Senton Finally a new Arrma build

calebgilmore · Mar 24, 2025

Been doing the UDR thing for quite a while, but doing a few arrmas again

I picked up a mojave exb roller chassis for $230 i'll get to in a bit but started a tlr senton build last week. Ordered the tlr arms/turnbuckles/hex/plastics set/steering rack/hinge pin blocks/drive shafts and more i probably forgot to go with a used tlr chassis i already had off a used noto I bought a while back. Added in some basherqueen senton towers, top plate, and ackerman to the mix with the latest spektrum electronics. I am still having a hard time using spektrum stuff but i want to run this one on 4s on a small slick concrete track so no need to get crazy with it!
I did order the front diffs out of a felony since they were geared higher than the rest to maybe help with a little more speed at the lower voltage. I hadn't ever messed with felony diffs and i swear it was smooth when i took it out of the bag but when i shimmed it and put a tekjo gasket in i couldn't get the mesh to feel right on the ring and pinion, and when i put the cover back on the bulkhead it locked it up.... I yanked the tekjo gasket and went back with a stock but that wasn't my issue. i ended up not putting the cover back on tight which i'm sure will bite me in the butt. I may have to snag some aluminum cases for this build... I'm trying to keep it light so i may just have to throw some typhon or kraton diffs in instead. Jenny's forgot one diff in my package and i got it this weekend so i'll tear it down and shim it and see if i have the same problem. I guess i could try a different bulkhead on the rear if this front one works out fine.
I was going to use the typhon arms/drive shafts but i'm starting to worry about the body rubbing on the wheels so i dug out a set of senton arms and should have the rear dogbones here tomorrow so i can swap those back in as well.
Finally found the senton boost 4x2 bodies on sale and a cheapo ebay slash special i'll fiba tape and e6000 and put all kinds of stickers on for running and tearing up. I'll have to troll on the facebook pages and say "check out my senton boost! what upgrades should i do???"

I also ordered a cheap set of regular aluminum hinge pin blocks i may swap on as well. the rear was a bit of a bear with the angle the pins end up at and me not knowing if i have the right inserts in the tlr block either since i don't have a tlr typhon. Also found out i didn't have any swb tower to tower braces so i bought 4 on jennys to justify spending more on shipping than on the parts i needed hahahaha.

Subbed. Welcome back to the fold, man. Glad to see that you hit the ground running!

No updates this week, i didn't get the hinge pin blocks in time. I also put together another udr for me and set one up for a friend

I did e6000/fiba tape the cheapo body and ordered some lit decals from miguel garcia though for it.

A little update- Got to work on the front diff this week and get the front end all set up. Got the drive shafts in for the senton setup and swapped the senton arms/shafts on the rear. Got the front diff shimmed and fluid swapped and found it bound up too when i went to tighten the cover down on the bulkhead. I did check it before and it was smooth so I have no idea why i am having this issue unless i was tightening it more than i have ever tightened one before

I've built around 35 6s trucks and not had this issue til now! i backed the screws off a half a turn and it is still a little tight but i don't want to wreck the gears. I may be doing metal bulkheads or swap to typhon diffs/bulkheads before it's over.
Speaking of that, i ordered ARAC3989 the front cvd's for a senton on amazon and what i got was ar310587 which does say everywhere it's the replacement for the part number above, and that it's 85mm but....

Guess what don't fit... so i ordered again on amazon and guess what i got instead of arac3989? yeah, same thing, and it came from the arrma store on amazon. so i thought ok, i'll order on horizon

Aaaaaaand i got ol 310587! I got on the HH chat and told the person on there that this cvd does not in fact fit the senton and is not 85mm. Searched all over google and ebay and all of them have the "replacement" part. I did order one on ebay that says it is the 3989 but we'll see. i sent the seller a message asking and of course didn't hear back. I may have to steal the senton cvd's off another senton i have a beetle body on and just put it on typhon arms/drive shafts instead....

Still emailing with HH, but I pulled a senton cvd to take a pic next to the “senton” ones to send them

calebgilmore · Apr 22, 2025

Small update, i got the correct cvd's but i had to get them off a member on a fb page. I'll get the senton finished up this weekend when i'm off and hopefully get to drive it some if the weather cooperates.

....aaaaand i couldn't pass up the el cheapo aluminum bulkheads on aliexpress and some cheapo aluminum center braces from ebay...

Had good luck with one set of cheap bulkheads so i'll give them a go again. The binding on my diffs with the cover fully tightened is still bugging me. We'll see how they do in these or it'll get a set of typhon diffs regardless instead of the felony fronts.
