Here are some pics of a project ive been picking away at for a while. Got a TXT1 a few years ago and turned it to a crawler now going back to how it was intended and should be. When i was crawling and looking for a lower cg i experimented with the Axial transmission. Obviously you always could run just one motor in a TXT but check out how much lower it can go. Always was confused why Tamiya put two motors up that high but what do i know. Progress is at a standstill for a while. Too many projects not enough funding. Have to take a photo lesson cause a lot of the closeups are blurry.
Stock one for reference
Moved around some chassis supports

You can see the STRC AX10 transmission mount is drilled perfectly for the Tamiya chassis holes and i think it was less than 15 bucks off ebay. I just used the bumper spacers as a temp mockup. For sure use some alum ones later or maybe come up with something light enough and still take up that space.
Made these servo mounts out of i think a 1inch alum L bracket piece. Not the prettiest but i think they may do the trick.
Wanted to get rid of the cantilevers and everything up high. I robbed the lower links and shocks of my Clod for the mockup. I just used the stock top links but put them in a diff location. That Tamiya lightweight chassis has those extra holes it works decent for that plus gets closer to squaring up all 4 links. The axles still may need to be turned somemore.
No top plate yet to hold batteries but those are wicked strong single cell lipo's(3.7v). They dont match in the pic but the one is a 6500mah 100c. I have seen some guys run them in their sc trucks. Im sure two of those wired rite will power about anything plus if there is any onroad racing near bye you can buy them used pretty cheaply. 12 scale carpet racers use them and those guys seem to cycle out of their stuff pretty regularly. Also there is room under the batts and above the trans for a sc i think. Maybe mounted sideways directly to chassis? Have to come up with a receiver mount but that shouldnt be hard. There is only two body mounts just to give a reference. Those are Traxxas Slash front body mounts and the width is pretty close for a 10th scale truck body. Maybe need to be shortened a little and there is 4 holes rite there. Pretty close together so not sure how ideal that may be. Guess the body mount bracket that is on top of my Ripper Clod could be mounted up there but im sure the stock mounts would be lighter and work just fine. The shock mounts are something i made when i was crawling. They are copied off stock body mount brackets with 3 holes added and i used them to mount some long Savage shocks on my crawler and still used the stock body mounting plastic parts. They are flipped upside down and mounted on the inside and i put some tape on them so they wouldnt scratch up my pretty blue chassis. Probly need either a brace between them or secure to the frame in a third spot.
The final hurdle to clear is the driveshafts. Biggest problem is the Axial trans has 5mm outdrive and the TXT has 6mm. Im thinking of useing a Robinson hardened output gear with the trans. and use Tamiya F350 yokes and get some steel rod and redrill it for the pins on the one end and make my own axles. I hate the idea of steel driveshafts though and wonder if i could combine Wheely King yokes with Revo yokes and make something that would be cheap. Not sure if the Wheely King yokes are 5mm? Ideally make something that not only works but be a fuse in the driveline system and you could just walk into any RC store for parts if/when they blow up.
