[FTC]: Tips for Teams going to the Vex Championships

The problem typically does not reveal itself in the pit, since the drive motors aren't under the same load as when they are pushing bots on the field. At least one bot with this problem would stop and restart during the match and appeared to be running without operator control.

This is a new one on me. I've never heard of it before. We competed at three regional championships and this did not happened to our team before. But it did happen several times at World's. How can you avoid it?

We ran into this last year when we had a bad controller that would not even deliver 4 amps. We called IFI and they explain the following about the draw of 4 amps. Now we always are careful not to run to many motors under load and we also change out every match with a FULLY charged battery to help the amp drop problem.
