--- The Crawler Innovations XR-10 Build -- I am notorious for dragging my feet on things. This XR-10 build has been no different. It's not so much that I'm a procrastinator, it's just that new designs always have flaws and with the durability our bergs have given us, I had no desire to move to an XR-10. Crawler Innovations became a dealer for Axial through one of our other distributors so I purchased an XR-10 kit back in June. I gave the kit to my 9 year old son Gavin about two weeks after school got out for the summer. I showed him all the parts I had slowly collected for the this truck and gave him the option to build it box stock and sell it as a roller for the store and I would pay him for his labor. Or... he could build the truck for himself and it would be his new comp truck assuming he liked it of course. Well Gavin decided to keep it from the beginning. So he only assembled the axles from the kit. I had purchased a Y Town Crawlers, Carbon Fiber, V4 Beetle Juice from Jeremy back in April in Alabama at the East Coast Championship. So once Gavin assembled the axles, I began setting up the chassis and links. At first I used the Crawler Innovations delrin lower links. I used black low clearance delrin links in the front and black REAR high clearance delrin links in the rear. It was set up in a 60/40 configuration. It was OK, but I did not like how my titanium upper links turned out looks wise. Being a newb with the XR-10, I also was unsure what direction to actually go with the truck. Do I use front axle cases for both the front and rear? Should I modify the rear lower links to mount to the rear shock mount? Is 60/40 best for this truck? Etc, etc, etc... I tend to over think things:roll:. So... I scrapped the first set up and went for a K.I.S.S. (Keep It Simple Stupid) set up. I ordered titanium upper & lower links from Chaotic Crawlers along with there Ti steering link for VP Knuckles. I used 3.5 Traxxas shocks in the front and 4.0 Traxxas shocks in the rear. I also kept the axles and mounting positions as designed. Slowly the truck came together, but it's taken three months to get it running. Mostly from me being busy running the business and partly from a lack of interest. With the historic heat wave Texas is having this summer, it's been to hot to work in the shop and too hot to go out and crawl. We have finally had some nice weather this last week. I took advantage of the Labor Day holiday and finished this truck. We have the ETXRCC season opener competition this Saturday and we will see how this trucks performs on the rocks in competition.

My original wantasummit mix was glitching and I was never happy with it on my berg. I was also not excited about the super long leads and added weight. He came up with a new firmware and a new design8). So we tested it and it was definitely an improvement over the original design. On this XR-10, the unit performs flawless."thumbsup" The unit on my berg is still having occasional issues, but I think I have narrowed it down to the DX3R. So the DX3R will be going in for repair soon.

Looking great Eddie! Tell Gavin he did an awesome job! You must be a mind reader because I was going to email you about your delrin links and the BJ4 chassis. LOL!!! |
looks nice man, i like the way the chassis doesnt have that leaned back look that a lot of the bj trucks have. no khaos tires?"thumbsup" |

Thank you and he will read this when he gets home from school this afternoon. He loves this truck. The only simple comparison I can make is that it's like driving a Cadillac. It's so smooth and works so well. Gavin and I are both shocked at how well it is doing as is. We have not invested a lot of time in tuning the truck. It has 5 battery packs through it total now. Gavin and I play follow the leader, he drives the XR-10 and I drive the berg and both trucks are just amazing. But the berg drives and feels more robust and heavy duty, where as the XR-10 drives smoother. I'm saying one is better than another, but I am excited to see how the XR holds up. As for the delrin links, I prefer delrin lower links and titanium upper links. I think delrin links slide better on the rocks. The delrin lowers on my berg have two years on them now and they are smooth with the rod end on bottom from all the drive time on them. The XR-10 axle design and the V4 chassis design were different link wise. I had to reform the REAR High Clearance links with a heat gun in order to curve from them chassis out to the rear axle link mount. The V4 is a very skinny chassis and the XR-10 rear link mount is pretty wide on the axle. The front low clearance links were not a problem. Of course I want to sell my products, but I am not 100% sure what is best and easiest for the customer at the moment. I don't have a lot of time myself lately, so I purchased the Chaotic Crawler links. Chaotic's service and products have been excellent. If you prefer to run delrin lower links, let me know for certain and we can set something up. |

