Flying by myself one day I lost my trainer in a patch of trees. It had been gone for several seconds, and I was getting ready to collapse the antenna and turn the transmitter off when lo and behold my plane popped back up out of the trees. I do not know how many lives a plane has, but that had to use up most of them. Only the cows know what happened to that plane for those several seconds.

Moral of the story, go back out there and give it full throtle and full up elevator and see if it will pop up from the trees.
