If its an xmas pres idea here's some advice from someone who Managed a Hobbie Shop a few years back.
I have flown a few of these. Definatly not for the beginner..!
Made out of 3mm Lazer cut foam if you crash them its most likely game over and too much glue or tape repairs add too much weight for further flights. Expensive electronics, brushless motor and lithium battery which don't go well with any bad water landings. Great fun though.
