MST CMX Bronco! So this happened. 8) https://scontent-bos3-1.xx.fbcdn.net...47&oe=5EF34929 Been working on this one all weekend (it's been a while since I've built a kit). Ordered it from Australia When My CC-01 Pajero Rally got held up in China. Then this one looked like it might get delayed too, which led to other trucks I now have and/or need to build... LOL Anyways..... Got it built for the most part, but struggled with the stock rx box, (didn't like how it fit and where the wires were in relation to the front driveshaft, which led to a traxxas box added to the rear of the chassis. Fit and finish of the parts and quality of the plastics seems really good. The manual was pretty good too. https://scontent-bos3-1.xx.fbcdn.net...f1&oe=5EF03D8E I thought I was going to have to ditch the stock motor/esc, but was surprised to see it had a drag brake (I thought I had read somewhere that it didn't?). The motor may get changed to a 35T, but for now it's okay. Once I had it together enough to run I went out to that nearby crawling course to check out how it ran. I still had things to finalise (you can see the body posts hanging way down in need of trimming). The stock tires with no foams seem decent, I'm hoping to get some use out of these. https://scontent-bos3-1.xx.fbcdn.net...f6&oe=5EF24C0C https://scontent-bos3-1.xx.fbcdn.net...78&oe=5EF1A118 https://scontent-bos3-1.xx.fbcdn.net...0f&oe=5EF17972 |
Re: MST CMX Bronco! So then of course came the mods and/or finishing touches (but we're never really finished are we?). I wanted some kind of rock rails or something to support the sides of the body (I believe the term for this style is "boat-sides"?). These where a pain to make with the tools I had to work with, but I'm happy with how it came out. I used a scrap short-course chassis from a team durango DESC210, and knowing the guy I got it from, it was the dimetek chassis which is harder/tougher, which explains why it was such a PITA to cut up. ...and then I realized I was going to have to remove the frame rails to get the mounting holes drilled properly. :shock: Thankfully, taking one rail off at a time was not that big of a deal. "thumbsup" https://scontent-bos3-1.xx.fbcdn.net...05&oe=5EF36FFD That looks much better! https://scontent-bos3-1.xx.fbcdn.net...71&oe=5EF0375F https://scontent-bos3-1.xx.fbcdn.net...ba&oe=5EF37F99 https://scontent-bos3-1.xx.fbcdn.net...e7&oe=5EF0943C I also used some velcro on the sides. https://scontent-bos3-1.xx.fbcdn.net...e4&oe=5EF318B3 Then came some finishing touches (stickers), as I always struggle with how many to add. I had my Wife help out a little, and this is what we came up with. https://scontent-bos3-1.xx.fbcdn.net...03&oe=5EF37D43 https://scontent-bos3-1.xx.fbcdn.net...b4&oe=5EF12D76 |
Re: MST CMX Bronco! ......and here's the pay-off! I finally got it out on the trail! It was a short run, but once I stopped trying to drive it like a larger truck the fun began. The stock tires are decent, and I'm hoping they get better as they break in. https://scontent-bos3-1.xx.fbcdn.net...fc&oe=5EF322C3 https://scontent-bos3-1.xx.fbcdn.net...36&oe=5EF2BA88 https://scontent-bos3-1.xx.fbcdn.net...b0&oe=5EF34C52 https://scontent-bos3-1.xx.fbcdn.net...08&oe=5EF34117 https://scontent-bos3-1.xx.fbcdn.net...91&oe=5EF1D553 https://scontent-bos3-1.xx.fbcdn.net...18&oe=5EF1918A https://scontent-bos3-1.xx.fbcdn.net...bc&oe=5EF30CF9 https://scontent-bos3-1.xx.fbcdn.net...ea&oe=5EF0C842 https://scontent-bos3-1.xx.fbcdn.net...d9&oe=5EF21EA9 Things on my to-do list include moving the esc and rx to the sides and getting the battery lower in front. I'll also be adding some lead on top of the servo to help keep that nose down. I ran it with a shorty-pack and it's still way to tippy. The trucks really light, and feels too bouncy. I've got the softest springs in it, and stock shock oil. Does anyone make a metal version of the oddly shaped servo horn MST uses? |
