BTW, does anybody think that anything else needs to be added to the first few posts?? Is it missing anything? Is anything incorrect? |

Something like this: http://i498.photobucket.com/albums/r.../caster001.jpg EDIT: I'm talking about the picture of your Super. The picture of the Wraith looks good, but would also benefit from a vertical line so people know what your are measuring off of. |
Re: RC Crawler Steering Thanks for the input. I will work on a new picture this evening. Thanks! "thumbsup" |

The same applies for vp's axial knucks as well.. only problem is those are reverse acherman knuckles. Meaning outside turns sharper than inside. For correct steering path we need the inner tire to turn sharper so they acually made them 15* in the wrong direction...the green lines on ur diamgram need to continue all the way to tierod mounting point. Whick will show were they are "supposed" to mount for correct acherman. only problem is that when you go past 0 and even 0 acherman knuckles the tend to rub the inside of the tires pretty bad. At least with the ax style high steer knuckles from what I have found. Those do work for correct acherman tho when applied in BTA steering setup. Jeremy this is a very insightful and informative thread. Big ups to you bro |

So, for a "correct ackermann" setup, these VP knuckles need to be run behind the axle. |

Re: RC Crawler Steering Quote:
As I stated before, you are covering things that need to be covered. I'm only "pissed" I didn't beat you to it.;-) Again, great job.8) |
Re: RC Crawler Steering Remember this "tech article" about getting more power out of your steering. Not as informative as this thread but still a good one. "thumbsup" RCCrawler.com- Your #1 source for Radio Controlled Rockcrawling! |
Re: RC Crawler Steering Yeah... Stickie this thread . . "thumbsup" Sean . .. |
Re: RC Crawler Steering Yeah, I browsed through several of the tech articles before I wrote up the first few posts in this thread. I wanted to get a good format and I wanted to make sure it hadnt been covered before. BTW, this info will soon be a tech article on the main page. "thumbsup" I just wanted to finalize a few things before Jason posted it. |
Re: RC Crawler Steering Quote:
Well done to you for all your hard work with lots of great infomation.... |
Re: RC Crawler Steering 1 Attachment(s) post #84 nailed ackerman. I can't beleive that the only crawler that comes from the factory with a correct acerman set up is the xr-10. All others are not even zero. They are going the wrong direction. When would it ever be a good Idea for the inside wheel to not turn as sharp as the outside wheel. Check out the almost corrected bully ackerman. |
Re: RC Crawler Steering Quote:
http://www.rctek.com/technical/handl...ple_radius.png Zero ackerman is when both the inside and outside wheel turn the same amount. Reverse ackerman is when the outside wheel turns more than the inside wheel. |

Re: RC Crawler Steering yep"thumbsup" |
Re: RC Crawler Steering This is crazy talk, everything is as described above. <s>I will go flip my knuckles around if I need to, but I'm 99% sure the ackerman knuckles sold by VP and axial are correct ackerman when mounted in front of the axle and are reverse ackerman when BTA. It's pretty much something I think about every day. You need to run assloads of toe out to achieve reverse ackerman when using ackerman knuckles in a (can i say FAS?) front axle steering setup. You only need a squintch of toe in to achieve the same amount of reverse ackerman when running the same knuckles BTA. Can anyone else corroborate that?</s> |
