From what I know about the way parachutes work in KSP, I think your opening problem resides in the 3d model. the stock chutes have a part model that attaches, a cap that flies off when the parachute is triggered, and then the actual canopy itself. the "ModuleParachute" code lists these part names and animation names: capName = cap canopyName = canopy semiDeployedAnimation = semiDeployLarge fullyDeployedAnimation = fullyDeployLarge it you notice the stock chutes move independently from the attached part. This Hidra parachute is physically locked to the attach point. spin the pod, parachute spins with it. Spin a stock pod+parachute and the parachute stays oriented with the velocity vector, not the capsule. check the 3d model and necessary components for parachutes.
