I'm working on my level one cert vehicle which is a 2.6" fiberglass Madcow Super DX3. Once all the misc hardware is installed, it will weigh about 5 lbs. Everything I can find online suggests that I should aim for a ground impact speed of 17-22ft/s but according to OpenRocket, that suggests I'll need a 45"-50" parachute (50"=19.6ft/s ground impact velocity). Given that it's a 2.6" airframe, I'm concerned a parachute of that size won't fit wrapped in a Nomex blanket and if it does, I imagine just barely. How tight of a fit should it be? If it doesn't fit, what are my recovery options? Currently looking at the PAR-50 from Top Flight Recovery but it doesn't appear that they list packed diameters, unfortunately. Many thanks. -JT
