Nick, the belly release works, as it is used as part of the trailer restraint system.
She is fitted for water, but the bags are removed. The last owner made some new ones, but didn't fit them, as he wasn't happy with the result. I have them now, but will not be installing. I don't like the idea of winch launch failure, and a hurried landing with full wings. It comes with an old radio that is functional, Flarm, and some sort of GPS nav system I haven't even looked at yet. The instruments are old but adequate for now. My club has 4 parachutes which rarely see the light of day, as almost nobody flys the singles. I will use one of those for a while.
I will definitely have another look at ZR again and see if I can spot her!
