Oh, that B6-0 to 1/2A3-4T sounds interesting....if you can get the sustainer to light via that tiny nozzle. At least the model uses direct staging, so I’m assuming you’re using one of the little Estes 13mm to 18mm red plastic adapters in the stack. At least if I were trying to do this, that’s what I would use.

Do as 5x7 suggests and you could do B6-0 to A8-5 probably.
