If you have additional information (ex: specificity of piloting, various characteristics...) on the hang glider Vulcan by Electra Flyer, you can supplement his card by adding your comment or write to us :
I worked at the Electra Flyer factory when this glider was being developed. It was an attempt at a bowsprit glider to compete with similar designs from other manufacturers. I seem to recall that it lacked pitch stability and had too much spiral instability for comfortable thermalling. Its sink rate was also unacceptably high, according to the test pilots I talked to at the time. At any rate, it was not a successful design, and never saw production.
