Are they powerful enough for a reasonably built 1/100 Estes Saturn V with a 29mm mount ?
Or are we talking Cruise Missile ?
Will they be sold in the proper 3-pak fashion ?

How about some PORT-BURNERS with a REALISTIC peak thrust level instead ???????
Hmm ?

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
