BFTA and Core alignment done same way as marking out fins: https://youtu.be/_sWssDOyFms

It requires a 3in phenolic tube 30in long as well as a 3in plastic nose cone.

You will also need 4-40x0.5in countersunk screws to build the cluster core and attach all components.

Be sure to use a large parachute 24-36in to ensure soft touchdown

The BFTA screws into the phenolic tube 18in from the bottom of the body tube. Ensure it is aligned with the cluster core as 1 hole of the cluster core Top Plate and one on the BFTA will be drilled out for rail buttons.

The BFTA also serves as a nice location to mount a shock cord to.

The entire rocket is printed from PETG aside from the slot and screw fins which need to be ABS or PLA.
