hey the coin thing is a pretty neat idea,better than opening the plane. i trashed one opening it up , the foam simply ripped away from the orignal seams.i will have to try this. i fly mine in the wind with about 5 to 8mph, i almost gotit to where i can hover pionted into the wind. my 7 and 12 year old fly there own . they have never flown a plane before and had ifgured it out in about a minute or so .
