there are no $100 helis worth having.
blade cp is a fun little heli.
i would recommend that as a beginner heli only because it is cheap.
it is alot harder to fly than a larger heli.
larger helis are more expensive.
get you atleast a 30 size nitro heli. cheaper than a 90, alittle less intimidating, alittle less atable than a 90 but a good start.
if you got the $$ get a 90 and get someone who knows how to fly helis teach you. you wont reget it.
