Fair warning, without a tensioning system that can feed line back out if it reaches a tension limit, you can force the glider to stall.. I've done it.. Think of it like a fishing reel. I hope youre using a genuine quick release, and carry a belt cutter in case it gets hung up.. thats happened to me before as well. To escape the lack of tensioner.. maybe think about creating a failure point that is designed to break long before you potentially overload the wing into a stall. Like a weaker rope that breaks after XX pounds instead of XXX pounds; and play around with it. Cheers
