Looks like it, the specs match up. It's confusing because they show up under Aerotech, whereas the C18W and D20W released in late 2020 are under Quest Aerospace. All White Lightening, all Q-Jets. There should be consistency in the assignment, either all Quest under Quest, or the Quest engines split by propellent (BP under Quest, composite under Aerotech). John Coker, if you're following, maybe you can weigh in.
As far as hazmat, that's confusing as well. The manufacturer may say non-hazmat, but vendors may lump them into hazmat because they are composite without really looking into it. Buyer beware. As for what the designation is on Thrustcurve, that depends on the poster. Another JK question (the C18W and D20W are listed as hazmat, but I think they are not according to Aerotech/Quest).
