Here's some pictures we've taken over the past few weeks showing Tachyon III in action (although these pictures are from practice, not the actual competition).
Look at that pitch!!!
A few months ago, we designed some nozzles based on the Rice profile to mazimize the thrust produced by our thrusters. We finally got those nozzles printed (courtesy of Nikolai at the University of Alabama), and, although we haven't done any quantitative tests of them yet, they seem to have given Tachyon III a significant boost in power and performance.
