That is exactly the horns I was refering to.I could get by using the 5/8 long horns. But by using the 1" or even the 1.25" horn it would allow me to either mount them in a more structurally (sp) sound spot. I guess what I was wondering the most was, does it give the servo more leverage to mount the horn further away from the hinge line? Instead of theservo having to short moment arm ( relative to the hinge line) , it could have a longer moment arm. These are relatively large control surfaces, so I thought any leverage help would be a good thing. I hope this made sense.

Thanks for all your help,

Paul
