New hybrid drones are being designed here at the sandwichaero laboratories, smaller and cheaper than our actual 2000W hybrid drone.
next model is going to use 15" propellers and a 1000W generator, a configuration which will provide 5 hours of flight time with a light payload (up to 500g) and more than 2 hours with a medium payload (up to 2kg).
You can buy our 2000W hybrid drone from here: https://sandwichaero.com/products/hy1000-hybrid-uav

| Hybrid drone generator engine Test (4 min 32 sec) |
This was one of the tests on our heavy drone (14+ kg).
We plan to sell the generator separately and also a complete hybrid drone system with a 4 kg payload capability with 2+ hours of flight time.
The generator specs are
weight: 3.6 kg
compatibility: compatible with any aircraft with a power consumption of less 2000W, the support mount can be customized depending on the needings of the customer.
Voltage: 12s (can be modified on request)
specific fuel consumption: 1L kW/h
dimensions: 20 x 30 x 40 cm
The generator is hybrid, this means that even in case of generator failure the drone will still fly.
The generator vibrations are suppressed before they can affect the frame.
Fuel: gas-oil mix at 1/30 ratio

This is our new concept for a long-range fixed-wing UAV.
The benefits of having a long-range UAV in search and rescue operations as well as in urgent transportation of blood and medicines are astonishing in terms of costs and effectiveness.
Surveillance operations and mapping are also two sectors where a similar air vehicle is essential for an efficient and fast survey.
From aerodynamic simulation: Speed range 20-30 m/s
Max payload 1.5 kg
Range: 600km (depending on payload and wind, using NCR batteries)
Power consumption 22 - 40W
High stability.
Wingspan is 1.8m, making this drone easy to transport with any vehicle.
We work to take into the market something that may improve the services also in developing countries with big land fields and under-developed street networks.
Soon the test phase will start,

Ever wondered how to cut wood, plastic, thin carbon fiber pieces in order to make you drone frame, the ribs for your fixed wing plane or whatever you are trying to fabricate?

We are now sizing our medium aerial platform down, to get a cheaper product with an awesome flight autonomy.
It can be equipped with both DJI N3 or Pixhawk flight controller.
16" props are used for this smaller quadcopter.

We finally have our hybrid UAV, the HY1000
Wheelbase: 1000mm
No payload weight: 4.5kg (no fuel)
Max take-off Weight: 10 kg
Max speed: 10m/s
Max flight time: Over 4 hours
Voltage: 22V
Generator output: 1 kw
Generator weight: 1.6 kg
Fuel tank: 1L (Customizable)
Fuel consumption: 800g/H(Max)
An internal combustion engine consumes gasoline and spins a generator to ensure a 22V output. Besides this, a 6S lipo battery package is also installed onboard to offer emergency back-up power for quick climbing and quick maneuvering.
With 1kg payload, the flight time is more than 3 hours, and with 3kg payload like a high-end camera, the flight time will be still more than 1 hour.
Check out it here: www.sandwichdrones.it
Our hybrid drone is powered by the GS1000 Gas Generator
This generator is suitable for UAV systems able to lift 1.6 kg plus the fuel weight, with a maximum power usage of 1KW.
Fuel consumption: 800g/kwh
Generator weight: 1600g
Accessories weight: 150g (backup battery)
Generator dimensions: 21 x 16 x 9 cm
Can be mounted on standard 12 or 10 mm standard tubes for gymbal support or any other support on REQUEST.
All our carbon fiber parts are CNC made.
You can buy one from here https://sandwichdrones.it/products/g...brid-generator
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 nicolai.valenti@gmail.com
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.
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 http://eepurl.com/cUJnJr ;

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.

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: http://eepurl.com/cUJnJr or take a look at my site: https://www.sandwichdrones.it/

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 https://hobbyking.com/en_us/multiwii...ps-module.html it was a really good offer and I need it for my cargo drone project https://www.sandwichdrones.it/ but there isn't anything similar in amazon.it and in other stores, anyone have a suggestion ?
