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 firstname.lastname@example.org
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.
