My "New" JRxPro SE Build thread

[TRX-1-3]

Alot of folks get their reproduction decals from MCI
https://mciracing.ca/collections/team-losi/products/1-10th-losi-jrx-pro-se-box-art-decals?sort_by=manual. They have jrxPro and SE decals. Unless your original decals are all creased up or have shock oil spills/stains on the backing paper, they should be fine as far as adhesion. But if you don't want to cut your original sheet just to find out, MCI is a good place to look.

Thanks much. I’ll order. I wonder what that premium color option is all about for 50 pct more? I really just want the hard body shock decals since mine were ruined from years of shock oil.

It makes the brushed and mirror colors active.

Did a few more things yesterday while I wait for parts.

Completed assembly of the hydra drive by piecing parts together from eBay finds. Forgot about the silver spring. Had to purchase that separately along with a rebuild kit. Filling it up was no easy task. I eventually found that adding oil prior to sandwiching the halves together was easiest way to clear air bubbles. I then worked the internal rotor several times between topping off. Hopefully I did it right. Had to fashion a tip for the silicone diff oil I used, which was 7k.

Added a stainless screw kit and also custom cut a chassis protector to keep the chassis mint.

Another subtle change was the battery clip rubber holder to prevent losing it along the way somehow. I like paying attention to detail.

Hopefully I’ll install the jammin’ steering enhancement kit soon. RPM ESC tray is on the way.


For now I’m sticking with a modern Tekin ESC and 13.5T brushless motor. Eventually I’ll probably revert to older Novak electronics and a cool retro motor if I can find one.

Photos of finished electronics. Tekin RSX Pro and g4 motor combo. LRM high speed fan. Ruddog 3600mAh NiMH battery. The only battery I could find that fit properly. Added NOS RPM ESC shelf. Will be installing Jammin’ steering enhancement kit soon.

Hopefully I will also find ball bearing bellcranks and the steering servo brace kit in the future.

I know this setup is kind of a resto mod with modern bits on a vintage new chassis but I kind of like the look. At least until I find the right vintage electronics.

I chose Tekin because of its long history in competition with Novak. But truthfully I find other ESCa and motors of better quality. The Acuvance electronics I’m using
In my Yokomo MO 2.0 are much much better overall.

I stripped and recoated the links and ball studs for my pro and pro se last night using a Caswell black oxide system. It works great as long as parts are thoroughly clean and dry.

Does anyone know a place where I could get titanium upgrades in 4-40 if I want to make the switch?

I already purchased a set of 12 RPM ball cup rod ends to replace the short originals on the pro. They really suck vs. the upgraded gray ones Losi implemented on the pro se.
