Re: Trajectory B/C
Oh yeah, sorry, it's a magnetic release. Otherwise I would be Tier 2-ed in a second.
The diameter of the magnet is about 2" or 1.5", there are picture of it on the website. Although they are before I made a change to the design.
All of it fits nicely under the 60 cm cube by an inch or two on one side, on the top, and way clears the width.

Re: Trajectory B/C
my catapult has so much force behind it that when using a pin it pulls the whole catapult with it
any ideas for another release mechanism?

Re: Trajectory B/C
You stick some thing with a hole in it on what ever is firing the ball and you latch the gate into that whole then pull back the latch to release.NIXINATOR wrote:How does that work?

Or you could use a bow release. That is what i use and it works very nicely.starpug wrote:You stick some thing with a hole in it on what ever is firing the ball and you latch the gate into that whole then pull back the latch to release.NIXINATOR wrote:How does that work?

How would a one cm margin of error stand up at nationals?

Re: Trajectory B/C
That's really good. If you aim for the center of the target with a 1cm margin of error, you can almost certainly still hit the pin if you're firing a tennis ball. So unless Nationals uses a different method for marking the center of the target (like the 2 diagonal strings that make an "X"), you'd get basically a perfect score- assuming no penalties or anything.

One cm is amazing. Are you getting that at all distances/heights?sj wrote:How would a one cm margin of error stand up at nationals?
