Only place I could think to post this
 

I found
http://cgi.ebay.com/O-S-NSU-Wankel-3...QQcmdZViewItem
that on ebay earlier.
I'm thinking about buying just to have one, i will give it to my brother for his Gas RC car. Pretty cool

that looks pretty sweet. a kind found one in class one day. and "bought it from his teacher" there was a thread on it somewhere in this other rotary section. not sure what he said he was gonna do with it. but it would be fun to mess with.

Build a wankel powered replica of your car, and then put that on the dash of your car :)

I don't know, I think its pretty cool and will probably pick it up.

I had one of the frist ones back in the early 70s, the one in the pic is a 2nd gen has no cooling ring, the frist models had a over heating problem so a add on ring with more cooling fins was added, I use to fly RCs, they are a .3 cid and had the power of a .4 cid piston and ran much better in all the power ranges
