Today I didn't try to "pull" this one until I got home - it was STUCK!
This is the new Corkscrew rocket, my version is BT-5 based. I rarely build models with the thinner BT tubing, they are easily crimped when removing a stuck engine.
To get the engine to release from the body tube side wall, you can crush the engine casing and clay nozzle.
Work close to a trash can and use pliers to crush the casing. Be careful to only grab the exposed engine casing, not the rear of the body tube with the pliers.
Squeeze the pliers and the casing will collapse. The clay nozzle will break apart into small pieces and dust. Shake the broken nozzle into the trash.
As the casing is collapsed, it should release some of the tape hold.
With the nozzle gone, more of the end lip is exposed so you can get a good grab with the pliers.
Pull the engine out without putting any stress on the upper body tube. Never grab a BT-5, BT-20 or BT-50 too tightly. You'll crimp the thin tubing.
If it doesn't come out easily on the first pull, crush more of the casing and try pulling again.
This tip works best on Micro Maxx and 13mm and some 18mm engines. The thinner the casing wall, the easier it is to crush and pull.
