Quoted from Jimmyhonda:
So, I see the raptor behind the raptor pen has a spring below it. Is that raptor supposed to move? Mine is just stationary. I don’t ever notice it moving. Am I missing something?? Thanks fellas.
It's not a spring, it's a bunch of weights on a screw post that weights the tail of the raptor down.
A ball hitting the plate in the raptor pit "punches" the plate under the tail and kicks the raptor forward then the weights help return it to the start position.
Try it with the glass off ( you should be able to move the Raptor by hand freely) and launch some balls into the pit by hand...you should see the raptor lunge forward...it's a quick lunge and needs the weight and speed of the ball to deflect the plate...it's all physical reaction, not a solenoid movement
If not...it make be stuck on the plastic ball deflector, or the Raptor hind leg screw/nut may be too tight preventing movement...I actually took the washer out of my Raptor leg assembly to help the Raptor move more easily (there's a post and groove track in the Raptors leg's the washer was allowing the post to come out of the track), and loosened the stack of weights screw on the tail to allow the random weight movement to assist the return travel and also prevent the tip of the rod holding the weights from getting stuck on the plastic...now it's super speedy
