RE: r/c decoys
i tried doing something similar. got the "waverunner" from radioshack for $30. it's a little guy riding a jetski. it has two shrowded props that work independantly, goes left right fwd and back. i took off the little guy and mounted a deke on top of the waverunner, it was top heavy. so i removed the deke and painted the toy to look like a duck (head, bill, wing and patches, etc). it's ok for making waves on a still day, but the remote doesn't have a very long range. it's worth a $30 investment.
