Arent they the best fun ever!
My little boy is 20 months old , and can spot a "copter" a good 30 seconds before dear old dad! He even knows if its me or not in the air. Had his first flight when he was 3 weeks old, well that is if you dont count flying his mum around when her contractions started, to keep them going, plastic bag on seats and all!
I also have model helicopters and planes at home and the first thing he wants to play with is the copters, he also prefers helicopter magazines to winnie the poo. He only likes planes if they do aerobatics, and when asked which he prefers its always the copter! (well trained)
A future pilot is born.
