    Servo for UDR

    Hello all,
    I just got a udr and read a little bit about the stock servo is really not that great.
    What's a great replacement servo, waterproof preferred.
    Thanks.

    I fitted a Savox 1256 in mine after reading the great reviews and feedback on here, it’s not waterproof, but like most servo’s as long as you dont submerge it, it will be just fine ��

    Does it come with the arm?

    Twice the price as well lol, the 1256 works just fine for the money


    And the 2292 is 22kg at 6v, so it only has 2kg more Torque??? Unless you run a BEC???

    The 2292 is a very nice servo, but I think there are better options to be had for less money

    My stock servo was always sticking left or right just a little bit unless the truck was right close to me. The savox 1230 has 500oz of torque at 6v and 417oz at 4.8v, same price as the 1256 and double the torque.

    Is that servo a straight fit?

    What should I go with? The Savox 1256TG or 1230?

    Since neither one is "technically" waterproof the 1230 has steel gears and the 1256 has titanium gears with half the torque of the 1230 if I'm not mistaken.
    If it was me between the 2, I'd go 1230, JMO.

    I'm also seeing people running Power HD WP-23KG
    They are cheaper, but not sure how long they last either. I just might get the 1230. I know it's not waterproof , neither is most of the stuff on the UDR. If I submerge the UDR in water I will have more problems than just a servo.
    Thanks for the info, it helped out.

    Suppose I'm a bit late, but I'd definitely go with a Reefs RC servo. Tons of power, waterproof, titanium gears and a full metal housing. You'll never look back.

    100%. Just putting my 2 cents in. Haha. I ran a 1230SG in my Wraith for a while, I just didn't like how loud it was and that it wasn't waterproof. Loving these Reefs though.

    I wasn't aware we could run 7.4HV servos. Do you change a setting for this or is it automatically ran.

    It is a bit annoying hearing it, only to the right. Using the traxxas app only way to silence it is to take the right endpoint to like 70something, then the truck is affected to the right by the reduction in endpoint. I had to shave the transmission cover where that screw is right by the servo corner to get it to lay flat. I will post a few pics tomorrow.

    *water isolation laqui.

    What is *water isolation laqui, could not find it in Google search?

    Reason I'm asking, while putting the battery cover on or changing batteries, the servo will lock out in one direction or another, once I turn the wheel left or right it stops. Even though I changed servos, it still does this, anyone else. A bec may stop it, not sure

    Im running a ProTek RC 170SB https://www.amainhobbies.com/protek-...170sbl/p507825

    Operating Speed @ 6.0V 0.09/60į sec
    Operating Speed @ 7.4V 0.08/60į sec
    Dynamic Torque @ 6.0V 458 oz-in (32.9 kg-cm)
    Dynamic Torque @ 7.4V 535 oz-in (38.5 kg-cm)

    I never took pictures, but someone else took a picture of the fitment, its direct fitment.

    Is a bec required? If so what did you use?

    Does it require a BEC? I was looking at these earlier. Iím hoping to find a servo that just hooks right up with not need much extras. Thereís not much information out there for the UDR yet.

    Thank you. Itís hard figuring out what servo to use. Mine is finally starting to show signs of weakness so I need to upgrade ASAP

    What about the 370tbl? Would that be a good waterproof option?

    check out the dimensions and compare with the 170SB (which is faster than a 370)
