This is our new generator, designed for medium payload drones, his weight is 1.5 kg, with a power output of 1300 watts.

There are an integrated cooling system and an automatic starter built in, it also has an anti-vibration plate.

The fuel consumption is quite low (600g/h) and the generator is capable of generating up to 50 volts.

We worked very hard on it, now we are planning to sell it (the price will be about 1600$), we hope to start pre-sales in a few months. If you are interested in getting one of these generators write to

We are actually making a startup around this project, soon we are also planning to develop a UAV with an integrated super-efficient hybrid generator, it will be made for really heavy payloads and missions with an endurance greater than 7 hours, the targets are SAR missions and drugs transportation.

Sandwich Cargo Drone Project (hybrid propulsion system) (3 min 35 sec)

After a few months of work, the first prototype is ready. In the video, we show some moments of construction and testing.

The propulsion system worked better than we expected, now we are focusing on a new generator that will allow staying in the air with 150 grams of fuel per hour (that's awesome if you think the weight at take-off is 5 kg).

The new frame will have a diagonal of one meter, so we will be able to use new motors with a thrust capability of 30 kg.

We saw that the market is really interested in the type of aircraft we are developing, that give us great expectations for the commercialization stage.

Let's start with the generator on the prototype

This is the prototype, the generator is only for demonstration purpose because the generator at the moment is made from a nitro engine with all the connected problems (vibration and fuel consumption). A good thing is that I can add 4 kg of payload and still fly with this configuration, but without the main part of the generator (the gas engine) this is only an oversized piece of carbon fiber and wood so I made a project with a Turnigy 26 cc gas engine (3 hp) and a sensored brushless for the starting and converting the kinetic energy to a three-phase current that will be rectified with a diode bridge. Here is the project

this weekend I will make some flight tests with the prototype and some videos.

The final new is that I'm going on Kickstarter. Why I'm doing this? simple, I have to pay for the flight school and I really don't know how to get the money for the generator (I also need a px4 system with gps and telemetry). I'm working on a heavy lift cargo drone, that means I need a total thrust that is more than 8 kg (my current total thrust). I will take four SUNNYSKY XS4112S 340KV outrunner brushless motors. All this stuff will cost about 500 dollars so I think I will put this request on the Kickstarter page. If you want to stay informed please sign up the mail list ;

In this month I've worked on my generator, it is composed of a brushless motor, a glow one and a diode bridge rectifier, as you can see in picture

It was able to generate at max throttle about 1.2 kW , starting the motor is difficult, I don't love glow engines (I only figured it now ahah) but the point is that my generator works and with some modifications to reduces vibrations can be mounted on a drone.

What I want to do now is to use a gas motor to generate the energy because glow engines consume a lot more fuel (I will be able to generate 1 kW/h with 0.30 L ).

I have also made a new frame to sustain a bigger cargo system (and the generator)

I don't have enough money to buy the gas engine and also upgrade my old APM system to a new pixhawk one so I'm selling my laptop (I'm a student, and have also to pay the flight school)

But I'm trying, the numbers are good 1kW is enough to sustain my configuration with 2KG of cargo weight.

Hi guys, there is my video test showing my first flight time test with my cargo drone, I get 50 minutes with a 3s 5.2 Ah, if you want to stay tuned about the project sign up the newsletter or just take a look to my site

here is the video

50 minute flight time with 3s 5.2 Ah (5 min 14 sec)

I had some problems to upload the video without the speed 10X cause it was about 7 GB, if you want to send me a pm and I will try to send it to you.

ps. a future prototype will be a hybrid so stay tuned!

Today I've made a new test of 3KG payload drone, I'm working on a cargo drone since 2015 so this is a great result for me, I'm also working on autonomous flight system for my drone there is the newsletter of the project :

In these days, while waiting for the waypoint navigation hardware, I'm working on the new frame for my cargo drone, and on the new box, I'm also planning for 4KG PAYLOAD test, after the first of 2kg, I've now got 580kv motors so I have better a thrust, if you want to stay informed on this project please subscribe to the newsletter: or take a look at my site:

Hi guys, in these days I made a successful payload test of my cargo drone (it's just a few seconds but it demonstrates that we can do it). Another news is that I'm working on the cargo box so I changed it with a more resistant one and now I'm working on the navigation system (based on waypoints).

Hi guys, it's 2:05 am in Italy and I'm still searching for a multiwii combo like this it was a really good offer and I need it for my cargo drone project but there isn't anything similar in and in other stores, anyone have a suggestion ?

This is my little cargo drone, it can lift about 2000g and the maximum flight time is about 50 minutes, I also have a site so if you want just click the link, take a look and subscribe to the newsletter
