          28: View inside loco with both LEDs wired to the decoder
        
        
          – note the slack so that the shell can lie next to the loco
        
        
          on the foam cradle.
        
        
          Locos differ and yours will probably have different motor
        
        
          responses. The file I have posted had the motor parameters
        
        
          adjusted for the specific loco, so that it just starts about speed
        
        
          step 2 or 3 (using 128 speed steps, as I recommend). If you
        
        
          want to tweak the starting response, that is covered on my
        
        
          web site 
        
        
        
        
          ).
        
        
          
            14.0 Finish installation
          
        
        
          Just a few more steps and you will be done.
        
        
          
            14.1 Seat shell on frame
          
        
        
          Go ahead and seat the shell firmly down onto the frame.
        
        
          
            14.2 Fuel tank
          
        
        
          We’ve got the speaker in the fuel tank, but it doesn’t look
        
        
          pretty. Also, the speaker magnet will attract iron and steel
