2. A paintball loader according to claim 1 , wherein the arms are substantially straight.
3. A paintball loader according to claim 2 , wherein the arms project substantially radially from the hub.
4. A paintball loader according to claim 3 , wherein the impeller is made of neoprene.
5. A paintball loader according to claim 4 , wherein the hub and the arms are integrally molded.
6. A paintball loader according to claim 3 , wherein the hub and the arms are integrally molded.
7. A paintball loader according to claim 1 , wherein the hub and the arms are integrally molded.
8. A paintball loader according to claim 7 , wherein the impeller is made of neoprene.
9. A paintball loader according to claim 1 , wherein the hub has an upper portion from which the arms extend, and a separate lower hub extension adapted to be mounted on the shaft, the upper portion and the lower hub extension being configured to mate with each other and not rotate relative to one another.
10. A paintball loader according to claim 9 , wherein the upper portion of the hub and the arms are integrally formed of a first material, and the hub extension is formed of a second material that is more rigid than the first material.
11. A paintball loader according to claim 10 , wherein the first material is neoprene.
12. A paintball loader according to claim 9 , wherein the arms are substantially straight.
13. A paintball loader according to claim 12 , wherein the arms project substantially radially from the hub.
14. A paintball loader according to claim 13 , wherein the upper portion of the hub and the arms are integrally formed of a first material, and the hub extension is formed of a second material that is more rigid than the first material.
15. A paintball loader according to claim 14 , wherein the first material is neoprene.
16. A paintball loader according to claim 9 , wherein one of the upper portion of the hub and the hub extension has projections, and the other of the upper portion of the hub and the hub extension has recesses that mate with the projections.
17. A paintball loader according to claim 16 , wherein the projections comprise splines.
18. A paintball loader according to claim 17 , wherein the splines are on the hub extension, and the recesses are on the upper portion of the hub.
19. A paintball loader according to claim 18 , wherein the projections further comprise a circumferential flange on the hub extension, and the recesses comprise a circumferential groove on the upper portion of the hub that mates with the circumferential flange.
20. A paintball loader according to claim 19 , wherein the upper portion of the hub and the arms are integrally formed of a first material, and the hub extension is formed of a second material that is more rigid than the first material.
21. A paintball loader according to claim 20 , wherein the first material is neoprene.
22. A paintball loader according to claim 21 , wherein the arms are substantially straight.
23. A paintball loader according to claim 22 , wherein the arms project substantially radially from the hub.
