Help with gear ratios

[daveimi]

Thanks for the help as always, Rory you've done that before!! And thanks for the info on the Calculator, knew I'd seen it one of the sites.

20:1 is higher than I was expecting but it would be easy enough I suppose with a two stage reduction. Something like 5:1 then 4:1 to the output shaft.

Glad you liked that one Terry, I hear you are building a new robot.
I'm looking forward to your next creation don't forget to put up a build thread.

OK targets to aim for if you want to build a Heavyweight.
1/ Get the robot through the first Tech Check.
2/ Drive robot into the arena without it breaking.
3/ after 3 minutes drive robot out of the arena (this one can take a few attempts!)
4/ get the robot to fight in all the shows that weekend.
5/ your first fluke win,
6/ congrats you've got as far as me after
7 years.
