Well............if it could be a onroad chassis then i HONESTLY think its a RS4 NITRO RACER CHASSIS (not the famous racer 2).............the chassis looks exactly like it and the holes looks like theyed line up............im compareing mine to urs in the pic as we speak and it looks 99% the same............but there is 2 or 3 holes missing on your chassis that has me douting its a RS4........


this is the chassis from a RS4 racer 2



urs look to be from a RS4 nitro racer 1..............compare see if i hit the nail on the head!!!!
