[SPAM] OS 1.40 header

[Anthony Romano]

Don't know the weight of the OS header but my setup of cut down header, two 
teflon couplers and Al wing tube extension is just under three ounces.  
Maybe the Mintor version is lighter but I would be surprised.  Over four 
hundred flights in my HydeAway and zero maintenaince.
It is a good idea to use longer header bolts than the supplied with the Macs 
header.
