Well if you controller took a crap so soon I'm sure they will replace it. Thats funny about the other guys saying its not flying, these thingsare harder to learn to fly than any glow plane I have flown. Alothough when y ou get good at it then anything short of a helicopter shouldnt be a problem to fly. Plus the power to weight ratio is pretty amazing compared to most glow planes, other than some of the better full blown 3-D planes. I bet if they tried them theyd love them as much as the people that fly only these things do.
