounted sideways for oblique shots and controlled with a FPV camera.

We used it to carry a Nikon D300 DSLR camera with a 50mm prime lens, which takes super-sharp pictures from the air. Carrying a full-frame camera like Canon 6D is also possible.

Due to its configuration and weight, the N1 requires an experienced flier to operate.
