Off center grain core - defective?

[Steveo]

I was trying to launch a CTI G54 when I had trouble inserting the igniter. Having never flown the motor, I just assumed that's how it was. After burning out the igniter I took off the nozzle and realized the grain core was off center. Not just off center - it runs down the side of the motor.

I'm guessing that isn't safe to fly...but thought I would check before contacting the dealer. Thoughts?

Is the G54 a moon burner? That would account for the core configuration

Well now I feel like an idiot. Had no idea that was a thing. Thank you.

Its packaging only states it is a G54 Red Lightning. No mention of moon burner. Don't even see that listed on the CTI product page. But good to know it is safe to fly.

I've seen many dodgy BATES grains over the years (even from the largest manufactures) where the central core was drilled off-centre and/or crooked, but this one's far enough off to leave little doubt that it's an intentional moon burner

Def a moonburner, check out that curve

It'll give a fun bang off the pad and then keep a nice long gentle sustain.

Yup that things sends the Mini class rockets to the moon! AND with a quickness.
1lb rocket with 25lb off the pad followed by almost 3 secs thrust makes for fun drag race....USE a tracker or say bye..bye..
