In case you are unaware; it is fairly likely that bernard built the device pictured.

Thank You

But I still need to know where to get the best wheels for scrambler?

Actobotics and BaneBots are popular choices. Note that both require hubs for attachment to shafts.

What do you do to align the wheels on the axle so they don't wobble?

If you use Actobotics or BaneBots wheels, they sell a variety of hub sizes for your shafts.

What is the best width of rubber for the string propulsion system and how many Newtons should the force be? Also, how many time do you loop the rubber band around, such a 2 times around, 4 times around, 1 time around (how many strands of rubber bands used). P.S I am very bad at explaining as you can tell. xD :|

Here is a picture to help what I am trying to say.

Width, length, and number of loops depends on your desired spring constant and amount of stretch needed. More loops and thicker rubber create a higher spring constant, while a longer band can potentially stretch a longer distance. The rubber I used is Tan Super Sport (your team members doing Wright Stuff should have some) and length and width were determined by experimenting and making appropriate adjustments.

What has the length of rubber you used and what thickness?

The width I used was either 0.081" or 0.087" and the picture looks like either 2 or 3 loops for a length of approximately 9" when mounted on the launcher. Different length and width combinations can be used. No fancy science was used to decide my length, just trial and adjustment.

How long was your total rubber band and how did you archery release work? Also, what is this paper called? https://github.com/scioly/scioly/blob/g ... vice/5.jpg
