I was looking through some of the early catalogs on ninfinger tonight while watchign the Yankees choke, and found the following interesting

http://www.ninfinger.org/~sven/rock...67/67fsi12.html

from the 1967 FSI catalog.

of note ( other than the F engines being freight only, ala Coasters,etc ) is a few little details I picked up on .

1) if you note the B engines, it;s actually a ' C' according to the impulse numbers of 5.36 NS.

also note the C is a mid-C at only 7.81. ( and a D.915 at 10.02, really a 'hot C '... is this the forunner of the D18 ? ) .

2) of much interest is the F1.3 listed as having a 10 second burn time, not the 9 of the F7 steam machine, same motor ? or redesigned / loss of burn time for a larger initial spike ?

3) this is the one that really got me thinking / impressed me - note the propellent wieghts on these motors, and you realize that the ISP on the E and down engines is over 100, much higher than most BP engines, and actually higher than the 'bragged on' AVI Gold series 90 ISP, interesting indeed.

now where are these great motors when we need em :-(
