| 3 Link or 4 Link
OK, total newbie here at the RC thing. I just picked up a 1.9 Wraith and a Builder Kit yesterday morning. I noticed when I got the Wraith home that it was only 3 linked on the front which I thought was in error as it is clearly designed for a 4 link front, but then when I started the builder kit, I saw that their instructions were to 3 link the front on that as well. So here is my question, do you guys 3 link or 4 link the fronts ( I get that the 3 link should give more articulation, but I also notice it leans and torques real hard to the side without the link). Second question, how about the rear, if we are only 3 linking the front, why not 3 link the rear? Again, total newb at this and trying to learn ( I do rock crawl a jeep I built - 4 linked all around) but the RC thing is a bit different and looking for your guys knowledge and feedback. Thanks in advance. Randy Last edited by Texas_Jester; 05-12-2019 at 04:22 PM. |

3 link is used almost exclusively when the steering servo is chassis mounted (CMS) rather than being mounted on the axle. 4 link is pretty much standard for axle mounted servos. The reason for the 3 link with CMS is you need a panhard bar locking the side to side movement of the axle to reduce/eliminate bump steer caused by the suspension articulation. If you were to use a 4 link and panhard bar you would restrict suspension articulation to almost nothing. Used to be CMS was an upgrade either from the OEM or from the aftermarket. Seems now everyone is jumping on the bandwagon and many of the manufacturers are offering it as standard, Axial Wraith 1.9, Axial SCX10.2, Vaterra Ascender, Redcat Gen8, etc. Stick with the 4 link on the rear. |

I have a first gen SCX-10 that I want to upgrade to CMS. Do I maintain the 3-link because of the upgrade? I was planning to upgrade the front to 4-link also Sent from my iPhone using Tapatalk Pro | |

So to convert your SCX10.1 to CMS, you probably want to do the true 4-link upgrade to both the front and rear and then remove the 1 front upper link. Check out the Axial website for a manual for the SCX10.2 to get an idea of how they do the CMS on the SCX10.2. Its rare to see anyone running the 3-link setup you have as most have upgraded to the true 4-link setup. | |
