"Awesome addition to the Mammoth Rocket!"
Booster worked as it was intended. We got an awesome slow-mo video of the stage separation!

"Great Idea!"
FinBurner (
This is a very simple to build booster that can work with the newer Pro Series II kits. I bought this one for my Ascender and it works great! Construction is quick but still creates a strong, solid product.

"sturdy plastic fins"
Someone (Somewhere)
The fins are two hollow sections with reinforcing ribs that are to be glued together. This is a very strong design.
