CTI K940 Nozzle shred/shatter

[wyo17]

Flew a K940 this weekend, nice flight and good recovery. What we noticed was a couple of pops at motor burnout. Then noticed the nozzle had fractured. No parts on the ground.

thoughts?

I've seen that a few times.

Always on high thrust motors. Jeroen [CTI] assured me it was not a problem. Just very fast,erosive burn.

Here's one of mine.....

Jim,
Did Jeroen say if it was from passing the casting liner?

Steve,

No liners cast. All recovered.
