So I have been flying Rc vehicles for the past 6 years but still I need some help. I am soon going to make a new purchase from RC Bazaar but I am not sure what to buy, a plane or a heli. I have flown all kind of 2,3 and 4 ch helis and currently posses more than six helis. My first aerial vehicle was an Air Hogs air plane so well I have got a lot of experience in Rc flying. .So now I am confused what to buy- a plane or a heli. I am looking  at the nano CP 6ch flybarless or (I have not yet decided which model) jet planes. . I am also going to do aerial phtography. or maybe FPV. Should I go for quad copters. Suggest if u know,I have a really small budget.about   12000

Well you had successful experience with planes , then go with planes only . Your budget is fine for a fpv plane . Equipment will cost extra ofcourse .
Multirotor will be best for you i guess . You will get the stability you require.
Helicopters is totally different in this case . In 12K , You hardly get a 450 heli which is inadequate for fpv or aeriel photography .

I have the world's smallest HD camera which 45x19x10 mm in size and weighs 15 gms, so I was thinking I will go for the nano CP to start and experience and also practice FPV. nano CP costs just  9800
