GrumpyM4 0 #1 Posted July 20, 2023 Odd question: i'm looking at getting an MC4 converted to a bottom throw (and adding an AAD pocket) for shits and giggles and am curious if anybody has ever done a pro pack on a canopy like that or is the flat pack the only real way to do it right?

riggerrob 643 #2 July 20, 2023 Flat-pack is probably specified in the old military manual. If I remember correctly, MC4 was introduced before PRO-packing became the norm among civilian skydivers (mid 1980s). I have PRO-packed hundreds of tandem canopies that are similar in size to MC4 canopies. They all opened fine. 1 Quote Share this post Link to post Share on other sites

I was warned that MC4's will always have a somewhat hard open, which is why i'm interested in seeing if a pro pack is possible as there are ways to increase the snivel. I'd like to have this as an occasional play rig, and i also don't want a crap opening when i use it. Quote Share this post Link to post Share on other sites
riggerrob 643 #4 July 22, 2023 The first step to making most canopies open softer is to roll the nose. If you want to roll-pack the entire canopy, then look at the Strong Dual Hawk packing manual. I have seen a few civilians roll-pack an entire canopy by laying the canopy on its side and rolling the nose past the B lines. Then they grab all the steering lines and roll them forward past the C lines. 2 Quote Share this post Link to post Share on other sites

The method called "factory pack" back in the day is very close to the reserve packing method - not propacking. The "roll pack" as it was called back in the day is much different.
