I think i'm ready to increase the control throws on my arrow but I noticed that the other two holes in the servo arm are to small. Can I just drill them out to fit or is it not designed to be moved from the factory setting?? Thanks,

I used a 1/16 drill bit to open mine up,it works fine with a little more throw.

You can use a sharp drill, turned by hand, to enlarge the holes. Most control horns seem have undersized holes. I think it's because there are so many different linkages available they want to be sure the holes are not too big.
