Funny..the bulkhead mod was something I never had to do because I never had a problem with it an most guys I know that ran a hellfire never had any problems. Most of your other links pertain to the RTR..the SS did not really have the problems that the RTR had..I can still WIN with mine..it's not my truggy of choice..but for bashing it's fine..all you proved is that you know how to use the search feature. You are corect about HPI and their lack of suport for the hellfire..but the real problem with the hellfire is it was to stiff..no flex..so when people crashed the force had to go somewhere..the SS did address most of these areas..you can believe what you want to..I still have one so I know what's really needed.
