Generator on the drone, kickstarter project, test flight and new sketch of the gas generator

Okay, there is so much stuff in the title so 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  ;

500 ml of what will lift 1 tonn, 1 km???  .... Gasoline.... and it weights 180 gm....  Great application!!

Cool, great project.

You really need to switch to ArduPilot to get the most from this. Much better at handling internal combustion engines, and far more suitable for complex missions.

thank you :)

 Auturgy I know that, I really need a fc for autonomous fly and landing

Auturgy I didn't know that ardupilot could  handle internal combustion engines ..how is that done ?

Nicolau , looking better to your prototipe i saw that you still use a battery .  How many amps is your diode bridge ?

Comment by Nicolai Valenti on October 19, 2017 at 10:57am

Hi, the model is this MDS150A 150A 1600V 3-Phase Diode Bridge Rectifier the max I have got from it is: amperage  66 (-+) and voltage 18 (-+)