Thank you.8) Like I said earlier, this truck has little time on it. It just got running late Monday afternoon. As for the Khaos tires, we have been running Blocks mostly and testing new proto types. We started with this Sedona set up because it is what Gavin drove at Nationals last year and finished 52nd at only 8 years old:mrgreen:. We have also loaned this set up out to other drivers at big comps. So we were looking to create a baseline to begin testing from with a set up we are very familiar with. I will post pictures and videos of some of the other items were have been testing when the time is right and the items have been proven. |

hi this is a nice truck8) and cool to give us all this info "thumbsup" I'm interested too for the delrin link, I have some High clearance link for the rear but this not as smooth as I want :) |
Very nice Eddie, looks sweet. Gavin should have a blast with it"thumbsup" Later, Farmer |
very nice. that is going to be slicker then snot on a door knob. |
That is a good looking XR he has there!!! I love the stance! I think he will really like the truck! Once you get past the breakage prone parts, the axles seem to drive alot smoother than other axles out there. We appreciate your support of us, and the compliments you've given!!! I'm interested to hear how you like that foam combo in the truck. I've been thinking about trying sedonas again. "thumbsup" |
HAHA Can I be your kid? :D That's one nice crawler! I'm sure Galvin will love it! |

The combo in these sedonas are proven. Scattman ran them at the East Coast Championship this year and had never run them before. He needed something for his truck and borrowed what he wanted to run from me and used them the entire comp. He liked them:ror:. Quote:

Delrin is still a form of plastic and can only handle so much. Plus my links are pretty thin and light weight so you have the added risk of link failure. I am aware of a few link failures and those links have been warrantied. But overall, the delrin links have held up well. Thank you for using Crawler Innovations brand products"thumbsup" |
Great looking build. 52nd and only 8? Thats awesome"thumbsup" My boy is only 3 but he loves to watch me work on and play with the Crawlers. I can't wait til he can join me with a crawler of his own. -Trent |
Eddie, that's a great story, it was very enjoyable to read and Gavin has put together a great looking XR. I'm sure he'll put it to good use and soon be showing lots of us how it's supposed to be done. It's got a strong backbone of great options and I'm betting this thing has got some staying power. Gavin's going to give this one a good work out on those new crawling areas out your back so we'll soon see. Nice work by both of you. 8) Delrin is a great way to go, it absorbs shocks much better than rigid links IMO, I like the way it feels when driven. My uppers and lowers are both Delrin and they are strong and light and no problems. "thumbsup" |

Thank you so much Norm"thumbsup". |
ETXRCC (East Texas RC Crawlers) had our season opening competition yesterday. Gavin won first place using this truck. It definitely needs more drive time and tuning, but obviously it worked well enough to win, so that was really neat. The courses were pretty hard. Gavin was the only driver to complete course 3 and that was the difference between 1st and 2nd. We didn't take any video or pictures unfortunately. We ended up running Red Blocks for the competition instead of the Sedonas. We also had to widen up the track width front and rear. The courses had a number of off - camber challenges and a few tough break overs. This truck is off to a good start and I will post up the changes we make to the truck as the season moves forward. |
That awesome Eddie! Gavin, good driving and keep up the good work! I know everytime I hang get hang out with you I learn something new. Can't wait hang out with you guys on the Oct 8th! "thumbsup":mrgreen: |

I will let him know Eric. We are going to have a great time on the 8th. We will be cutting down a huge dead pine tree in two weeks and incorporating it into the G6 course for the 8th. For those that don't know, Crawler Innovations will be hosting this G6 cash comp and USRCCA ETXRCC Season comp #2 on October 8th: http://www.rccrawler.com/forum/texas/334473-%2A-%2A-%2A-crawler-innovations-g6-cash-comp-october-8th-2011-%2A-%2A-%2A.html |
So what size hubs did you run? |

Memory Outer foams |
Great looking rig Eddie! How are you liking the wideners with the Blocks? I really want to make me a set of the red blocks after trying Itty's. He is running them on 1" rims and they are working very well. I like the extra clearance you get along with the smoothness of a pin tire. Great work!"thumbsup" |

