I miss my Serpents, been to the fuel nationals back in 1999 or 2000. When it was held in New Hampshire. My RS4 was my only HPI but I still had my Impact and Vector with me. Engines have been Picco's. If I was still racing competitively I would probably still have my Serpents and would have sold my HPI awhile ago but life got in the way. If I were still in NY I'm sure the hobby shops I used to deal with would have them and parts for them in stock since they all raced them.
