ORIGINAL: j-boy

OK so I went through the whole steering system and this is what I came up with. I started with the steering knuckles and hubs. I ground a little clearence off of each side of the hubs and a little off of the outer front of the steering knuckle. I kept noticing that my servo would only travel a short distance when turning left. I was messing with my Nomadio React trying to get more travel out of the steering servo and finally noticed what was stopping it. The linkage coming from the servo saver actually hits the upper deck. I turned the screw and nut upside down but it still hit so I actually ground some clearence into the upper deck. I also ground some clearence into the front servo mount and removed the rubber grometts from the servo to let the servo set back a little farther inside the chassis. I'm not so sure that last step was nesasary though because after I got everything ground out I discovered that the final limitation to steering travel was the wheels hitting the steering arm links. The pics below are poor quality but they are the best I can do with my crappy gigital cam. The pics are all of places that I grinded clearence except for the pic of the wheel. That picture is just there to show that once you get to the point where the inside rim of the wheel is rubbing the steering linkage you have gone as far as you can. I wish I could say that I've tested these mods but it won't quit raining here [&o]. I am pretty confident though that I've gained quite a bit of steering. I did all of the grinding with a dremel using a small sanding drum for the plastic and a stone grinder for the upper plate. As allways you should know that I'm still pretty much a newb and you should take this advice at your own risk!! But if you decide to try this out, good luck and take your time. If anybody's got questions, post them and I'll help or explain better. Post u later I guess if I had it to do over again I would start with the upper deck clearence. I am pretty sure that was causing the limited travel when turning left. Doesn't say much for HPI enginuity but I still love my Hellfire
Nice finds.. Can you make the pictures a little bigger though?
