That is sad if that is how your vendor treats you. We have 2 CTI vendors in the south and they have always covered warranty, usually on the spot if they have H/W & motor in their inventory.Don't bet on it.

If they won't find another vendorDon't bet on it.
Wildman’s used to do the same thing .That is sad if that is how your vendor treats you. We have 2 CTI vendors in the south and they have always covered warranty, usually on the spot if they have H/W & motor in their inventory.
Well, that is not very comforting news. So basically what your telling me is I will be flying Aerotech for 29mm the rest of the year. Good information to know about now. I'm not sure I'd want my customers flying the competition for that long if it were my company. So, will Wildman keep my replacement reload until I want to pay HazMat shipping again? Which may very well be Black Friday.Wildman’s used to do the same thing .
However after waiting for months and in some cases over a year for replacements we can no longer have CTI use our inventory to take care of there warranty issues .
When CTI sends the replacement we contact the customer to let them know it has arrived.
BTW. Cesaroni does not pay for shipping either . Leaving that for the dealer to explain to the already upset customer.
Yes we will hold it until you want to ship it .Well, that is not very comforting news. So basically what your telling me is I will be flying Aerotech for 29mm the rest of the year.

Hello all. I just purchased a 54mm 3g case and 1 spacer. This is my first 54mm case. Is there anything to watch out for on the 54mm motors and cases?
I guess I'm not following things on TRF too well. When and why did people start gluing the fwd closures? Isn't that what the case is supposed to do? Hold the closures in place.These days it seems that LOTS of folks are glueing in the forward closure of CTI 54mm loads with more success than those who are not.

I have a 54 6XL case with a couple spacers and fly 5, 6, and 6XL loads. I usually pick the load based on weather and field conditions, open the package and load the motor. I've never had an issue, my case keeps the closure and nozzle where they belong.
Personally Ive seen a lot of 38mm 2g failures. But I also help out with a team and everyone has to get an L1, but we have a day of every 1 in 3 motors failing. Once we added epoxy we haven't had a single failure.It's also been an increasing issue with the 38mm loads, although not nearly as wide spread.

Did you do the starter pellet modification recommended by CTI?Personally Ive seen a lot of 38mm 2g failures. But I also help out with a team and everyone has to get an L1, but we have a day of every 1 in 3 motors failing. Once we added epoxy we haven't had a single failure.
I epoxy the bulkhead with 5 minute epoxy, add a additional o-ring (cant recall the dash #, bought a bag of a hundred from McMaster), and slather the bulkhead and top of liner with SuperLube.It actually started several years ago, and it's been a continuing issue that gets discussed periodically in this and other threads. There seems to be a high degree of variability in the quality of liner cuts, both in squareness and proper length, and plenty of folks are getting high speed gas cutting type failures in the forward seal o-rings as well.
It's also been an increasing issue with the 38mm loads, although not nearly as wide spread.
As noted by 0011001100 above, 5 min epoxy seems to be the ultimate cure/preventative.

That PN brings up X profile o-rings. Where does one put the extra o-ring?

Yes we drill the delays first then coat the outside edge of the closure in a ting layer and insert it into the liner and then wipe off the excess.Do you only epoxy in the black powder ejection charge after drilling the delay??
No because most of these failures were a couple hundred feet up and about halfway through the burn (based on leftover propellant thickness). Also these are 2 grain motors and already have the fixed pellet from CTI.Did you do the starter pellet modification recommended by CTI?
I have flown many CTI 6-XL motors, mostly L265 and L935 and have never had an issue, however I started gluing my closures in several years ago. However, I have personally witnessed many such failures, including 2 from our group at Airfest last year. The failure mode is almost always the same - a gas leak right below the forward closure. I have been using epoxy on my longer CTI motors for several years - based on both the recommendation of my motor vendor and several other well-known flyers who experienced the problem. It’s far more than just a couple of people, and you ignore the advice at your own peril.Based on what? That a couple people do it? Many do not use double O-rings and do not have any CTI CATOs.
Regarding 2-131 O-rings:

On the "extra" o-ring groove of course....
