use a case structure that divides by 2 when <50 and doesnt do anything when its >50 so when joystick value is <50 power output is cut in half
and when >50 output is normal this is what we are using for our logitech controller
it will be something like
10=5
25=12.5
50=25
75=75
100=100
you can adjust the parameters of the case by adjusting the separator
hope this helps
