1.9 Wild Worm Scaler So I haven't built a scaler in a while (nor posted) and I figure it was time to do something different since my dad and I got back in to comp crawling. The original plan was to compete in C2 and just build the same old same old. But being competitive I wanted to do something that (I think) would give me an edge. Enter worm drive axles. And I know what you're gonna say: 1. They are slow 2. They get hot 3. They need lots of maintenance But! I live in Florida so all of crawling courses are short and man made so they are better suited for tvp setups. So after doing the measurements I get a few benefits that I think will prove well on it's first comp. 1. About a .25" more clearance than a stock Scx10.2 2. Built in drag brake 3. Lower LCG with smaller trans So heres what I got: - Losi night crawler axles - LNC esc (supposedly waterproof) - LNC Transmission - Scx10.2 Frame and temporary trans - Assorted custom links - Four piece aluminum beadlocks - Disc brake weights - Scale internal spring shocks (20wt oil) - Steal shafts - 25kg metal gear servo - Duratrax deep woods all around - Other misc scale stuff, ladders, winch bumpers, etc. The end goal is to do an old school f150 halfcab hardbody but for now its a shorter wheel base so I could fit my titan body on it. |
Re: 1.9 Wild Worm Scaler Interesting, ill be watching. |

Re: 1.9 Wild Worm Scaler Nice Work Red Ronin! Where did you get the older Titan body from? Let me know how well you do at the comp. |

Re: 1.9 Wild Worm Scaler I'll have to get some photos of the axles in better light but here is a pick of the clearance I'm getting now. Maybe I can mod them to fit some KYX portals? https://i110.photobucket.com/albums/...o06/123_1.jpeg |
Re: 1.9 Wild Worm Scaler Wow, not bad on the axle clearance considering they're not portals. Nice wheels with the Deep Woods tires."thumbsup" |

Re: 1.9 Wild Worm Scaler Little update. I’ve been using the the axial transmission with a 28t but it’s still a tab bit too slow. Eventually I will going with a 2 speed transfer case with a direct drive. But for now I’ve been putting my 3D printer to work make a skid plate that takes the LNC transmission. https://uploads.tapatalk-cdn.com/201...a9c3cbafc7.jpg Sent from my iPhone using Tapatalk |
Re: 1.9 Wild Worm Scaler So I decided to do something more different. I figured I could mount the LNC tranny sideways up front and then order a transfer case. I designed a mount that wraps around the Losi tranny so the motor can ride up top. That way I can also make the bottom of the mount look like the bottom of an engine. For now I’ll test the vanilla mount. As soon as I know it’s good I can post it to shapeways Incase anyone wants one too. https://uploads.tapatalk-cdn.com/201...e1ce2a3e55.jpghttps://uploads.tapatalk-cdn.com/201...58ad1f1b49.jpg Sent from my iPhone using Tapatalk |
Re: 1.9 Wild Worm Scaler Digging this always toyed with the same idea, picked up a Chinese 1:.75 ratio transfer case just for a little wheel speed boost but it's so wide it'll need trimmed and re tapped just to fit decent between some frame rails. Sent from my SM-G930V using Tapatalk |
Re: 1.9 Wild Worm Scaler Quote:
Which transfer case is that? I’ve seen the two speed one on eBay for about $50. Sent from my iPhone using Tapatalk |
Re: 1.9 Wild Worm Scaler One of our local guys runs them in his class 1 and 2 comp rigs. He usually does very well. The 2 years that I competed, he got 1st place in C2. I think he is running an original LCC trans with a high kv brushless setup. |

Re: 1.9 Wild Worm Scaler Also here is the most up to date design. I added a cross member support to wrap around the output shaft for added rigidity. I also lowered and pushed back the tranny about 5mm. Once I start my shapeways shop I’ll upload the plans. Should be a cheaper front motor conversion than most. https://uploads.tapatalk-cdn.com/201...95e2029a07.jpghttps://uploads.tapatalk-cdn.com/201...9268c00f56.jpghttps://uploads.tapatalk-cdn.com/201...01212a3032.jpg Sent from my iPhone using Tapatalk |

Re: 1.9 Wild Worm Scaler Nice mount! Which 3D modeling software are you using? |

I will definitely be building a custom T-case mount when it comes in and most likely all the parts for my blackfoot body. |
Re: 1.9 Wild Worm Scaler Is your project up and running yet? Scale Mountain is calling for a test run, let's go!:) |
Re: 1.9 Wild Worm Scaler Got some more work done! 3D printed an engine to cover the motor. Not sure what kind of V8 it is but It was free and it’s got a ton if detail. I also printed a new cms mount to move the servo a tad bit lower and further back so I can get the winch bumper as close to the body as possible. I converted the axial transmission into a temporary transfer case. I finally started fitting the Blackfoot/f150/ranger body. Most likely gonna open the fenders a bit, do a half cage tire rack and an interior. https://uploads.tapatalk-cdn.com/201...0ea17b862e.jpghttps://uploads.tapatalk-cdn.com/201...341b2dcf57.jpghttps://uploads.tapatalk-cdn.com/201...cac2dac850.jpg Sent from my iPhone using Tapatalk |
Re: 1.9 Wild Worm Scaler Had the day off today so I got to mess around designing more parts. It’s funny how you go to solve one problem only to create more. So it started with boat sides to eliminate the side skids. Once I got those figured out, the fenders I printed didn’t fit. So I had to go back and modify them. After getting the fenders situated I realized I wouldn’t be able to use the OEM receiver box. So noot having a Traxxas one on hand and it being too late to run to the hobby shop. I decided to design the lower part that will take the original cover. I found my spoil of black nylon so as long as the printer cooperates they should come out nice.