Re: MST CMX Bronco! Did some more work to the CMX! Lead, and general weight tuning happened. Shorty-battery moved all the way forward. I had thought just behind the axle would be better, but nope, I was wrong. 1.5 oz added to the servo and 1.5oz added to the chassis. https://scontent-bos3-1.xx.fbcdn.net...bd&oe=5EF8BC68 Light kit I had laying around. https://scontent-bos3-1.xx.fbcdn.net...cd&oe=5EF900FE Axial beadlocks with 1.5oz per wheel. Hot bodies rover tires! I have wanted to find a set for a long time. https://scontent-bos3-1.xx.fbcdn.net...ea&oe=5EF9D60E https://scontent-bos3-1.xx.fbcdn.net...e8&oe=5EF8598B I thought the WB was not quite right when I put the body on. Seemed like the front axle needed to go forward a bit. Added some spacers to the front links. Had originally wanted to build it so I'd lengthen the rear, but with the bumper the way it is I thought this would help my approach angle. I had to do a little clearancing for the servo, but it came out okay I think. https://scontent-bos3-1.xx.fbcdn.net...e6&oe=5EF7FED9 https://scontent-bos3-1.xx.fbcdn.net...bb&oe=5EF82BDF |
Re: MST CMX Bronco! Took the Bronco about a mile up Mt Cardigan today! I was super-impressed with how well it did. It tackles inclines I did not think it could with the SWB and is comparable in that regard to my SCX10's. It's small size it's the only thing that really stops it, although sometimes that actually is a help. The weight added to the chassis and wheels has given it the stability it was lacking, and the Rovers gave it the grip and a little extra clearance. I was very surprised that the 26T motor does not get hot. I does not do too bad at low speeds, and the high end punch for getting over stuff is nice. The esc I'm not sure on though. It's drag brake hits pretty hard (and I'm used to that, but it's a bit much even for me), and also I think it's BSC must be pretty weak. It kept doing this thing where if I held the front wheels at full lock for too long (like when I was trying to take pics) that the servo would go to neutral. It didn't do that before I added the lights, so I'm thinking that's what it is. Anyways.... pics! https://scontent-bos3-1.xx.fbcdn.net...f0&oe=5EF932D4 https://scontent-bos3-1.xx.fbcdn.net...75&oe=5EF9655B https://scontent-bos3-1.xx.fbcdn.net...35&oe=5EF88ED6 https://scontent-bos3-1.xx.fbcdn.net...c0&oe=5EF90EC4 https://scontent-bos3-1.xx.fbcdn.net...2f&oe=5EF6B650 https://scontent-bos3-1.xx.fbcdn.net...5f&oe=5EFA0961 https://scontent-bos3-1.xx.fbcdn.net...d6&oe=5EF83C26 https://scontent-bos3-1.xx.fbcdn.net...1e&oe=5EF6BE50 https://scontent-bos3-1.xx.fbcdn.net...97&oe=5EF8260C https://scontent-bos3-1.xx.fbcdn.net...68&oe=5EF7391C https://scontent-bos3-1.xx.fbcdn.net...1e&oe=5EF90338 https://scontent-bos3-1.xx.fbcdn.net...b7&oe=5EF894B7 https://scontent-bos3-1.xx.fbcdn.net...8d&oe=5EF84E77 https://scontent-bos3-1.xx.fbcdn.net...bf&oe=5EF8E789 |

Re: MST CMX Bronco! I found out pretty quick you need a soft drag brake on these, otherwise they cartwheel downhill! :) This is one of the few truck I run weighted wheels on, it makes a ton of difference. I also have a few stick on weights behind the servo. Looks like you are having fun! |
