I was told to use whatever the diameter of the tube is that is how much you should have for the length of coupler going into the tube. So for a 8" tube you should have 8" going into the tube.Building a 1/2 scale Patriot. The air frame is 8". I converted it to a DD using the 12" coupler for an E-bay. Is there a rule of thumb as to how far the E-bay should slide into the aft section that it will eject from.
A little short. The use of sheer pins should help with any "wobble" the coupler may make within the body tube due to the shorter length. Three or four sections of 1/16" styrene rod works well.The ring slid down on me when it was drying, I only have 5" on the aft side. I can not flip it around because of the cut I made on the ring. Not a perfect cut.

Cool!! Sim and see where it goes thoughSome how I missed your offer Ben. Heck yeah, if we make it I'll take you up on that! Thanks.
Ben, 9800ns is an M. Over 10240ns is an N.FYI MDRA has a 16,900' waiver.
I do have a Super Polish Rojo N3300 in the 76-8000 case I want to try. You up for it? I am going to fly it on the Test Stand first and see what it comes out to, myself and a few guys don't believe it will be an N3300 (9800Ns) in the 8000Ns 76mm case. Even though it has a 1.06" nozzle and will have mach diamonds out the @ss
Ben
sorry I spoke wrong. I was looking at my dads 4 grain 98mm in burnsim, thats 9800Ns.Ben, 9800ns is an M. Over 10240ns is an N.
Should be nice, that's a nice case and the red should be forgiving for that case.
