So I've noticed a lot of people saying the new sparrow acquired through either the season pass or the purchase of the first dlc is a load of crap or that all it does are flips and spins. I'm here to tell you that's not the case.
If any of you watched the video they had in the news tab showing off the new sparrow they were doing scissor kicks, hands free jumps and a move where you jump partially off your sparrow and hang onto the back end of the seat.(it's got a name when people do it on motorbikes I've just not a clue what it's called.)
These can be done by hitting right trigger or bummer while at the same time hitting up down left or right on your directional pad.
Another cool feature is that if you perform a move through the directional pad and land back onto the ground without crashing, it resets your boost. Giving you non stop stunt action. It's also just fun to do when riding along on patrol or running through a strike mission.
