Don't order the cheap copy ones on ebay! They may be cheap, but that is for good reason! Don't go cheap on important things like this...a saving of $5 could cost you a hell of a lot more when this one inevitably breaks (I'm not saying all Chinese parts are bad...but you understand what I mean).

Seriously, for $3 more you can buy a Dynamite horn from your LHS if you want cheap... And it won't take four weeks to get in the mail.

the arm comes with plastic inserts. Kinda defeats the purpose.

Looks like junk.

I use Hitec servo arms only. The arms that come with 7955 servos are tough. They include an aluminum horn as well, but I've never used it.

Dubro makes good horns.

That's why I only use the plastic Hitec arms.

I think the blue aluminum arms are for airplane applications. I think the plastic has some give that keeps it from stripping, while the aluminum arms have very little give. I'd bet, that over time, the plastic Hitec arms are more durable than the better aluminum arms out there.

I also think that Alu arms have a hair of play that allows them to strip out the spline over time. The plastic arms are molded a little small and stretch over the servo shaft. No play, no stripping.

in regads to servo, I prefer an alum built with clamp. That said, it'll eliminate play and of course, the stripping.

I use this and it is okay up to this very day, http://www.amainhobbies.com/product_...-Red-24T-Hitec
