You might want to drill the servo arm ballstud hole opening a little bigger - Its aluminum - so the strength will still be there.

Yeah you need to drill 1 hole to 3mm.

I wouldn't recommend using only a alum servo horn without saver. It will kill your servo prettty quick.

Hi

Thanks for your replies. I have now drilled the hole, and it works perfect.

I know that I have to be carefull without the servo saver, but now I can drive a little bit untill I get one.

Thanks for your help guys.

I had to mod a couple of them aluminum horns. I drill and tapped it out to accept the screws.

Glad we could be of help....
