I bought some about a month ago,, found it on ebay,, came in a boxed set, a red and blue one,,,,,, on the box it says "yamaha licensed product", made by ertl,, they are 1/18th scale,,, it also says to search their website,,(www.rcertl.com),,,, it also gives the stock no.12689/36914E---Hope this helps,,,,, by the way,,, on the box it also says "ATV'S can be hazardous to operate, the raptor 660 and grizzly are recommended for use only by riders age 16 and older",,,,, guess you cant be too careful..... ..... .... cg
