: : : I am wondering if we blew it somewhere? I am thinking we have sufficient speed. We are concerned if we'll have sufficient traction, but addressing that with a special wheel design.

: : Glenn,

: : You're right in the sweet zone for this year's game, imho. Your drivers will be able to accurately place the bot, it will get where it's going soon enough, and you'll have good torque at the wheels for bridgework with a load. Now, about that carpet traction......

: : Good luck!

: : Dodd
: Yeah! That is going to be a good trick.
: The trick is to make it stick, but how?
: Thanks for the feedback.

We have the traction but are not sure about the ratios. We are going with 3:1 on a 9.25 wheel. We are prepared to go to 3.5 or 4 to one if needed. Available torgue will be applied to 4 wheels. We will be testing next week.
