RE: Syma
They are toy grade.
As florida AKM said – indoors only. This is a case where bigger and more expensive is actually worse – the bigger ones still won’t fly outdoors, and they’re too big to fly indoors.
As far as quality, the symas at $20 – 25 and below are worth the money.
So the question left is will you enjoy playing with a limited control toy (and there’s nothing wrong with that) or are you looking for a hobby grade?
If you want hobby grade, then no, and I don’t even like suggesting a 4 channel coaxial – they get boring real fast.
