    Servo choice

    Hi, I plan to convers my e revo to a single servo direction.
    I just want to know if this servo can handle the task : http://www3.towerhobbies.com/cgi-bin...&I=LXMUS4&P=ML

    With the new mamba firmware, we can chose the Voltage for the servo, receptors and so on, is a receptor can handle 6v without a Bec ?

    Thanks a lot guy

    the stock servos have 250 oz together. Your choice 130 oz...

    might consider if its powerfull enough....

    Ok so I have to put an other one like this one http://www3.towerhobbies.com/cgi-bin...2&I=LXTHR3&P=K

    Is that really needed to put metal horn and arm ?

    do not know what fittings are needed. just know you gotta have the power to pull the wheels..

    It can be mounted and I guees it becomes obvious when you have it in front of you what fittings to use,,,

    others at the forum will be able to tell you, just wanted to remind you of the 250 oz that the 2 stock servos deliever and
    one delivering 125 is not enough :-) so the first servo I think is too weak..

    I still like my stock water resistent ones :-)

    this servo is several members choice for "single" servo upgrades.
    As far as needing a metal horn and arm, your factory one should be compatible. So, I would say, No, its not "needed. But I what do I know, I just bash em and break em!

    And I agree with MWI, I like the waterproof stock ones. I've only had 2 go bad. And at $15-$25 to replace AND be waterproof, that seems reasonable.

    with a hitec servo, you'll either need to buy traxxas servo arm kit, which comes with different arms for aftermarket servos, or buy an aluminum arm for a hitec. the last hitec I bought came with an aluminum arm.

    if you want to use your current arm, you're going to have to use a Futaba servo, as the spline count is the same between Traxxas and Futaba servos.

    Personally, on my single servo steering trucks, I use a JR 9100T servo. They work great for me!

    I have only have one stock servo gone bad in 2 years...

    I think they go nicely with the EREVO/ERBE..... like they were made for it :-)

    but The idea of a better servo with metal gears and so appeals to me but as far as I know they are not sealed like
    the stock ones....

    that must make the truck weaker when you want to have fun ...

    Pfft, waterproof servos- you do realise guys that all servos have an O-ring seal between the different parts of the case; to water proof a normal servo all you need to do is stuff it full of grease & apply a small dab of plasti-dip or silicon sealant around where the wire exits the case. Using that method you can have a single digital metal geared servo thats more than twice as powerful as the stock servos and is also waterproof, and costs less too- see:

    http://traxxas.com/forums/showthread...ing-Servos-Now

    No offence intended & Im only trying to help you save money/ effort, but repeatedly buying stock servos or replacement gear sets is a mug's game; until you've used a better quality servo you don't know what you're missing out on...

    You are absolutely right AOD... its just also a bit confusing with all the servo threads..

    do you have a shopping list for all the right parts needed for a decent single servo setup ...meaning the right arms, horns
    etc

    thanks a lot

    The only special part you may need is a horn to suit the spline count of whatever servo you go with- I only use the supplied plastic horns usually, no strength issues usually but YMMV. For metal options:

    http://www3.towerhobbies.com/cgi-bin...?&I=LXHGB3&P=7 traxxas horns for other brands

    Take your pick for colour/ brand & style really. All you need to do is center the servo, install the horn, connect linkage & tweak steering trim as required.

    Thanks I had already chosen the golden horizon, it looks good.
    At my shop, he has a Savox 20 kg, I think it is a pretty good servo, what do you think about this brand ?

    I have a Savox servo too- great little motor and very fast too. If you know the model number that would help, there are various different savox servos & some are geared for speed, others for torque so only certain models would be ideal for a fast/ heavy truck as such.

    That Im not sure of, cant remember the spline count of savox ( hitec is 24 ), but Im sure you can track that info down easily enough.

    Yes, the web site of savox is well done, so it is 25 T, go for futaba horn.
    Thanks AOD

    How do you guys normally link the single servo horn to the servosaver/steering?

    Just to test it out i used one of the plastic horns that followed in the pack, and just conected it to the steering link with a screw straight into the plastic horn for now..

    Want to use the alu horn, with a good steering linkage, so i`m open for ideas..
