There is a spare parts guide for the Pulsar at http://www.flexifoil.co.uk/products/spareparts/Flexifoil_Pulsar_Sp_04.pdf that shows you where various bits go and how long they are.
I hope this helps!
Are there any people here who are at or are going to Loughborough Uni this year? Been there for 2 years already and I 'found' kiting at the end of the last academic year! Just wondering if there will be anyone to fly with on the unusually windy days in Lboro!
Also see http://www.flexifoil.com/community/forums/showthread.php?t=43121&highlight=pulsar+spine and http://www.flexifoil.com/community/forums/showthread.php?t=32285&highlight=pulsar+spine here on the forum for more info, sounds like spine breakage on Pulsars is a common thing!
80cm Approx according to Flexifoil...check out http://www.flexifoil.com/products/spareparts/Flexifoil_Pulsar_Sp_04.pdf it's the spare parts guide for the kite!
I hope this helps!
