- At our Regionals, we used the ballistic nylon that we have used in previous years from Rocky Woods. At Championships, we switched to a thicker Sail Cloth much like 254 uses.

Thanks for the quick answers! Here's a small follow-up to the above answers.
- I know you had to use saftey wire to prevent the wheels from delaminating. Around what rpm do they start to expand?
- Where did you buy the Nylon? We tried the robopromo material while another local team used the andymark nylon and we both found it to rip very easily.
Congrats on your successful season. Your robot has a lot of care taken in the little details, your constant Einstein appearances aren't a coincidence!
