  it sounds like the controller uses a potentiometer; an rctime is what you should use to get the readings your looking for.

  i tried this:
  
  ' {$STAMP BS2}
  ' {$PBASIC 2.5}
  
  time VAR Word
  
  DO
  RCTIME 15, 1, time
  DEBUG HOME, time
  LOOP
  
  but it doesn't seem to work because it still displays those weird little symbols when i try it

  i tried that and now it displays numbers but.....they only change while there moving.
  
  example: if the joystick was in the all the way down position, it would display "138" in the debug terminal, when i move the joystick to the up position in a fast movement..then numbers would get higher (139,150,160,ect.) but as soon as i stop moving the joystick the number in the debug terminal would go straight to "138".
  
  thanks,

  WAIT i fixed it. all i had to do was switch out "RCTIME" for "PULSIN" and now it works great. but can anyone figure out how to combine this knowledge with 2 HB25's.
  
  would it be like:
  
  IF 15 > 750
  THEN GOSUB forward
  IF 15 < 750
  THEN GOSUB backwards
  
  Thanks,

  Don't the HB25's take servo commands in and doesn't the futaba put servo commands out?

  I would think that what you want to do is read the pulses on two channels, the throttle channel and the steering channel. So that would require two PULSIN commands, each on a different pin with each value stored in an appropriate variable. Then, you need need two PULSOUT commands, one for each HB25.
  
  Something like;
  
  PULSIN 15, ThrottleChannelValue
  PULSIN 16, SteerChannelValue
  
  PULSOUT Left_HB25, (ThrottleChannelValue + (750 - SteerChannelValue)) MAX 1000
  PULSOUT Right_HB25, (ThrottleChannelValue - (750 - SteerChannelValue)) MIN 500
