My TXT for your review Here is mine. I have been working on it for years little by little. It has seen dirt twice lol. Stock motors, 9 tooth pinions, Home made servo mounts, lenthened to 15 inches, JB welded diffs, screwed tires to rims, wiring wiring wiring. I run it with a HiTec Laser 6 twin stick and that has been a PITA to get to work right. I drove it today and guess what? I'm not done!! Good thing I like to work on this lol. I have an RS10 to drive. I think I stripped my rear servo and the truck leans WAY over under throttle. I bought some aluminum to make suspension and steering links. I'm ditching the cantelevers next. I ran the stock shocks where the canti arms go and the arms where the shocks go. It helped the twist but lost the articulation so I switched it back...I need the middle ground. Here's some pictures. Also top heavy, needs wheel weight all that stuff. But it looks good"thumbsup" http://i246.photobucket.com/albums/g...100_2244-1.jpg http://i246.photobucket.com/albums/g...e/100_0191.jpg http://i246.photobucket.com/albums/g...100_2243-1.jpg http://i246.photobucket.com/albums/g...e/100_2323.jpg http://i246.photobucket.com/albums/g...e/100_2319.jpg http://i246.photobucket.com/albums/g...e/100_2321.jpg Thanks for looking! |
your title says review. Were you looking for thoughts and ideas? seems a different setup in each pic. (cantilever on one, shocks outside, shocks inside?) My first thought would be to lower your body as much as you can without it rubbing tires. If you are looking to improve the best way is to copy someone that already put the time in experimenting. Then tweak from there to personal preference. Tuning is addictive though. I have done sooo much research on suspension geometry it hurts my head. Squat, anti squat etc... worth your while though.. Torque twist can be fixed with just proper geometry. |
Good eye, Yes each has a different set up because I work on it alot. Copying someone elses truck I feel is a short cut and I will miss all of the knowledge gain in the process, I'm interested in learning the right way and why. The last three pictures are the current setup. I'm planning to cure torgue twist with springs and shock oil. Maybe new shocks and a different mounting place. I'm thinking of switching to 1/4 servos after doing some reading here. SO I may scrap the old mounts and start over there. I think what I like best about this truck is that all of the mods have to be thought up, fabricated and tried. Its a thinking mans game, I enjoy the experimentation both good results and bad. Any idea's are welcome and will be added to my long list of things to try. I will have this truck for a long time just because the possibliltes are endless. I have the body where I want it, If you notice some tasteful trimming had to be done. If anything I will have a different body to crawl with but just for looks this is how I want it. Thank for looking"thumbsup" |
First you want to keep your lower links and lower shock mounts as close to the tire as possible. the farther out the more stable the chassis. And its not all about flex with a shaft rig. Sprung weight of a hanging tire to a certain degree keeps a rig from flipping over. For springs you want almost stiffest you can that will allow full travel of your shock. A good way to start with torque twist is by doing the rear first. When up hilling all the weight is on the rear. Lockout your front suspension. Put some sort of link so it wont move and is at ride height. Make a high traction steep incline (carpet works good). Start with your links parallel then close the gap up front by lowering your upper link mounts. Unfortunatly you will have to drill holes in that mint chassis. Which is why its good to have someone else go first. I could go on for days, but this is my favorite part of crawlin. Unfortunatly I do not have a txt so i cant completely help you on that. Someday i will. "thumbsup" |
Thats what I'm looking for! Something to test, find the sweet spot thru testing. I want my soon to be wife to shake her head at me when I spend an entire Saturday driving up a carpet ramp over and over and over"thumbsup" Since I was planning a new servo mount to house some 1/4 scale servos I can remove the grey plastic mounts for the lower links and shocks. I can build the new mounts into the servo mount and can move the suspension where ever I please. I like your methods and they give me a great place to start, which I needed. I have seen guys on this site that mount the upper and lower links into the same hole on the chassis. I might start there. I bought 80 weight shock oil today but they didn't have the springs I was looking for. I think TXT-1 is code for Test X Tune - 1 more time :mrgreen: I will take lot of pictures of the Fabrication, tests and finished modification, I love pictures and I know everyone else does also. Do you think the top picture is about what I should shoot for with articulation? Just a little more than a TXT tire. |
you mentioned mounting top and bottom links in the same location... i really think you should keep the triangulation so you have more stability. ive never tried it with a txt, but my clod had nearly parallel links and it caused the axles to sway. i definitely prefer the og triangulated setup. however, id love to hear a review if you try it! "thumbsup" |
hey man cool rig! as for your thoughts on shocks vs cantilevers , ditch the cantis and put 4-6 inch shocks in that spot, and it is awesome |

