Good catch all,
Inspections are still on-going so thanks for the fresh eyes! We'll update

I think Andrew is talk about this leak (circled). It looks like a spray,
and develops during the firing before the fire starts at shutdown.

Great run. I look forward to seeing more come out of this program.
Thanks,

From what we can tell right now, the flame on the engine is the duct tape
catching fire. Inspected the orings and they survived.
Engine is NOS/IPA

Looks like a seal to the top of your chamber was leaking a lot during
the run, you can see quite a lot of flame up there around shutdown. Nice
run though, what propellants?

~2,500lbf NOS/IPA heat sink chamber. Ignited with a Cesaroni Vmax slug.
Full data analysis to follow this week. Will be posted to
