In searching threads about this I have seen some postings that say using the forward closure for recovery attachment is fine, while others state it is a bad idea, as the forward closure is not robust enough. Does anyone have any input on this? .
Been using them for years, actually making my own by simply self tapping a 1/4 E-bolt into touch hole after emptying the BP. It's more than robust enough. You would have to pull out the forward closure from the case.
Thanks all for the replies. Regarding the CTI 54mm threaded forward closure, that's the one I've seen some posts on stating it is not robust enough to be used as a recovery attachment point. But I don't get why else they would make a threaded forward closure one can attach a eyebolt to.
Some one not knowing do-do would say those things. See my first reply above. [this is how rumors get started]
It may be strong enough to use as recovery anchor, but do you want to gamble? I'd just pair that with the Aeropac min dia retainer or a home-built version (bulkhead plate with eyebolt through it.

What did we do before the Aero-Pac adapter? I've been around long enough ......used the eyebolt.
Why are you gambling? Designed & approved by CTI, more than ample for minimum diam. use.
See my first reply again.
I am not sure I would trust that plastic CTI forward with a 20 pound or more booster section.
Not made for that, if rocket weights that much, should be a recovery harness somewhere. It's minimum diam..
Interesting. Where would one buy this? I never saw anything like that listed on CTI's website or anyone who sells CTI reloads like BAR, I guess I haven't looked in the right place.
Wildman, Ken Allen, has them, probably any major CTI dealer. I 've purchased from both.
I don't even know where to look on web. I think 12.00 It's a call & ask thing. Now after talking to Jeroen,I just make my own for .29 cents as mentioned above.
BUT: K-300 come with them. Several other 54 long burns may.
If flying a motor with threaded hole and NOT using it for recovery, be sure to PLUG that hole with a bolt or glue or risk possible blow by if delay grain burns faster than motor. [heck THAT never happens does it...lol]
When purchasing one for use be sure to check diameter & fit. Ones for long burn are smaller diameter due to liner is thicker [long burn XXX] LB threaded closure will be sloppy loose in regular motor!
Older units just fit in.
Newer units have an extra O-ring on lip that fits INSIDE liner to seal better. Most 54's now have that feature where needed.
Remember these are minimum diameter specific. Anything larger should use a harness.
Happy flying!
