Ok that makes sense. How does the size of P3E compare to AO-40?
Could we design a larger version of the P3E spaceframe that would fit
into the mounting ring used for AO-40?
if so would that give us a bird large enough to do what you think
needs to be done, for the future needs of the sat community?
We know that the P3E (AO10/13) shape seemed to work as I hope P3E
will also work. Would not a large version work on the same principals?
