In the other Lindberg tug thread, we've discussed a number of classic Lindberg ship kits.
Lindberg released a generic tug in a box called "Coast Guard Tug", which is pure fiction. It is ironic, as the larger Diesel tug kit is a model of a class of tugs that saw at least a few in USCG service.
Here's my tug, built as the USCGC Messenger. Conversion was pretty simple- I just sanded the molded in "S" off th estack, and added a USCG paint scheme.
Model is shown here with Eric Bertelsen's 7 foot long Illustrious -class carrier. My tug is two channel RC, has enough power to slowly turn the big carrier around..
