You are bidding on a bunch of old 1980's era radio controlled electric 4wd buggy parts.  There are no electronics included.  You really have to look at the photos and what you see is what you get.  Most of the parts and almost a complete chassis are from a Kyosho Rocky 4WD. There is also a Kyosho Optima 4WD that appears to be mostly there as well.  These are obviously used except for the parts you see in the bags yet.  It also appears that the front and rear A arms on the Rocky chassis are new or barely used. These were part of a collection we acquired and were in a box by themselves and so that is all I really know about them. Let me know if you have any questions and thanks for looking.
