I would like to share our last challenge. I think it is probably the longest flight with a hybrid gas-electric drone:
In December 2015 we published our first record:
All this years we have been doing small improvements, A lot of small improvements that make a very big difference. With the EFI we have seen lower consumption far beyond what we thought possible. The weight of all the components has fallen, The generator has increased the available power....
We are very happy with the result, but I also have to tell you that it is not the maximum time we can do.
Obviously it is not a flight time that a customer can use, It is not very practical to fly with 16liters of fuel in a 25kg MTOW drone. But it does show that it is possible to fly for 6 hours with a payload of for example 2kg
I hope you like it!
