Fully-Function Retractable Grappling Hook Gun Vs Jetpack Answered
Hi. I'm new to this site that I discovered on my quest to create the above mentioned item. A fully-functional retractable grappling hook gun. Vs, however purchasing a jetpack. I need blue-print of how to make a strong enough retractor, I already have a grappling hooking in mind. Here goes. Nothing like planning to dawn a cape, just like to keep up with the times. Been into mobility for awhile.Thank you.
