Does anyone have any suggestions to how they angle their propulsion system?

The best way to do it in my experience has been to attach a gun scope to the frame and point it at a marker placed on the track so it launches at a consistent angle every time.

I don't get it. Can you please explain?

You need a way to mount a gun scope to your propulsion system. After this you can look through the gun scope and move your launcher to point the scope at different objects. If you place a box or something with a line on it (this would be the marker I'm referring to) at the terminal barrier, you can point the launcher at it by looking through the scope and lining it up. This will create a certain launch angle and you can change it by moving your marker left or right. You can now calibrate your scrambler by testing out different angles.

Hi! This is my first year going to Nationals, so I have some questions.

The rules say in section 2a, sentence 4,

The backstop must be built of a single piece of rigid material (no soft, cushioning materials e.g. balsa, cork) and it must have a flat surface of 5.0+/- 0.5 cm wide by 5.0+/- 0.5 cm high by 1.27 cm (0.50") +/- 0.5 cm thick, and be rigidly attached to the ETV, and be perpendicular to the floor.

My question is, how rigid is rigid? I understand that the point of this rule is to make sure that if the egg hits the barrier, it goes "Splat!", but, technically, if the backstop moves at all, that makes the egg less likely to break. Where's the line between rigid and not? Is there an informal "standard" to test the "bendy-ness" of the backstop mount?

Sorry for the last-minute barrage of questions!

Thanks!

It has to be rigid enough that it doesn't cushion the egg if the egg hits something. They basically are saying something ridgid like most types of common wood (pine, maple) or metal. I would go with pine.
Hope that answers your question. Good luck!

Bye, Scrambler. See you in 2020.

Bye, Scrambler. See you in 2020.

The vehicle rotations have four events, so Scrambler doesn't return until 2022 (in Div C). However, you do get Gravity Vehicle, which is a pretty cool event.
