anyone used the wild thumper controller?

hi guys and gals , as the subject line suggests..

anyone used the wild thumper controller? more specifically im trying to map i/o pins in relation to the romeo mcu.. whilst utilizing the standard example code for motor control..

void advance(char a,char b)          //Move forward
{
  analogWrite (E1,a);      //PWM Speed Control
  digitalWrite(M1,HIGH);   
  analogWrite (E2,b);   
  digitalWrite(M2,HIGH);
} 

////////////
Romeo...
/////int E1 = 5;    //M1 Speed Control
/////int E2 = 6;    //M2 Speed Control
/////int M1 = 4;    //M1 Direction Control
/////int M2 = 7;    //M1 Direction Control-


wild thumper....
//#define LmotorA            3  // Left  motor H bridge, input A
//#define LmotorB            11  // Left  motor H bridge, input B
//#define RmotorA            5  // Right motor H bridge, input A
//#define RmotorB            6  // Right motor H bridge, input B

E1 is speed control for M1.....soo in relation ...is E1, LmotorA or LmotorB??

for example can i cheat and do

int E1 = LmotorA  ;    //M1 Speed Control
int M1 =  LmotorB;    //M1 Direction Control
int E2 = RmotorA ;    //M2 Speed Control
int M2 = RmotorB;    //M1 Direction Control--..

thanks in advance if anyone understands what im trying to do and can offer any help..
