With hovers, unless you've got a clear line ahead of you in case you fail the skid roll, or a really good driver, move at Flank speed ONLY in a straight line, saving one movement point for a turn at the END of your move. The skid roll only applies if you move forward as part of the same move after making a turn. You can move and turn safely at Cruising speed with no fear of skidding.
One trick is to find a long, straight row of hexes, and position yourself at the one end of it. Next turn, or when the enemy shows up near the other end, you race at Flank speed down that clear row, building up an impressive penalty for any shots against you, and taking a shot at the opponent. The following turn, you back up at Cruising speed along the same way you came, or backing up around a corner to break line of sight until you can make another high-modifier run. Hovers, due to their fragile air skirts presenting a great target for motive hits, are best used for rapid passing shots and slash attacks with high modifiers, rather than duking it out with a far less vulnerable opponent.
