As a kid we had a Mynah bird, who ate mostly canned cherries as I recall. It could do a perfect ring, and "you're wanted on the phone".. which was funny the first 137 times.
The trim from launch doesn't worry me (yet) - this thing is light enough to test glide in long grass, and we have gobs of that up at the glider field. I'll probably trim it out with hand tosses.
