This is the RMS for the 29/40-120 case yes? Assuming yes, buy the -8 and use the delay drilling tool to take it down to 6.
Throwing motors is not recommended.
I sure do know how that ended up - my brand-spanking-new 6" Saturn V had an I284 EZ Cato! Hope we never see the RMS-EZ again, I'd rather have an assembly mistake be mine.
The G80-4 was perfect for my NCR Bomarc which is built fairly heavy. Don't want to Level 1 to use H's.
Was that the old MUCH LOWER total impulse G80 which was sold with a -4 delay or the current EXTREMELY HIGH total impulse G80 which was never sold with a -4 delay?
There were 2 lower impulse versions, the original case with glued nozzle and paper ejection cap, certified around 1995, which was 120 N-s according to the package, or the even lower total impulse molded case with plastic ejection plug, which certified at 94 N-s in 2006 (though AT marketed it at 100 N-s IIRC).
I think this is what you want:
Or, in a different format:
Sad - got that right off the AT website this morning.
Asking round the pits generally will turn one or two up. I have loaned mine out more times than I can remember.
After learning to drill them myself, the drill tools seem inaccurate and uncontrolled. I even pull out my drill bit sometimes with CTIs to take off an extra second and I have the tool. I got into reloads partially to save money, and partially because most of the motors came in 4 and 7 seconds when I needed 5.5 .