Re: MST CMX Bronco! Oh yes, the fun-level is off the scale! When I put the HW 1080 in there I might swap the motor with an axial 27T I have sittin' in the parts-bin. I might see if I have a slightly smaller pinion too, but I dunno... I do like that top-end speed it has for places where momentum is your friend. |
Re: MST CMX Bronco! Nice! The CMX is a nice platform especially since it's scaled more on the Tamiya side of 1/10. How's Clodtalk? I haven't visited in a while. |

CT has been slow, I think I post over here more than I do there. |
Re: MST CMX Bronco! Took out the stock esc+motor, and replaced them with a HW1080 and a 27t axial motor. Seems to crawl pretty good/slow, but still has a nice burst of speed when I want it. Seems to have fixed the issue I was having with the servo not holding position for extended periods. Took the CMX over the the Weathersfield trail on Mt Ascutney and it did pretty good. I always take my trucks across that fallen tree. It looks easy, but there's a knot part way across it that will mess you up if you're not careful. https://scontent-bos3-1.xx.fbcdn.net...6a&oe=5F0A8E44 https://scontent-bos3-1.xx.fbcdn.net...27&oe=5F0B4361 https://scontent-bos3-1.xx.fbcdn.net...48&oe=5F09BB2C https://scontent-bos3-1.xx.fbcdn.net...b1&oe=5F0B8211 https://scontent-bos3-1.xx.fbcdn.net...73&oe=5F095DE9 https://scontent-bos3-1.xx.fbcdn.net...09&oe=5F0B648E https://scontent-bos3-1.xx.fbcdn.net...f0&oe=5F0A81F8 https://scontent-bos3-1.xx.fbcdn.net...89&oe=5F09320D https://scontent-bos3-1.xx.fbcdn.net...01&oe=5F09EA0F |
Re: MST CMX Bronco! This truck keeps on surprising me. Some of the steeper stuff it pulls off I really didn't expect it to do. <iframe width="560" height="315" src="https://www.youtube.com/embed/zTv86jDP4n8" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> <iframe width="560" height="315" src="https://www.youtube.com/embed/pScy-pgnlWE" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> <iframe width="560" height="315" src="https://www.youtube.com/embed/8cQLPc15pzM" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> |
Re: MST CMX Bronco! Took a run up the Brownsville trail on Mt Ascutney today. Gave the CMX Bronco a workout. Unfortunately on the way back down there was some carnage and I found myself with 3WD. I thought I had sheared a front CVD drive pin.... turns out the whole ball-end of the axle shaft snapped right off, so the Bronco is out of commission until new parts arrive. https://scontent-bos3-1.xx.fbcdn.net...28&oe=5F3CC364 https://scontent-bos3-1.xx.fbcdn.net...7d&oe=5F3D6B37 https://scontent-bos3-1.xx.fbcdn.net...bc&oe=5F3D1856 https://scontent-bos3-1.xx.fbcdn.net...f1&oe=5F3BF4AC https://scontent-bos3-1.xx.fbcdn.net...6a&oe=5F3BC34A https://scontent-bos3-1.xx.fbcdn.net...84&oe=5F3D72C0 https://scontent-bos3-1.xx.fbcdn.net...8d&oe=5F3C2F4E https://scontent-bos3-1.xx.fbcdn.net...ba&oe=5F3E8A57 |
Re: MST CMX Bronco! ^^ Looks like an awesome place to wheel! |
Re: MST CMX Bronco! Quote:
So about that breakage. I'm still kinda' shocked that the whole ball-end of the axle shaft snapped right off. I was looking at parts in stock over at A-main and was happy these were in stock, but noticed something.... the same part (with the same joint design) for the CFX-W was out of stock.... and oh my!... there were some very bad reviews of that part.... I mean ALL seven reviews were bad, not a single good one. That's too bad, as I was really interested in the CFX-W, but not any more. I'm guessing it's not as big a deal with e smaller-tired rigs like my CMX, but "lucky-me" who runs 3S and bigger/wider than stock tires with some weight .... :???: https://www.amainhobbies.com/mst-mpa...310094/p618344 |
