Just checked my Sparrow out (EV-37 Voidstreak). Seems to behave just like the Tumbler (note that the backflip I try shouldn’t have worked, I was just testing rotation speed):

Also, as a bonus, landing tricks after the race ends still nets you completions in the Record Book!

I may have run into a strange issue with the new sparrows. Several of my new racing sparrows have the tumbler "trick" abilities (hold R2 to release stabilizers in the air, use left stick to roll). Thing is, the won't roll. I've been trying for 2 days now, and I simply can't get them to perform tricks normally. Once, I managed to get one to barrel roll, but was never able to reproduce it. Forward flips seem to be possible, but the turn is slower than it should be. I tried several sparrows in SRL and in patrol, same results.

Anyone else?

ps

My guardians kick and superman tricks work as normal.

The only issue I ran into was being unable to equip a normal Sparrow once Bungie locked me out of my totally-not-obtained-illicitly Sparrow. That was the race that I ran with the Starting Sparrow.

Maybe it's your control scheme? All of the Sparrows that I used worked fine. All else fails, you can turn the controller off and back on to see if that was an issue... Or log out of Destiny?

Also, it's the Right stick to roll, no?

It still works for me, but it does seem pretty finicky. Releasing boost in the air seemed to help.

So strange. I'd normally just say "oh well, it's a bug" but the fact that I'm able to get it to work 1% of the time has me going nuts trying to figure out if I'm doing something wrong or can work around it somehow.

I did a few races this morning, and I was spinning and flipping all over the place. Tried several different sparrows, all fine.

Either it's been fixed, or I've clearly gone mad.
