Yes Dave I have, I thought the motor was great, The Hellfire has good off power steering, But it does push on power..I have run mine a few times and their is a lot of slop in the suspension now.. Their are a few guys that I know who have them and they have bent the shock towers..I'm not sure on the hows they did it but I do know that they did bend them. I have not crashed..real hard yet.. So I'm not sure if the support brackets are flexing or what's going on. I just think that for $600 + The Hellfire should have at least come with Metal shock caps and threaded shocks.. I know that all the machined aluminum parts cost a lot of money..Look at the price of the Kyosho ST-R.. One of the other problems I find with the Hellfire is the parts support..or more like the lack of..None of the local shops carry anything HPI, Some Savage parts but that's it..As of right now the only body that you can get that's made for the Hellfire is from HPI, No aftermarket bodies for it right now. On the local scene HPI is doing it's self no favors, I'm not the only person who is less than pleased with their "purchase".. I really did try to talk a few guys into getting a Hellfire, But I was told that parts support and track performance (as in "no shows" at the bigger races) was the reason why they did not purchase a Hellfire. I hope that your not taking this personal, It's not meant to be that. The Hellfire has held up better than my LSP..Not that that is saying much..
