Garrace
Well-Known Member
I am in the process of assembling this motor and have question grain placement. The grains when installed are shorter than the liner (normal) part of this is taken up by the smoke bulkhead shoulder and part is taken up by the liner seating grove at nozzle end of the case. That still leaves some space. Dose it matter if the grains are tight against the smoke bulkhead or the nozzle end?
I tried to contact Aerotech but I think thats going to take awhile to get an answer.
Thanks
