I am going to be selling a new s/m Karpiel Disco Volante frame for a freind. I am not sure what to ask for the frame. She purchased the frame new @ $1700 and never had it built. It has a RCS titanium spring on a Vanilla RC. What do these frames sell for ? I can't seem to find any for reference. Thanx
