...I am sure it is something I have gotten out of proper adjustment.
Hi Burke. A few obvious things come to mind to check out -
1 - Is the Prussik knot that connects the rear sails to the keel still symmetrical?
2 - Are any of the connections twisted at the tips?
3 - Is that keel fitting twisted at the tail?
4 - Any obvious damage or stretching?
5 - Are you putting it together differently (spreaders)? Try swapping them side-to-side, sometimes the tapered tubes will flex differently.
6 - Let me know if I can be of any help!
I have been waiting for the opportunity to fly a 61/49 but there isn't anybody around me that has one.
Gary, we have enough history that I'd be happy to send you mine to try out if you'd like.
Nice video Jürgen, thanks for posting it!
