Stuck motor
I flew my Leviathan on an Estes G40 today. The flight went well, but the motor has seized in the mount.
I've heard the recommendation to peel the label off - but had gotten away with not - until now. At this point, I've got the motor about 1/3-1/2 out before the casing shattered. (Channel locks) Any suggestions for getting the rest of the casing out?

Have you tried using a dowel to push it from the front?

Use a Dremel tool to cut a slot in the casing.
That will loosen it up.

Not yet, Rich.
And thanks for the suggestion, GH. I think I've got a narrow grindind tip that I can reach down into the mount. When I cracked the casing, I kinda hoped it would shatter lengthwise enough to relieve the sidewall friction. But no such luck. I'll try grinding a slot down the length.

I cut 4 slots in the empty casing - I couldn't reach very far in, so I'm not sure they made a large difference.
Then I flipped the rocket over and tapped on the forward end with a wooden paint roller handle. Felt my way I to the motor mount and tapped by raising a couple of inches and letting it drop. Worked like a charm. Leviathan recovered. Thanks GH and Rich.
