What are the specs on the aluminum standoffs found here http://www.ghielectronics.com/catalog/product/371 . Specifically what is the length of the hexagonal and male threaded parts? I believe they are 4-40 threaded, but can somebody confirm?
GHI - Could this info be added to the description in the catalog?
They are 4-40 threaded, and the hexagonal shaft portion is 3/8" in length (and 1/4" flat-to-flat in diameter, if you’re interested).
Thanks Andrew! Turns out, these will work perfectly on a friend’s aeroquad (post crash) frame rebuild. The quad was accidentally turned off at about 30 feet in the air. Ouch! Silver lining - the electronics were unharmed, so the frame did its job, but did not survive. Lost a couple of props, too, but we have spares. We’ve got a mini maker faire deadline coming up fast!
30 feet? Yikes! You’re lucky anything survived that kind of drop.
Good luck with the Maker Faire! Pete and I are doing one (Norfolk Mini Maker Faire) next month. No quadcopters, but we’ll have our usual assortment of toys. 
Ironic part - the pilot was a very experienced RC guy and has spent several sessions getting us used to using his Futaba. The quad owner and I are both RC newbs.
Catalog updated. Thanks guys
Every Faire needs a quad (or three). It’s the new laser
The photo on that page shows the stand offs being used on a lattice work of holes. I’m looking for something to mount/organise my modules. Not even sure what to google for. Hints anyone ? Distributor in UK ?
Thanks

For a custom plate contact Steve Presley (http://stevepresley.net/). You can also Google “Tamiya Universal Plate” and you’ll find several different sizes & sources.
@ Justin, @ Ian, Many thanks. One board ordered, and spookily from the same supplier that I get all my Gadgeteer kit from.
@ davestone - Good stuff, Proto-Pic by chance?
