The Mach1 web site has an Open Rocket simulation for this fiberglass BT-55 rocket, but not a RockSim file. I downloaded and ran Open Rocket, and I can open the simulation, but when I try to "Save As" a RockSim file, it throws a Java exception. Has someone out there already done this conversion, or can someone try converting it for me that is a regular Open Rocket user? Thanks!