i have never run cantilevers so i cant speak on that |
I agree about the canti's. I wanted to try it both ways that's why in one picture I have the shocks up top and another I have then on the axle. I have good articulation without the canti's. But I switched it back to make sure and now I have horrendous body roll. I bet if I try hard enough I can roll the truck with the throttle lol. I'm going back to the other way and will look into some of those 4-6 inch shocks also. Right now I'm going to switch out the radio from a 6 channel twin stick to a three of four channel pistol. I found after running my RS-10 that I have much more control. I also put the steering servo's from this onto my RS-10 and they're much more at home turning 2.2 tires, I'll get 1/4 scale servo's for this beast. I found some small screw-type clamps at work that I can use to test link placement without drilling a hundred holes in my frame. http://i246.photobucket.com/albums/g...e/100_2446.jpg http://i246.photobucket.com/albums/g...e/100_2447.jpg Its stripped down now so I can start over. I have a better idea where I'm going this time. I want to get my electronics installed and fuctioning properly so I can get to tweeking the suspention. I'm switching to lipo for smaller batteries with more run time. My helicopter runs 11.1V 900's and there tiny. So I figure 3s 2000's would work here. Now I am waiting for servos and a radio, maybe a new ESC since I'm running the Super Rooster and I would like drag brakes but we'll see. I will update as I have updates"thumbsup" |
Quick question. I'm thinking of bending my lower links. I know that I can bend them up for ground clearance but what about also bending then in for tire clearance? I might just try it for you guys "thumbsup" |

Its not fast, I don't want it to look like those "low rider" rock crawlers, I have one of those. I like the holy sh*t! factor of this truck, I took it into the LHS and set it next to a guys AX10 and his attention was on mine as was everyone elses. The first thing I hear is lower, naw its as tall as I want it, I'm not going to comp with it I just think it would be cool after a comp to have a little fun. I'm doing crawler things to it but I want it to be easily recognized as a TXT-1 Monster truck, (that can crawl) |
Looks good so far. I am about to part mine out to fund my 2.2 comp. If you have any interest in HR aluminum knuckles x4 front and rear, rc4wd r2HD tranny, gd600, egressor's 4:1 axle kit, or a set of 40 series rockster's with x-locs (99% tread left) drop me a PM. |
You want to keep it looking fairly stock? Take a look at the pics on Tamiya's site; the body is lower. Where you have it just doesn't look good. Here's a thought on copying other people - research on this site to find what works is likely less time consuming that testing various iterations on the truck. I don't want to burst your creativity bubble but for some things going with what others have proven to work is cheaper in time and money. |

So you don't want it looking like this one??? As that is a TXT super. I had a lot of fun with my TXT when it was set-up like yours. As mentioned go waay back, like end of the TXT forum way back, and work your way to newer posts. Lots of good tech on how to set it up and still keep it looking stockish like you want "thumbsup" Quote:
You got PM!! Quote:
Exactly, the body is a couple of notches lower. X2 on going waay back to find good tech for ya! |
The body is where it is now because at one time I had way more articulation than I needed and this is as low as I good go with out having to cut anymore off the body. I think it adds to the overall hugeness of the truck. And if I was building it to the Picture on the box I would have been done five years ago. The last guys TXT-1 is awsome looking and I may end up there someday but like I said I have one like that already. Suggestions on how to improve preformance and what definately doesn't work are more than welcome. But like I said before I will only lower the truck as a last resort. I'll spool $100 bucks worth of solder wire into the wheels if I have too. |
So I got tired of trying to squeeze all of the electronics into the confines of the stock battery holder. I was at Tacoma Screw buying some hardware and noticed the metal area, so I went to investigate and I found the perfect electronics mount! Well I found this.. http://i246.photobucket.com/albums/g...e/100_2462.jpg But I made quick work of it http://i246.photobucket.com/albums/g...e/100_2466.jpg Here it is installed http://i246.photobucket.com/albums/g...e/100_2472.jpg http://i246.photobucket.com/albums/g...e/100_2473.jpg Notice I drilled and tapped the mounting holes instead of drilling all the way thru and using a nut and bolt, just looking for a couple style points. After I finish all of my mock up I'm planning to hit everything aluminum with a polisher. I read on here that turning the motors to the rear and mounting the battery up front is the best way to do it, but I weight them and the motors weigh almost double what the battery pack does. So I spun the motors back to the front and am mounting all of the electronics to the rearish. I may make another panel for the far front of the truck and mount a pair of saddle type batteries up there, I still have plenty of aluminum. I took your advice and read what others have done and I have designed some servo/shock/link mounts. I will take pictures as I build once I get started. Thanks for talking with me about my truck."thumbsup" |
Nice work on the plate. I used an electronics box to keep the ESC / receiver dry. Here's a couple reference pics with the body in the stock location; I'll leave it alone after this. :) With 6 7/8" tires an 3/4" wider wheels, stock shocks: http://i222.photobucket.com/albums/d.../RC/Bigger.jpg With 6.25" (near stock) tires and no wideners, shocks moved: http://i222.photobucket.com/albums/d.../Jeep-Body.jpg |

