Re: Storm the Castle B

Just got back from regionals. Places 3rd in Compute This but Storm the Castle was a mess. The event supervisor got sick so a volunteer ended up running the event. The volunteer didn't have the CW weight or the projectile weight so he ended up taking a CW from another kid in the competition along wi...

Re: Storm the Castle B

With 1 kilogram of counterweight and 55 gram projectile we were able to go about 6.1 meters. When we went any higher with the CW, we hit the ceiling! (we were practicing in the hallway) So you think this is a good distance?

Re: Storm the Castle B

It specifically says in the rules that the center of gravity must not drop in the launch, so angling the rails would be illegal. What we did to keep our arm from coming off the track was to put washers and pins on the ends of the falling bar that falls through vertical guides if that makes sense. S...

Re: Storm the Castle B

Can you put the guides/rails on the FAT at an angle? I don't see why not, but at the same time I don't see why you would want to. You would lose a lot of energy buy angling the rails. Add some weights or something to the other side to make it ballance out. Okay Thanks brobo! from what you told me w...

Re: Storm the Castle B

I have a few question on the event, mainly the rules: 1) Our rails are on a downward angle, so we wont accidentally fire and so we can pass the dryfire energy test. is this legal? 2) is it considered a violation of the energy rule that the arm and counterweight are on the same axle (since the center...
