Specific Servo Horn

[martinpal]

Can someone please recommend a servo horn / screw for a futaba that will specifically fit the Predator perfectly?

I am currently using an associated horn and it fits well but the screw supplied to go through the ball gets very loose.

Thanks.

i dont use the T.Tech supplied ball - i use a ball joint and a ball cup off my B4...no problems encountered with this setup at all.....

I actually tried this with the Associated servo horn but it causes the linkage to be too far out causing stress on the linkage arm. I think it's due to the associated servo horn being a little sthicker at the top.

I guess the answer is to use a standard futaba horn (thin?) With the ball stud and ball cup from a B4?

Here's a link to some servo horns, do you think these will work ok?

you can always run the ballstud on the "inside" face of the servo horn, so it over the servo...

I use one of these, they come ina pack with 4 inserts to suit any servo.

if you use the kit ball just drill out the holes a touch to get the screw through

I always use the Fastrax ones (which are KO copies I think), big, beefy and strong.

Don't worry about opening up the hole in the chassis a little if needed.

I also use B4 servo mounts to move the servo a little closer to the centreline of the car.

Cheers,

Thanks for the advice on this, I ended up getting a horn similar to the fasttrax one, but made my ofna.



The steering is much better, no more flex on the arm and the screw no longer falls out

I did have to drill the second hole just a little bit to get the screw to fit as mentioned above.

It's too bad the kit doesn't come with a servo horn.
