i wonder if you could run one with a Co2 Canister, the small little ones, though they would be heavy, they likely could provide greater thrust if a nozzle is added in the end albeit with a very low run time some other ideas, you could have the rocket a little bit more foreward so the thrust is at the very front and use less angle though the heat would have to be dealt in some way
now I'm wondering if running a multi stage setup (where one rocket lights the fuse for the next one) could help improve times, it might even run the standard acceleration+timed lap format under full power, which should lead to some really fast times
