Hi Jim
I have managed to obtain a copy of your plan & and the build article.
This will be my secong build, the first is a BB Super 60 which is now ready for covering. The Jocasta looks the ideal follow on trainer.
Looking through the plan, build article and this forum, I cannot find any mention of how you hinge the ailerons. I once read that you can use solartex for this, can you please offer some suggestions
Regards
