thanks in advance
The Stinger PID settings are identical, as they use the same motors. However, the physical dimensions are different, and you'll need to take that into consideration for things like TicksPerRevolution (of wheel), Wheel Circumference, and Track Circumference (for rotating).
If you look at the SerializerLibMF documentation, we have the exact physical specs for the Traxster and Stinger under 'Namespace RoboticsConnection.SerializerLibMF->StingerConfiguration and ->TraxsterConfiguration.