Thank you. I really like the wideners and wider wheels. I am only using a 1" wheel with Rovers currently and I have been testing with 1.25" wide rovers again. I am also going to start modifying and testing the pink dot rover. I think there is a lot of possibilities from that tire that have not been explored. |
Watching this thread. Lovethe rig. Makes me excited to get mine done |
We have been testing new tires with this truck: I have been thinking about this tire for a while and finally just made it. It's a HB white dot Sedona with a HB red dot Block. The sedona has been narrowed a 1/4 inch and the block has been narrowed about 1/8. These are early pictures. I have not mounted them up yet. The Block tired actualy had to be reduced to line up properly with the narrowed sedona. It takes three tires to make one tire. http://farm7.static.flickr.com/6153/...5562d955_b.jpg http://farm7.static.flickr.com/6160/...7e8e604c_b.jpg The Sedona side of the tire inside out: http://farm7.static.flickr.com/6161/...c1f76fc3_b.jpg The Block side of the tire inside out. The block tire had to be belt sanded before it was cut. http://farm7.static.flickr.com/6164/...2a0440c1_b.jpg Mounted on the XR-10: http://farm7.static.flickr.com/6124/...6f1d7d2a_b.jpg http://farm7.static.flickr.com/6175/...5c69e0b4_b.jpg http://farm7.static.flickr.com/6163/...7a60fb14_b.jpg Specs: 6.0 RTR weight Custom 1" width VP DH1 wheels in front Proto type foams I mounted these up and my son ran them unmodified. He said" they do easy things hard and hard things easily". So the next day I went out and tested and pretty much confirmed what he said. We have one obstacle that we have practicing on for months now. It's the type of obstacle where you can attempt it 20 times and if you were lucky you would complete it once. So I tried this obstacle last. On the third attempt it made it. Then it made it again. After that it struggled a few times and then it made it again. It was clear that the full pin pattern was too crowded. So I went ahead and cut a pattern into the pin side of the tire and went back to the same obstacle. It cleared the obstacle 8 times in 14 attempts. So I am clearly on to something now. I just wanted to update the thread. |
Three tires to make 1? I would hate to think how much a set of these is going to cost. There must be something in the water, cause I thought 6" sedonas were crazy.. What next? These look great. Am keeping my eye on this thread for sure. I like the idea of a pin tire and the sedona. I would have switched them around though and put the sedona tread on the outside. I like to run Sedonas in the front and Rovers in the rear of my rigs, has worked good so far. This makes me wonder about half rover and half sedona tires. Keep up the good work. |

Welcome. How does the width compare to a standard Sedona? I am having issues with the tires cogging, because the inside lugs rub on my servo and other assorted bits. I don't want to sand down the inside lugs, because I like to turn the tires around and get even wear on the lugs. The side lugs do help, so I don't want to loose them or loose the ability to rotate. With the smooth side wall of the pin tire, that would fix my cogging issues, but am wondering about the width. I like wide tires for the additional footprint.. Can't get too much traction.. |

So I definitely use and recommend 1.25 & 1.35 wheels. That said though, I have encountered a few times where my red blocks had no forward bite. So that is one reason I created this tire. I only made one pair of the tires pictured. I just made a second pair for the rear this morning. They are wider than the first pair, but still narrower than a stock width sedona or block. Quote:

That is why I am using a proto type set of VP DH1's I have. These wheels were narrowed from the back side and were a proto type VP made for testing of the DH2 machining. So these wheels are nearly flush at the back even with a 335 hub. |
I like the setup man, looks good! By the way I am loving the 6" sedonas. They work awesome up here in michigan, thanks!"thumbsup" |
Oh man those tires are sweet!!!! Just what I need! |

Just kidding and thanks8) |
Lovin all the testing Eddy. I always liked my sedonas because of the large lugs with good spacing but like you said when big lugs bit they hold on. I find some times the lug can be a bit big to really conform well so these could be a wicked tire. |

6" ??? This rig looks great and would love to see it run.. |
This is a very clean looking rig - great job!!!!! |
Tires are looking awesome. I have always liked the Sedonas, but now that I'm running the Khaos Pins they are my new favorite for sure. For the most part they crawl circles around the Sedonas but there are those few occassins where the Sedonas just seem to work better. Now a tire with the best of both worlds. I am definitely interested. |

Couldn't said it better my self i run my blocks but there is this one course that we run that the sedonas just seem to work. Great job eddie your changing the way we all crawl with your great tire ideas. |
