Buckaroo is a queen bee shuttle stabilized at one or both ends by an eater 1 in such a way that it can turn a glider. The glider turning reaction uses a banana spark and is colour-preserving. The mechanism was found by David Buckingham in the 1970s. Its name is due to Bill Gosper.

It's also possible to reflect a glider 180 degrees with a buckaroo, with a different return glider lane and timing than the 180-degree reflection performed by the pentadecathlons in a relay.
