That's imossible I'd say.
A pair of funkey FRP blades costs around S$70.
An OS50hyper or TT redline 53 engine costs around $270.

If you have a budget of $500, that leaves $160 for the heli which is rediculous.
From other USA-based online vendors, the Knight50 sport costs 260USD while the Knight50 3D costs 450USD.

There was a price cut not too long ago I think.

Pay USD$400 still got 1cent change.
