1What are the typical uses of MMC drones?
MMC commercial drones are industrial level and they are mainly used for industrial applications. The feature of our solutions falls on infrastructure, which includes industrial aerial inspection of power lines, pipelines, offshore wells and survey for police & army. Recently, MMC is providing oil and mining inspection solutions. Specifically suitable for power line stringing and emergency response to firefighting and disasters.
2Do you provide warranty for your drones?
The warranty is included in the price of our products and it is valid for one year. Of course, there is a possibility of extending the warranty period, it’s depending on the volume of the order.
3How much money should I invest in a drone aircraft?
Due to the large variety of solutions, application, accessories and settings, for the most appropriate answer please contact us at info@mmcuav.com, we will be glad to provide you with the most accurate feedback.
4 Do you provide after-sale service?
Besides 24/7 contact availability, MMC is also responsible for replacing any parts caused by common malfunctions. However, MMC will not take the responsibility if the malfunction is caused by the operators. One-year warranty solely includes spare parts supply. Shipping, replacement, travel and lodging expenses ought to be covered by the purchaser of the vehicle. Additionally, our Russia, German, USA, Malaysia, Indian and Indonesian branches provide prompt and effective service in local areas.
5Do you provide instructions on how to operate a UAV?
MMC provides the UAV flight training, but the training will be exclusively offered in Shenzhen, China. We have professional pilots teaching our customers how to use our UAV and professional engineers will give you the best technical support. It is completely free of charge (meals and accommodation are not covered) and takes one week to complete.
6What is the maximum flight time of MMC drones?
A model of MMC hydrogen fuel cell drone flies over 3 hours.
7What is maximum flight time for A6 plus?
The A6 plus can fly for 75 minutes.
8How much payloads can MMC drones carry?
F6-plus --- 8kg; A6 plus– 7kg; Spider – 3kg
9How often should I charge the drone battery?
As for Li-Po (Lithium Polymer) battery, the care is universal. Once the battery is charged, it should be removed from the charger and being maintained properly. The initial use of battery requires a 24 hours’ polarization. But once the battery is used for the flight, it should be fully charged at the assigned voltage. It only takes 45 minutes to refuel for the hydrogen fuel cell drone.
10What are the safety features of MMC drones?
There are several main safety features that MMC drones possess. Other additional safety features belong to the matter of customization. Namely, when in GPS mode, (the most commonly used mode) the waypoint options allow the vehicle to land or return to the starting point in case of a low power, a low number of necessary satellites (less than 7) or a propeller malfunction. Meanwhile, analytical redundancy ensures that even if one or two propellers break during the flight, the vehicle will remain in the air steadily and be able to land slowly. In case that all of the electronics fail, and the drone is in free fall, a ParaZero tiered parachute will ignite and land the vehicle without causing major damage.
11Do you offer customization?
Sure. Customization of drone aircraft can be achieved easily at MMC and it is our biggest strength. You can raise your requirement for the customizing, then it will be processed by our professional executive managers. We offer a set of products and variations corresponding to various payload ranges, diversified axes, distributary rights and exclusiveness. Thanks to our carbon fiber factory, the biggest one in Asia, we also provide numerous OEM and ODM frames.
12What is your usual shipping time?
It can range from 2 to 4 weeks, depending on the size of the order, and the actual distance of the client.
13What’s the control range of MMC commercial drones?
The distance cover range can reach 2km/ 5km /10km.
14 How could I become an official MMC distributor?
MMC welcomes potential distributors to pay a visit to its factory for the demonstration of our competence, sharing ideas and discussing face to face partnership. Contact us to arrange a meeting – info@mmcuav.com
15In comparison with DJI’s drones, what are the benefits of the drones you provide?
Primarily our drones provide a lot longer flight time of 75 minutes due to the Li-Po battery and more than 3 hours on a hydrogen battery. MMC commercial drones can carry a much heavier payload. All MMC drones have carbon fiber frame, and we offer customized design. The most important thing is that we can take 200+ different payloads with the plug and play connector.
16Do you have some case studies?
You can search for various case studies in different fields in videos column of MMC website. For applications like the power line stringing, the savings are incredible in cost, time and injuries. In 2016, MMC had provided over 1000 kilometers of high voltages towers power line stringing in China, India, Indonesia, Thailand, Nepal, Georgia, Bhutan and Bangladesh. The power line stringing looks simply, but this job can be really complicated in a different environment.

18Can you customize hydrogen composite tank?
Yes. The hydrogen composite tank can be customized to hold 9 liters or 12 liters.
19For what kind of application and customer target MMC has the thought for HyDrone?
We developed the HyDrone because we got a lot of customers’ demand. The most needed demand comes from the military clients. The major application is the long-distance surveillance, such as the border patrol. The top 2 needed demand from the oil and electricity grid companies, the major application is the long-distance inspection. HyDrone also can be used for search and rescue.
20About the operating issues. Fuel-cell technology has the main issue: the stock of hydrogen; in fact, this energy vector must be stocked at very high pressure, which means heavy tanks, how did you solve this problem?
In fact, our clients don’t have to stock any hydrogen in our solution. Normally we provide two solutions: 1. If our clients can get a hydrogen station, e.g. Our client in Japan and Alaska, they can easily access a hydrogen station, we only need to provide them the interface parts and tanks, there will be no hydrogen stock for them. 2. If our clients cannot find any hydrogen station,e.g. Our client in New Zealand, we will provide the whole package to them, which includes hydrogen generator, compressor and so on, but there will be no hydrogen stock neither.
21What kind of guarantees do you provide for the customer about the safety of using fuel-cell and hydrogen? Is there a specific customer service on the power plant of HyDrone?
Indeed, training and service should be an important part. 1. We provide on-site training for drones and the whole station. 2. We will send engineers to install the whole system. 3. For the generator or the power plant, we will send engineers to maintenance in case there is any problem. So far, our clients are all satisfied with our dedicated service.
22In which way can I refill the tank of hydrogen? And what is the cost of this gas?
Refilling tanks by the compressor, all the interface is standard, like injection, within 5 minutes, one tank can be refilled, which is much faster than Li-Po battery recharging. The air pressure is only 30 bar, it is quite a safe level. The cost of gas is up to the local market price. Normally it is cheaper than the Li-Po recharging cost.
