Go to Post By "resources" do you mean money (sponsor or school), school support or permission, build facilities, or mentors? All of these require different solutions. - Carol [more]

Again, what colors are the LEDs of the Jaguars in question?

The symptoms you describe sound like you need to implement ramping. The reason is that a sudden start or change in direction induces a current spike well above 40A to overcome the moment of inertia, which trips the Jaguars' over current protection. Ramping will allow you to avoid this current spike and thereby avoid tripping said protection.

Refer to this thread to see some details on how to do this.
