I am still waiting for you to explain why a propeller powered UAV requires "large wings" to travel long distances. It safe to say you do not understand the science behind these topics. What you're seeing in Arash UAV vs something like a predator UAV in terms of wing size is something called Aspect Ratio.
View attachment 705310
Arash has a relatively low aspect ratio and predator UAV have long aspect ratio. Both have their own benefits such as lower inducted drag vs parasitic drag. Inducted drag is higher at low speed
and higher altitude.
Some wings are short and stubby, while others are long and skinny. What's up with the difference?

A system like Arash will not be flying at higher altitude, certain not during most of its all flight path. Another advantage of using a high aspect ratio is to help create a STOL, however this does not apply to Arash given it utilises assisted launching, i.e it does not require runways.
With regards to the speed, low aspect ratio in Arash are useful given it is relatively slower:

Another factor to note is something called wing loading. This is a component of wing size and weight, Arash suicide UAV similar to cruise missiles have large wing loading, again this has its own benefits. Note in this cause, speed is not part of the calculation.
Given the design requirement of Arash, i.e use as a suicide UAV which spends most of its time flying at lower altitude and lower speeds, it is a matter of aerodynamic illiteracy to claim it should use "larger wings". What aspect ratio you use depends on many factors such as mission design, practical needs such as storing UAVs in launch containers i.e compactness, shape of the systems etc. Therefore you cannot determine what the range of a system solely by looking at the wing size. Thus, do yourself a favour and do not talk about matters beyond your understanding.
