Most if not all of the 2 and 3 chanel park fliers are toys, there rc gear is useless and some times ilegall if used in a "normal" type rc plane.
if you have the $150 odd for a park flier and it wont afect your spending on reusable rc gear then by all means buy one.
for my money if you want an electric park flier type plane you are much better off spending the extra $$$ for a picco stick or something similar.
