    Yeah man, it's nice to see a different take on the UDR coming together.

    I got my front end buttoned up, and I'll eventually post some pictures to my build thread.

    It'd be nice to get our UDRs...

    Thanks for those findings on the GPM housing. I'll probably switch the planetary housing back to plastic, but use the rest of the aluminum housing. My input pinion has a bit of wiggle that I don't...

    It'll be a bit before I get one, as my RC money is going to go to my ESC first. Post up what you figure out with it, as I'll probably be copying you.

    An interesting solution for the front could be the RPM skid plate. It's a 3 piece design and appears to allow you to delete the bumper and possibly the bumper / skid plate connection.

    Could be...

    From one of the guys on the forum who has the black satin cage, the finish isn't very durable. I've been painting my new cage pieces with Testor's silver, and it looks pretty good. It isn't likely to...
  6. I have a new set of cage sides coming too,...

    I have a new set of cage sides coming too, because I want to be able to swap between Trophy Truck and U4 depending on the terrain. The cage is actually pretty cheap if you avoid the black satin...

    Nice! You made your cuts a bit closer to the cab than I did, as I cut right before the fuel cell.

    I drilled holes into the cage members that were left, and attached the stock bumper right to where...

    I have upgraded the servo to a Savox SC-1256TG which is around 300oz of torque. I don't remember exactly what the specs are.

    I should have replaced my servo saver when I had my UDR entirely apart...

    I have heard of people wearing out servo savers on the UDR and needing to replace it.

    I wonder if that's the case for me, as my UDR has been turning pretty poorly at low speed. I've noticed it...

    Making the front shorter is indeed a challenge. I cut off the fuel cell, shortening the rear cage significantly. I then tried to figure out a way to shorten the front, but came up with nothing.

    The biggest "hang-up" to the UDR's rock performance was the planetary housing on the rear axle. It's huge, and mine's made from aluminum which is not a rock-friendly material. That's the only...

    Well, I'm on board this U4 train. The UDR is a blast as an Ultra 4 truck.

    My son and I were driving normally at a spot near our house, he driving his Axial Yeti and me on the UDR. When all of a...

    I stand corrected. According to the 2021 U4 rulebook, there is no restriction on tire size for the 4400 class. The racers might be commonly running 40" tires, but that's up to them.
  14. Hey man, I don't know how scale or class specific...

    Hey man, I don't know how scale or class specific you're trying to keep your build, but if you're shooting for a true 4400, you might not need to worry about larger tires.

    I think the 4400 class...
  15. In the interest of lower-speed rock crawling...

    In the interest of lower-speed rock crawling (Ultra 4), the 70/30 Throttle Neutral setting provides pretty good low speed control with no cogging.

    It still probably isn't as nice as a sensored...

    Oddly enough, I feel the opposite way that you do. I like the UDR because it's my "drive it like a real truck" truck. It scratches the itch that other models don't. I like paying too much attention...

    That's a bummer to hear. I've got 5-10 batteries on my GPM axle housing, all of which were in very fine sand and dusty dry dirt.

    My housing was clean on the inside after the aforementioned...

    Since I'm sending this back to the finisher for pictures I wanted to get it looking nice.

    I decided to re - paint the cage panels so they look fresh. I also painted the lettering on the tires,...

    Sounds like a good plan to me. I'm glad to see someone acting on the U4 potential in the chassis. I'm surprised there hasn't been more of it already.
  20. Yeah, I can buy that. The "slapped on" was an...

    Yeah, I can buy that. The "slapped on" was an overstatement likely motivated by some pro-Traxxas bias on my part.

    And yes, if you want a scale model you can really abuse, I think Losi would be...
  21. My main beef with the Losi offerings is that...

    My main beef with the Losi offerings is that they're still just a rolling chassis, with a rollcage slapped on top instead of a lexan body.

    The UDR is actually a complete scale chassis, so its...

    I got the cage back from the Cerakote applier, and I'm conflicted. I really like the way it looks, but now I'm tempted to shelf queen it. Hopefully the durability of the coating proves to be durable...

    Oh yeah, I'd be down. I've floated the idea of building an Ultra 4 truck off of the UDR, but never got any interest. It's got the chassis, the suspension and the drivetrain for it.

    Traxxas did a...

    I suspect driving style and terrain are factors in driveshaft wear.

    For example, my truck doesn't see much air time, but it does go through all of its rear travel several times in one lap while...

    I use the stock driveshaft, but I only run 4S and I drive pretty carefully.

    Even on 4S, I can only get 30 battery packs or so out of a driveshaft before the buzzsaw noise drives me to swap it out.
