Do mean that they're like, rotated 45 degrees to one direction? If that's what you mean, it's because some tension boomilevers don't have space to fit the 5 cm by 5 cm loading block "regularly". Thus, they rotate the loading block so it can still rest on the boomilever.

Does that make sense?
If the loading block doesn't touch the corner, the resting place will be slightly weaker. I suspect the 45 degree tilt is so that the tension members can extend closer to the actual position of the load (center of the block) without running into the sides of the block, and still keeping the boomilever width small.
What he said :D ^

Do you guys have any tips for me? I'm pretty inexperienced with tech events so it came as a shock to me when I got two.
Anyways, I'm mostly worried about Boomilever. Any tips and tricks you guys have is appreciated! :)

1. Always start with a heavy boom to get construction concepts down.
2. Always overbuild your base.
3. Use good wood!

Use very little glue. A common temptation (I speak from personal experience) is to use a large drop for every joint. Don't do this! A small glue applicator, made by twisting thin wires and attaching to a stick of balsa, will be crucial to maintaining a low weight. Also, a jig or prop will greatly aid in construction. Thirdly, make your joints as tight as possible. While this may be obvious, I have seen teams with noticeable gaps in their joints.

Hope this helps

Build as many booms as possible... build at least 1 every 2 weeks...

I’d even shoot for 1 or 2 a week if you’re really looking to make progress. And make sure that you’re modifying your design in stages. For example, if you had a compression failure, you shouldn’t strengthen your compression members and lighten up on your tensions because then you may get a tension failure and have to retest that compression modification.

Also slow mo all the testing and go frame by frame to see the exact point of failure
