No thanks...my warranty (not the controller) was toasted the first time I 
reported this trick to the list. Scared hell out of me (almost) at 15-20 mph 
going forward. I can do over a 100 in reverse - hit the direction contactors 
at that speed - oh $#@%!!!  Dualin'7 doin' cartwheels from here to Woodburn.  
Even this racer doesn't have that much insurance. Too much time and money 
spent on the car already. I did, eventually, pay for that first "power" stop. 
Just not right away. Sometimes silicon just weakens...then bites you when 
your not expecting it to.
