The Main takes anywhere from 500-800ft to fully open. However, I have experienced 1K openings before. The reserve should open in less than 500ft. The minimum deployment altitude is 3500ft AGL based on cutaway decision altitude. All cutaways must be initiated by 2,000ft to avoid a dual canopy deployment after the 1500' threshold of the 1500A Mil Cypress. Both Reserve and Main are identical and use spring loaded pilot chutes increasing the risk of malfunction- the military has recognized this in the development of more recent systems. An MC1-1D is a Static Line only Rig with a semi-steerable round canopy. The main deployment is the Universal S/L Snaphook. Your only ripcord is the Reserve handle mounted on you chest reserve (MRPS/T-10). MC-4 is a good system for jumping a flag but be careful under high/funky wind conditions. If you can't put 300lbs under the canopy it gets unstable at low altitudes when high winds roll off bldgs or tree lines. Tandems are safe in those conditions because they weigh the canopy appropriately. Please acquire this system legally or the Feds will catch up to you quickly. I suggest you research the Emergency Procedures for the system and the 1500A.