As for a good location to mount your battery. I have my body mounted lower, if not lower than Mazlem's TXT-1. I will be running dual 7 cell battery packs that will be mounted along the outer frame rails, just under the sides of the door body panels. This way the weight will be lower than if it was mounted on top or within the chassis. I tried to find the link showing a similar truck and I seem to have lost it? |
The motors are in the front in stock form; you can kinda see it in Tamiya's pics. I've put Kyosho TwinForce battery trays on a couple TXT's like you're describing; might be one of my trucks you saw. GreMonte are you gonna run lipo's or regular stick packs? |

This is what my truck looks like at the moment:http://www.rccrawler.com/forum/tamiya-txt-1-juggernaut/231443-txt-1-axle-modification-link-mounts.html Here are the pics I spotted of someones truck that has side mounted battery trays. I plan to mount my battery with velcro straps or some kind of cradle that sits higher under the side door panels of the body. http://i103.photobucket.com/albums/m...k/P4080039.jpg http://i103.photobucket.com/albums/m...k/P4080040.jpg http://i103.photobucket.com/albums/m...k/P4080042.jpg |
Bending links Quote:
Newb here: How do you bend the links? Is it with simple hand tools...or is there a "special" way to do it. Thanks!8) |

I have been working on my truck and will update with pictures soon. I have two hitec 1/4 scale servos and I am building the mounts for them. I'm also changing the radio system. I'm loosing the twin stick and going for a three channel pistol and a PunkRC 4 wheel steering controler. I have taken a little time off from my TXT as I am currently building a TOP SECRET project and once its finished I will post it on RCC. Also I would like to run LiPo on this. I was trying to see how small and how powerful of a battery I could find and I am impressed with whats available. The only thing really keeping me looking at NiMh is of course price and being able to build my own pack to fit any place I wish on the truck. We shall see. |

Anyone want some updates? Well I added a new paint job and new servos, big ones. If you look close you will see an extra set of links, these are my mock up shocks. I am thinking I will go a little bit shorter but I will also use these to lock out the front suspension while I dial in the rear, looks kind of cool though. After building the servo mounts I couldn't help but run them through the polisher. So I have decided that this is a monster truck but I will ask it to climb stuff. I'm not expecting it to climb like my RS-10. SO tell me what you think. I'm thinking of building a seperate battery pack just for steering power to the HiTec 805 1/4 scale servos. I'm also going to mod a TQ3 for four wheel steering since I can't get any answer from the radio manufactures and I refuse to spend $200 on something i can get for $50. http://i246.photobucket.com/albums/g..._2708small.jpg http://i246.photobucket.com/albums/g..._2707small.jpg http://i246.photobucket.com/albums/g..._2705small.jpg http://i246.photobucket.com/albums/g..._2704small.jpg http://i246.photobucket.com/albums/g..._2703small.jpg |
nice paint job"thumbsup" hows the servos, do thay work well? |
I have no idea, I have yet to power them up. |
bump:lmao: |
^ what?!? bump with no update? http://www.rcmt.biz/bd/images/smilies/ban.gif txt looks good, though. |
There's not a lot of action in the TXT-1 section is this a dying truck? Thats sad mine still looks brand new haha:mrgreen: |
Quote:
|
mine arent dying, just getting rebuilds. probably still my favorite trucks to run. "thumbsup" |
Quote:
I have my super class TXT, that I rebuilt, but I don't really take pics while I'm building. Takes too much time away from fab work. But have mine out competing, driving a bit, and just waiting on a couple of parts to get here so its bulletproof. |
Good to hear that there are still people working on these beasts. I have both of my new 1/4 scale servos mounted now. I'm looking for shocks, then I will be setting up all of the electronics for mine. I have only really driven mine a hand full of times so its still new even though its like five years old. "thumbsup" |
Nice updates! Keep 'm running! "thumbsup" Quote:
I simply use a servo splitter for 4ws. (not independent ofcourse ;-)) |
No I tried for independent but it was a head ache. I just want the ability to go from front steer to four steer and crab walk. Modding a TQ3 looks to be the cheapest way. With a servo splitter its always four wheel steering yes? |
Quote:
Not sure what you mean by "always four wheel steering". If you mean the rears will be turning opposite of the fronts, then yes you are right. With a servo splitter it will always be like that. Not sure how you did independent or why you think its a headache, but modding it a TQ3 will do just that... give you independent rear steer. You can control the rear, albeit just center or full lock left or right, independent of the front. I ran a modified TQ3 for a while, then a DX3R with my TXT and it works, but I wouldn't go back after swapping to a DX6i and having fully independent rear steer. Way to helpful to not use it that way. That and I'm way to cheap for a 4PK as I need 4 channels on my TXT. |
Quote:
I will post pictures when I have another update. |
if you have an aero radio you could run 2 aileron setup and just reverse the servos independently with the programming to get the desired effect, ive never tried it but it might work |
