It was recently reported by a number of roboteers that when changing from 40mhz control to the 2.4ghz Spektrum, their robot appeared slower, or less powerful.

If you feel this might apply to your robot, you can try the 3 things below, and it should cure the sluggish tendency completely.

1... re-calibrate your sidewinder to the new controller. This is easily done, you can get the instructions on how to do this here

This has been found in the past, to cure 99% of all reported problems, and it is surprising how recalibration can keep your robot in peak condition. It is recommended you do this if changing radio controllers for sure, as there can be big differences, but also on the first morning of every event, as it sets your robot up to the specific atmospheric conditions on that day, maximizing the controller setup for maximum performance. It is a small tweek, but in competition, everything gained is a plus.

2.... check you current limter is set correctly. Having it set too low makes your robot seem heavy and slugish. Be careful not to set too high though, or to switch off completely.

3..... check your slew setting. This is your acceleration ramp adjustment, and setting it too low makes your robot seem heavy and sluggish. Adjust to your personal driving preference.

Please keep all your feedback coming, email me with any information, technical observations, or problems, to ensure we keep the sidewinder at the top of the robot speed controller range.