Thanks! I’m actually about to fly out to PHX for work and I’ll be taking the crawler with me. Hopefully she’ll test alright.https://uploads.tapatalk-cdn.com/201...152922d748.jpghttps://uploads.tapatalk-cdn.com/201...77084b23ee.jpg And here’s a pick of the latest boat sides. I added the body mounting holes and printed at a lower resolution so they’d have built in “sliding grooves”.

Re: 1.9 Wild Worm Scaler That looks Bad Ass! Good Job so far Ronin! Man, wish I was going to Phoenix with my Crawlers. Bet they have some great natural rock formations for crawling. Post some pics if you can! |
Re: 1.9 Wild Worm Scaler I’m in PHX! There’s a lot of rocks to crawl. Here are some pics just before I broke my steering link...[emoji29] https://uploads.tapatalk-cdn.com/201...bf812ea513.jpghttps://uploads.tapatalk-cdn.com/201...9df389f075.jpghttps://uploads.tapatalk-cdn.com/201...bf812ea513.jpghttps://uploads.tapatalk-cdn.com/201...6f078a232e.jpg Sent from my iPhone using Tapatalk |
Re: 1.9 Wild Worm Scaler Look at those Rocks! Nice. |
Re: 1.9 Wild Worm Scaler Crawling in PHX really did a number on my truck. I decided I’m going to need all new links because I broke or bent most. Since I’ll be making new links I’m going to extend the wheel base out from 11 to 12 inches. Or closer to what most trucks have. I noticed I kept getting pinched between rocks with the short base. Oh and while I was gone my transfer case came in and it looks sweet! I’ll probably drawing up a skid for it here soon https://uploads.tapatalk-cdn.com/201...b8ab3ac4c2.jpg Sent from my iPhone using Tapatalk |
Re: 1.9 Wild Worm Scaler Sounds like you had one hell of a time in Phoenix:lmao: Get that sucker running again so we can go to Scale Mountain! |
Re: 1.9 Wild Worm Scaler Little Big update! Had a comp today so I needed to get it running and ready to go. I was able to design and print the transfer case mount. Will need to work on it a bit as I think the input shift is a little to high. I also fabbed up a makeshift bed so I can put my scale stuff on. During the comp I over heated the motor so much it melted off the brush holding bracket. (I guess that’s what happens when you run a 19 turn with a 28 tooth pinion lol!) But I was able to change the pinion and put the motor back together and finish the last two courses. Long story short after all the mess I came in 3rd overall out of 20 people! https://uploads.tapatalk-cdn.com/201...d740bfd797.jpghttps://uploads.tapatalk-cdn.com/201...93797d8966.jpghttps://uploads.tapatalk-cdn.com/201...a9058b2716.jpghttps://uploads.tapatalk-cdn.com/201...8835b2b356.jpg Did find some stuff I didn’t like. Next changes will likely be shorter shocks, thicker oil, and a pan hard for the front to reduce the side to side play. Sent from my iPhone using Tapatalk |
Re: 1.9 Wild Worm Scaler Congrats on your 3rd place finish, good thing you had a buddy at the comp to help you out with a spare pinion:mrgreen: Truck looks great, you did well at the comp. |
Re: 1.9 Wild Worm Scaler Rig is looking pretty good. Like the flat bed. |
Re: 1.9 Wild Worm Scaler Quote:
Thanks! I threw it together last minute so I could get some scale points. Probably going to go to a drop bed of some sort. Anyone have experience with mounting the top of their rear shocks more inwards?thinking I can maybe lower the height of the shock to get more clearance for a bed. Sent from my iPhone using Tapatalk |

Mehhh I think I’ll keep it as an offering to keep me from competing in class 3! Sent from my iPhone using Tapatalk |
Re: 1.9 Wild Worm Scaler LOOOOOLLLLL, if you tried Class 3, you probably wouldn't finish so stick to your class, and I want my pinion back.....:lmao: |
Re: 1.9 Wild Worm Scaler Quote:
As for lowering the bed, maybe look into a cantilever setup. I ran the Yeah Racing x Dinky RC cantilever on my scx10 for a while but the shocks that they use are 1/16 revo/summit shocks. They are just too small to make it handle well IMHO. I saw a company advertising a rear cantilever suspension system that had more 'normal' sized shocks that should provide better suspension handling. I want to say that is was Boomracing if I recall. But yeah! Check it out and see what you think. |
Re: 1.9 Wild Worm Scaler Quote:
Yeah they hold up pretty well actually. I haven’t used them for anything super heavy duty yet bu all else seems to work well. I saw the cantilever suspension and it might be worth messing with in the future. Sent from my iPhone using Tapatalk |
