I blast for a living. My charges are NOT "back water slapped together piece of shit."
Dynamite is a joke lol. Directional, low velocity unstable garbage from a bygone era. Still has some limited uses, but overall has been relegated to lampoon. Get rdx and some A140s. Or better yet, grow a set, and get some HMX. ??
The cologne family of engines?
Not pieces of shit by a long shot.
Quirky, pencil-and-paper V4s and V6s from a bygone era. I like them because they take a beating and keep going, plus I can basically do whatever I want to them, and they keep going.
Otherwise, they're certainly low power density, smallish, and excruciatingly difficult to build for power.
