Regarding reduced steering throw on the MA-030EVO after resetting parameters with I.C.S. Manager Ver 1.2:

Incorrect steering end point value was set after pressing "Display Reset" button of I.C.S. manager Ver 1.2, and that caused reduced steering throw on the MA-030EVO chassis.
I.C.S Manager Ver. 1.3 is now avaialble for download, which allows you to choose a chassis type upon resetting parameters.
