Traxxas UDR #ahbeef
 

Just got my UDR from FEDEX today. Applied a couple enhancing touches to make it look a little more authentic. Figured I should take a pic before I run it because it is the best it is ever going to look, lol.

Nothing ground breaking, just some authentic logos.

Very nice! Traxxas crushed it with this truck.

Re: Traxxas UDR #ahbeef
 

There's going to be one of them on my shelf this summer! I can't wait until they get in stock online!

Sweet looking truck btw.

Re: Traxxas UDR #ahbeef
 

Took it out to the farm and ran 2 4S packs through it. I had the stability management (TSM) knob at about 50%. It handled really well. I think the larger size makes it rotate slower so you can catch it easier. I did try turning the TSM down all the way and without any expo dialed into the steering it became a bit of a handful. I think I am going to keep it on 4S because it seemed to have plenty of power but not a ridiculous amount. Dusty pic below. I think it looks even better now. haha.

That's bad ass.

Re: Traxxas UDR #ahbeef
 

And....the servo died....on vacation. Can anybody recommend a good fast servo in the 200 oz. in. range with a speed faster than .17? It comes with a 2075X which I think is the stock servo in the TRX-4.

Re: Traxxas UDR #ahbeef
 

There are likely faster ones out there, but the DS3218 meets the requirements, and is super-cheap, stronger than you mentioned, and has been working great since December for me in my heavy Ascender build:

Brand: DS servo.
Item: DS3218 20KG Large Torque Digital Servo.
Stall Torque (5V): 19 kg/cm (263.8oz/in)
Stall Torque (6.8V): 21.5 kg/cm (298.5 oz/in)
Speed : 0.16 sec/60°(5V) / 0.14 sec/60°(6.8V)
Operating Voltage: 4.8 ~ 6.8 DC Volts.
Dead brand: 3μs.

All metal gears, listed as waterproof...

Available from many sellers for under $20 "thumbsup"

Re: Traxxas UDR #ahbeef
 

I went with a SAVOX SA-1256TG. Seems to be working pretty good in my test runs today.

Dimensions(mm): 40.3x20.2x37.2
Weight(g): 52.4
Speed(@4.8V sec/60): .18
Torque(@4.8V oz-in): 222.2
Speed(@6.0V sec/60): .15
Torque(@6.0V oz-in): 277.7
Gear: Titanium & Aluminum
Bearing: 2BB
Case: Aluminum
Spline: 25 Tooth

It was a direct bolt in, no dremeling of the motor cover like with some others. FYI the BEC in the VXL-6s is a 10A 6.0 volt unit.

I got lights! Proline 6" LED kit. It is a little shorter than I would like but it will work.

Re: Traxxas UDR #ahbeef
 

After much debating and having to cancel an order on a Baja Rey, ive got a UDR coming on tuesday. Cant wait to get it to some of the local bashing spots. Ive already got two 4S 6700 Traxxas packs ready to go. I went with the Savox 1270 which pretty much has the same specs as the one you used.

I am wondering if its worthwhile to get a BEC so i can bump it up to 7.4v and take full advantage of it.

Re: Traxxas UDR #ahbeef
 

New tail lights from some place in Poland, lol.

Re: Traxxas UDR #ahbeef
 

I'm not sure the BEC is worth it. The UDR puts out a true 6V to the servo as it sits now and I haven't had any issues with steering. You steer this thing with the throttle anyway. lol.

Re: Traxxas UDR #ahbeef
 

Link to the taillights? Thanks!

Re: Traxxas UDR #ahbeef
 

Ive ran 4 packs through it so far, tons of fun. Out of the box i replaced the Servo with a Savox 1270 and MFR aluminum upper links / trailing arms.

Like everyone else, my shocks were leaking right out of the box. I tightened up the lower caps, but still leaked quite a bit after my first run. Traxxas is sending me rebuild kits for all eight. No other issues even with a lot of jumps. I'm only running it on 4S which is really fast... cant even imagine it on 6S.

Re: Traxxas UDR #ahbeef
 

I run mine on 4S only also. I have some GoPro video of it that I am editing and it is pretty cool. 4S seems to still let the suspension work in its range. 6S I think would be just too fast.

If it ever stops raining I'm going to take it to the in-laws house and run the make shift back yard track there with the GoPro on.

Re: Traxxas UDR #ahbeef
 

First attempt at loading video on Flickr. Not sure the quality is that great. Anyway, this is my Baja Rey on 2S with GoPro Hero 6 black with stabilization on and processed in Final Cut Pro X to stabilize it. Didn't turn out too bad and that is actual speed, lol.

Bump, been a while. Did some paint detail work on the back end. Also just sent an email to my amazing painter about doing a shelf body for this thing. Stand by for awesomeness.

Here's a sneak peak of it mounted up. Got a few more decals to get in the mail and I will post some more finished pics.
