The IP is a accessory for the TM which fits the MK Terrova and PD models, it does not affect how either model deploys or stows. I have a Terrova and it deploys/stows very easily. No pull rope just a lever you push down, and lift the motor head up, and it almost (will) fall overboard so to speak. To stow it, push the same lever and pull up on the motor head and lay it down in its mounting bracket and lock it in place. No spring assist on the Terrova. I can't say on the PD, never had one.
