Excellent data on 'heavenly body':

www.vqmodelaircraft.com has the struts that we need:
two 1/2" straight struts.
one 7/16" right offset (from pilot's view, want fork pointing back and offset to the right).
I'm going with the short offset: 2-2 7/8" wheel.
They also have the long offset: 3-5" wheel.
they also have machine guns: looks like at least 10 are needed.
(he has good prices on these struts and the guns are presently on sale).
