I just had to send the chassis from my new GP-7 with the QSI sound card back to Walthers because the sound card wasn't making the right sounds and would not reset. Keith from Walthers called me today and told me the sound card was bad so they were sending me a new chassis - thanks, Keith and Walthers. My question is the headlight behavior. The headlight on the short hood goes dark in neutral while the headlight on the long hood stays on and dim. Keith said this was normal for long hood forward operation and, sure enough, there is a microscopic "F" on the long hood. As far as I know, the UP never routinely ran their GP-7's long hood forward and didn't have the long hood designated as front. Keith tells me the production team at Walthers is very careful to only get the right prototype with long hood first headlights. Have I lost my mind or is Walthers right about this? If you buy one of these, make sure to check what end is designated as front on the model as this will determine how your headlight behaves.
