Soma cube – part 2

Some time ago I presented some new soma cube puzzles. If you dont know what a soma cube is, have a look here.

Here are 8 new figures:
1) wall

---

2) stairs 1

---

3) airplane

---

4) stairs 2

---

5) castle wall 1

---

6) gate

---

7) castle tower 2

---

8) castle tower 3

---

If you solved it, we have the solution to
wall,
stairs 1,
airplane,
stairs 2,
castle wall 1,
castle gate,
castle tower 2,
castle tower 3,
