Thank you all and thank you King for links.But in Serbia RC is not very popular so we have 2-3 stores but they have just several models.This two-flying fish and Fast3 are the best electric models they have.They have several nitro models but they are very expensive for me.For example Fast 3 is 65 euros = 100 dolars and Flying fish is 45e.But nitro models are over 300e = over 450$.
I have never tried flying so I am not sure I will get serious in this sport.For now it would be just messing around,but latter maybe I get something serious.
