The Black Brant XII (a.k.a. Talos Terrier Black Brant Nihka) is a classic sounding rocket built in Canada. The Black Brant VII has reached altitudes over 930 miles ( 1,500 km), higher thatn the orbits of the shuttle and space station.
With Estes new Black Brant XII kit, I will be looking to modify it into a high power rocket with a 29mm H128W booster. I just received my kit a few days ago and am planning through how to go about this

I took the time to model the the plastic transition pieces in Fusion360 and will have a link below to download STL files for 3D printing
