Another Anti-Zipper

well.....
for better or worse here it is...






In my Estes Tomahawk...

UNTRIED however!!

I note:

that although the plastic practice golf ball fits nicely in this tube (and also becomes a baffle!)

Shock cordage can get between, and behind it, and so I am going to put some wadding on top of it and pack everything carefully. Like 'chute first and cordage last as best I can.

anyway, just going to have to try it out....
(oh and my cord is attached to the top of the motor mount tube.)

Upscaler has a similar idea that he submitted to the Apogee components Newsletter. He uses a Tennis ball

lol, those are soft and fuzzy too

for smaller rocket tubes, I was thinking a paddle-ball ??

these golf practice balls, I do have some concern about the edges of the holes....could cut into the cord.

History repeats itself far too often....
It's been done before about 20 years ago......
For bigger rockets though.

I'd be afraid it would melt, if you don't put some wadding behind it. If it's Kevlar, I wouldn't worry about the golf ball cutting it. Great idea.

Ya, kevlar cord.

For smaller airframes, petstore mini-tennis balls fit well. RexR gave me this one for my Interrogator G.

For larger air frames, I use with a pool toy / noodle or pipe insulation.
