I am trying to build an electric aircraft which will have the maximum flight times..
I will be having a maximum payload of 400 gms excluding battery ..
Please guide me for selecting a model which will be robust at winds and can fly at higher altitudes..
I am currently flying a balsa plane of wingspan 96", which is a pusher model and sadly it gives a flight-time of only 20mins with a 4s 5000mah battery..
But it is quite robust at heavy wind conditions..
The website marcus UAV is using the model Zephyr which is a flying wing..
http://www.marcusuav.com/zephyrairframe.htmIs it that a flying wing is much more efficient that any other models..??
Please suggest me a DIY model which will give me the maximum flight times and can fly at high altitudes and heavy wind conditions..
