    Question Is An Aluminum Steering Horn Better Than A Plastic One?

    Hi Guys,

    I was wondering if a aluminum steering horn was better than a plastic servo horn?
    If so, what benefit does it give?

    Oh yeah it is. If you get a strong enough servo and get in a crash, sometimes the plastic horn will strip around the splines which key into the servo output gear (even with a servo saver in the steering system). An aluminum one won’t do that, nor will an aluminum horn break like a plastic one could. I swap all my trucks’ servo horns to aluminum ones.

    ^ yep, but I wouldn't buy a metal servo horn if you haven't already stripped your plastic one. Unless you want a failsafe.
    The present is theirs; the future, is mine.

    In buying an RTR, or building a lot, one of the first things I do...sometimes THE first thing...is replace the crappy plastic horn with an aluminum one. The plastic used by vehicle manufacturers for their horns is way too soft...even the horns included with many servos can be better than the stock plastic horn. I would NOT recommend "waiting until the stock horn strips", as you're potentially 'inviting' disaster to happen.

    When I got back into RC a couple years ago, after a 35+ year absence, and bought my first vehicle (Traxxas Rustler 4x4), the first thing I did was replace the servo & horn (stock RTR servos are notoriously underpowered and/or slow). A friend, who had purchased a Slash, didn't bother. Lewis just say, I'm very glad I did...and, he's VERY sorry he didn't.
