Hi all,
Parallel I've started with spars and centrecase. Building the rectangular hollow mast, some thaught struck me: why not hollow spars as well? The boom should go rectangular as well easy, but the yard should stay round for aerodramatics, so birdsmouth probably is the way to go. Lots of work, but reduced topweight is always worth a thaught.
For I have no idea of the useful dimensions, I have started with solid timber.
Mik, how do you think about hollow spars and their dimensions?
