Hi everyone,

We are currently using a DLE-20 engine for one of our drones. However the range and endurance is only 3 hours and 300 km. We are looking for an alternative to give a better performance. Can you please suggest any ideas as well as an alternative power system that would provide better performances?

Thanks!

Woah, DLE-20 and 3hour 300km -> 100kmph , that is awesome...would like to see it..

is your airframe composite ? if not then consider a composite this will lighten
your total AUW and enable you to carry more fuel.


also try to get a diesel conversion kit for your engine.
diesels are more fuel effecient and you will better endurance for the
same amount of fuel.

It is made of composites. Weighs 10 kg without fuel and supports upto 3litres of fuel.
