You know what I would do.
1. Use a pin vice or use an exacto knife to get your whole back.
2. If you did it my way,(which I thought ahead when I did this, thinking of the stand inevitably breaking off), I don't glue the flying stand in the hole, I also don't glue the turret on (for hammerhead) or the hatch (for devilfish) I just put it in, if it slips out too easily, then paint the inside of the hole, and if it snaps off, you get something pointy and push the tip of the flying stand all the way through the hole, then take the turret or hatch off and let the piece come out through their, then break the broken pole off of the base, and take a spare pole (which you will have, you collect tau), cut the bottom connecter piece off and glue that in the center off the base, then stick it in your vehicle.
Remember this for next time. It saves a lot of trouble with a pin vice.
Also I can't believe your sister ran over your tempest! Id take her keys and scratch up her car, then deflate the tires, then put water in the gas tank, and write retard all over the car in paint.
That's getting even, the fun way!
