I second that. I think the Dolphins an excellent 2nd plane, and it really does take a beating. Some dummy ran it into a post and it held up pretty good ; that dummy being me
:P Anyway, it will teach you more about sport planes and how they fly, it will do some mild aerobatics, and yes it does go pretty fast and will perform well if you have sufficient throws, although I recommend you keep the throws down for the first couple flights

And who could resist the price ... $99 ; most sports are about $20-60 more, depending on which one.

I third the Dolphin. You can't beat it for the price and it handles like a dream.
