Mayf;
10lbs/second @ 2000lbs ST is my recollection. Yes, like most liquid-
fuel motors, it can be throttled but over what range, I dunno.
Diesel or propane should probably work but are they hypergolic with
RFNA?
Me drive that thing? Maybe after enough Coors..... maybe not.

Hey, Neil...can we get RFNA anywhere? What about the special space suits
required when handling the stuff? I wonder of we could convert the motor
to use propane or diesel as the fuel...aniline might be hard to come
by? Any idea about the flow rates at rated thrust? Powered through a
full 2 miles, hit the flying mile and then shut off? Is this engine
throttleable? Yeah, we could just kill the oxidizer then the fuel. That
would work. After running it as a 2 wheeler and getting the FIM record
then we could add a couple of "training" wheels and runn it as a four
wheel vehicle also. You gonna drive it? Not me...Joe? Plus no traction
issues at all!
mayf, waiting for the dew on the grass to dry so I can cut it..
