the original design as I got tons of mails for this pen, its available finally, although its a very difficult pen to do so it takes time. The system has been tested over 6 months now, the first VAC are shipping by the end of novemeber (the carbon fiber version)
A video will be posted soon with the pen in action. A really different pen, even for our standards.
