An ARR exclusive! Special double liner casting tube and liner sets for long burn C-SLOT, D-SLOT and Moonburner motor designs!
They are available in 54mm and 75mm for Research Rocketry Enthusiasts interested in designing long burn motors. Several examples of C-SLOT motors are the 54mm Aerotech J90W, J180T, K135W, K185W, K270W and the 75mm M650W.
Personally, I'm working on a 3 grain 75mm L350. That should be about an 8 second burn!
These are NOT for Aerotech hardware, they are designed to fit Loki first, although AMW and Gorilla should fit fine.
Here are the specifications and pricing.
