    vxl revo 1/16th thermal shutdown?

    I have had my revo for a few weeks and yesterday I picked up a 2200 mah 2 cell lipo, I was playing with it in my living room last night and the thing went nuts for a few seconds, full throttle and I had no control. It finally tried to climb the walls and flipped over, i picked it up and it started acting normal again for a few seconds. I was still holding it and gave it some throttle and then it went full throttle and then full brake and stopped. The ESC was hot and so was the motor but It didnt feel extremely hot. The ESC is fast flashing a dim red light.

    I could understand it shutting down if i was running it hard and wide open but my living room is tiny and has a huge Christmas tree in the middle of it. My son was running his 1/16th grave digger and I was running the revo, both of us were taking turns jumping a makeshift ramp so it was not being ran hard at all...

    I read the manual and it says this may be stage 1 or stage 2 Thermal shutdown. I let it cool overnight and plugged the lipo back in and it is still flashing a dim red light and will not respond. I then tried the fully changer Nimh and had the same response.

    What should I try?

    Unplug the servo and see if it responds. If so, bad servo.

    White probably has the issue nailed...
    You did have the ESC in LiPo mode, right?
    Whatever it is I just typed... could be wrong.

    Yep, that fixed it! Thank you very much White and Jimmie!!! I was about to mis out on a fun day.. My sons 1/16th grave digger has been making a clicking noise while turning left so I bought an extra 2080 servo yesterday. I guess I will take the gears out of mine that is no good and put in his that has a stripped gear.

    what other parts are a must have for these trucks?
    I already have an extra receiver, transmitter, and i will pick up a few more extra servos. What else should I pick up?

    Instead of getting more stock servos, I suggest upgrading to a better servo. The HiTec 5085 and BlueBird 390 are good replacements... stronger and more reliable. The HiTec requires a different servo horn, but the 390 drops in with all stock hardware.

    This is what I had when I very rarely walked away broke.
    Steel hollow balls (7028x) to reduce slop
    3M mushroom tape along battery doors to hold the body on
    Aluminum knuckles to reduce slop and add strength (I have HR but recommend GPM or GH)
    A BlueBird 390 servo due to the stock being known to fry/strip itself
    RPM a arms at all four corners (Front-80692, Rear-80602)
    Center differential (7014) upgrade to help handle the power of
    2200mah 2S 20C LiPo's ran in parallel for ~1 hour run times
    23/50 gearing gets me to ~30mph yet keeps temps in check
    Shimmed front and rear bulkheads... *LINK*

    Especially do that last part... extremely cheap preventative procedure.

    Is there any programming that has to be done if i buy the BlueBird 390? Im always game for better parts. Do you have a link where i can buy a few? everywhere I have searched they are on back order.

    Thanks for all of the great info!

    There is no programming necessary. The Bluebird is a popular item in the 1/16 Traxxas world, which makes it hard to get.

    You might need to reverse servo direction.
    If you end up finding a BB 390, here is how to set it up:

    BB 390 Set Up

    All stock hardware is used.
    NONE of the hardware included is needed!


    There are tab braces that do not allow the servo guard to sit flush.
    IT IS OPTIONAL TO REMOVE THEM.
    I have done this both ways without any adverse reactions.
    Here is a picture of the braces:

    (thanks goes to danielhr77 for the picture)
    The tab braces create a small gap between the chassis and the servo guard.

    Here is how it plugs in:



    You will also need to reverse the servo direction.
    These are the steps for LINK and TQi radios:

    Hold MENU for 3 seconds
    Green Blinks

    Press MENU
    2 Green Blinks

    Press SET
    Green Blinks

    Press SET
    Red Blinks

    Press SET
    8 Green Blinks

    Hold MENU
    Setup Complete
