A 10x2mm neodymium magnet to reset the remote incase of a freeze. This magnet can be glued inside the rear inflation valve cap with some super glue incase you need to reset the remote on the water. The V3 Boogie motor no longer works for a magnet reset.
A remote freeze can happen for a number of reasons. If it happens to you, send up the crash log so we can try get to the bottom of it.
