I think MTH must be reading this forum, I just checked their shipping schedule and new dates have been input. My engines are now shown as a March delivery, just yesterday when I made the post it still said January.
My wait will soon be over, hopefully this new date will be the last change required to the schedule.
I really like their products. Nice to know they may have been listening (it could of just been a coincedence, but I will give them the benifit of the doubt!)
