Let me start all this off by thanking "XIRTIC" the design of these links are all his. He has been making and selling this style of links for some time. Now xirtic guided me in how to make these links, the thing is we are not sure how they will hold up as he has never put such sharp bends in them. I'm going to be testing these and if they hold up he may be offering them up as a future option through him. After a lot of looking around and weighing the different options I like these the best. Aluminum is stong, good wieght, and decent prices, but I cannot stand how after a little use they get sticky and don't like to slide. I like titanium for obvious reasons strength, weight, and bling. Titaniums big draw back for me is price $80.00 for links just isn't in this builds budget at the moment. These links are reasonably priced, have a reasonable weight, and slide well. IMO they are a great middle of the road! They aren't the "best" in every catagory but the drawbacks are more minimal than the others. The other type is the CNC'd flat links like amny people run the thing I like about these with being round the have a smaller contact patch. Quote:

If you just slide some delrin tube over any old allthread like you would with brake line, your not going to end up with the same strength as these. I thought about using titanium allthread as well but remembering back to a painful titanium failure induced mountain bike incident in my youth, I'm not very confident that will hold up well. Titanium is crazy strong for its weight but has one big drawback. It likes to fail at a cut notch aka a thread. Now I know what your going to say and yes I know you can thread titanium but you have to do it in an area where the stress is from stretching and compression. If you bend titanium at that notch(thread) you are going to creat a point of failure. Yeah I know the lunsfords everybody seems to be using are holding up well, but if you notice nobody is bending the threaded ends! Next I bent these using a tubing bender (no not the crappy harbor freight variety). These links bend very nicely, the problem comes in when you realize you have to make another one that matches exactly. It takes a lot of time measuring, and sweat equity. I've thought about using some aluminum jacketed upper links to cut down on weight but I like how the upper links look LOL. yeah I know.. Mnster I was looking foreward to meeting you at The Collosal Fossil Challenge, and I'm quite sure we will bump into one another at a comp soon and I look foreward to it! Soo to sum up my long winded rant if your looking for links like these going foreward Message xirtic I know he would love to make you up a set. He's a great guy and fantastic to deal with. If however your looking for a bendy set your gonna have to wait to see if these hold up. Last edited by WarTrader; 11-11-2010 at 11:30 AM. | ||||

Yeah a hear you on that it seems every way possible to make links in plaqued with one problem or another. Aluminum snags on rocks but is light, delrin is either flexy or sleeved over steel and heavy. Titanium costs way to much for me to consider and not cheap to replace. Best all around and most durable is probably what you are running. So affordable and nearly cost free to replace. Yeah I've got my berg torn apart for repairs maybe I'll see you at one of the scrc comps later this year. Sucks about the fossil gorge I used to go there alot. |

im still a bit confused ... so the all thread SS goes in the delrin tubes and then you bend them? .... with a torch to soften the delrin but wont the delrin get to soft and get deforemd by the bender when you torch it at the same time??? i got these things in transit and would really appreciate if you can hook me up thanks |

I to be honest wouldn't reccomend this for somebody that isn't comfy with creating bent links already. If xirtic goes ahead and makes these he has a custom machined set up he uses that will make it a repetative process and ensure the links are exaactly the same | |

I would HIGHLY discourage using a torch for this. I have in a pinch used a mini-butane torch for some bending, but it is very easy to overheat the delrin. For my production links, I use a heat gun to soften the delrin at the bend point while it is in my link building jig. I do not heat delrin to the point that it is "dripping"....just until the dulled surface looks like it is wet. Wartrader is correct in stating the importance of the links all matching in terms of length and geometry. With the compound bends, it is very important to create a repeatable process...as it is VERY difficult to duplicate a link otherwise. My jigs are what make my process repeatable, and the links identical. I also keep a chart handy of raw material lengths so that I can easily end with the correct eye-to-eye lengths for the finished product, or easily figure out "custom length" links for special builds. It is a very flexible process. I hope that his initial testing of these links is successful. It would be great to be able to offer this strong/slick alternative. I am hoping for the best possible outcome. |

| Front Half!
This morning I started work on the front axle. I tore it down to throw in the SDS Custom 300M 3rd, the RCbro's light weight 4th, not to mention I did buy this rig used and really wanted to check everything out! Well most everything was in order sept I discovered when someboy clocked the axle they messed up on one of the holes soo I ony have two screws holding one tube in, and the drag link was delrin and was showin some serious signs of being over stressed, and the aluminum endlinks while cool were bound up. So I threw together a new link. Here are some pics of the reassembeled gear box, I didn't drill the front gears as I'm positive I will have to add wieght to the front axle. I would rather keep the weight in the axle than in the wheels.  Since I've got some major changes comming up in the very near future soo I'm not worried about fixing the messed up clocking. While I had it apart I decided to throw in the new servo a Hitec HS-7950TH. When installing it I used RC Bros Flush Mount servo clamps. When I bought the rig it came with a RCinnovations OTA steering set up which for the time being will stay put.  While everything was apart I also decided to shave the front bolt on the gearbox, and rounded things off a little. Well I'm still missing a few things to get this thing to roller status. I doubt I'll get this done today.. I've gotten a lazy Sunday afternoon planed (napping through a football game). I'll probably get to the front links tomorrow after work. Soo Stay tuned I got a idea I wanna try, but it may have to wait till the front axle 100% Done Last edited by WarTrader; 11-21-2010 at 04:32 PM. |

| Front Links
Well the Bears won and I couldn't sleep so I got out my drafting stuff and drew up some front links. I'm old school what can I say! I then threw these together.   Yes I know they look off but until the other links and shocks are bolted up nothing wil really line up and look right. To be honest I'm reconsidering the upper links. I think I may redo the upper links in the future. Maybe from Aluminum just to drop some weight? I'm waiting to see if what my final weight is. I have a number in my head that I'm gunning for.

YEAH!!!!Da BEARS!!!!! I am a fan if you can't tell. The rig is looking good. I just bought a bully roller for cheap, hoping to get it all ready for next years spring and summer crawls, again, looking forward to the Fossil challenge next year, looking to do better than this year. Staying tuned to see what happens. |

Well, if they say we can't then we will do it anyway. We are fossil gazers, i looked at them as my rig drove over them, it is not like we are damaging them, people walk on them for god sakes. And you mean to tell me that there aren't some kids trying to remove some. Oh well, I am still looking forward to next year and trying to travel to comp some more. I ranted, sorry, love the rig. |

I'm waitng for some plugs and stuff to clean the wiring up. The wiring is all soldered and ready to go. If the plugs don't make it today-tomorrow I'm going to throw them in and take it for a spin. | ||

| It's a ROLLER
Last night I made the upper links. Today I finished bolting things together. It is together enough to run just to see if the links are working right which I might add they appear to be! I still have a good bit left to get sorted out and I would like to drive it before I gotta tear the front apart for all the stuff that is going to happen there.
