Whats up bud?. Wow haven't seen a hpi twin in yrs.. NICE!!! Or even any of the twins that were made. HPI, OFNA,and KYOSHO... First thing that fuel tank with the primer is going to give you problems prone for air leaks. You can go with a twin fuel cell mod. Or a big single tank off a plane. Is that tranns got 3speed or just the two speed? I got some video on the twin you can watch about the set ups. You also got to get the carb linkage to be persist so the open at the same time. That's is very important they can't be off at all. Better to link them together.. and I would say get the roto start for them. I'm all about a pull start. But with the twin. It would be easier for you to start. Cuz you won't kill your self trying to pull start them both. Here's some videos you can watch. And get some ideas from them. I believe that chassis was a aftermarket one designed over seas for the twin. Some people actually were cutting there chassis up to do this mod back in the day.... so cool can't wait to see her back in her glory and screaming in some dirt...



need anything just post up and ask bud
