I'm going to do a build with a baffle in the lower section, sticking out, with the parachute fitting into the upper part that slips over the extended baffle section. I understand this is essentially the zipperless design.
My question is (within the bounds of LPR and small MPR), what prevents the shock cord from zippering the upper tube that goes flying off at ejection? Is it just less prone to such, being (generally) lighter?
Perhaps I'm missing something basic. I've read a few of the informative articles I've found by googling, but am missing this basic point.
Thanks in advance!
