    servo horn?

    http://www.ebay.com/itm/Blue-Aluminu...-/370777968805


    Fiance slammed into me today, and broke my servo horn. Again. Ive been through a handfull of different savers and horns. Anyone use a racers edge horn?

    Just so everyone knows, I am running BB aluminum bell cranks, plastic drag link, a hitec 645mg servo, and now a busted horn. LoL. Any pointers would be appreciated.

    Are you using a saver with the setup your running?
    No slipper/tall gearing/power = broken parts.

    No saver. I have a pile of broken savers, broken plastic horns, and a few stripped gears from this servo. LoL

    This truck has big joes on it... guess I forgot to mention that. LoL.

    That's why you're breaking them!!!! The servo saver is a spring that is meant to be the point that moves when theres an impact instead of something breaking. Get a saver on there, and forget about breaking all of that crap!

    I have a pile of broken savers. Between broken ears, stripped splines, or just plain ol explosions. LoL. I have tried traxxas and kimbrough(sp) savers. Neither one has put up with my abuse.

    What style bellcrank do you have? If you have the 4910 version, where the saver goes right onto the output gear, then try upgrading to the 4907 type, it has a built in saver to one of the bellcranks. Not really sure why you're having such a trouble with breakage, but it's obviously not the parts, because everyone would be on here complaining about it.

    Give the 3.3 spec integrated servo saver/bell crank a try. Works well for me all situations except extreme crashes.

    Or just put another kinborough saver on what you got. I have run Jumbo Kong’s with a kinborough and had some major cartwheels/crashes and never broken a kinborough.

    If you remove the weak link (saver), the servo will eventually pay the price.

    Waiting on my axle carriers to come in. She plowed straight into my front wheel and blew the pillow ball out the back of the carrier splitting the pocket open, and broke the servo horn. Beware of new drivers. LoL

    I like the looks of the Ofna servo horns, and they cover most servo spline counts.

    This brings up a question I have. The two screws that hold each tie rod to the bellcrank, do they screw in from the top or from the bottom? The inner screws screw in from the bottom, easy to get too, but mine, the two tie rod ends are screwed in from the top, makes them a bear to get too. Secondly, if they are right, I noticed after putting the new servo on, they touch the dif ring, that little ring with the two pegs. I guess I need to reset endpoints?

    mine toe links on the inside screw to the bellcrank from the top... and on the knuckle side screw to the links from the bottom.. no idea if this is 100% correct but it works fine for me...

    Thanks, I looked through the exploded views and it really didn't show that.

    Ended up ordering a racers edge servo saver. It is contrsucted of both plastic and aluminum, and was cheap. Hope it holds up. If not, I am going with an aluminum horn and will rebuild my servo as needed. Ive already rebuilt the servo once. LoL
