I copied this post from your duplicate thread and will delete mine from the other one.

What I try to do is max out the end points and use the closest hole on that SWB arm and furthest hole on the DA throttle arm to get full throw of the butterfly. I always have my servo arm at a right angle to the servo case with the throttle butterfly at 50% of its full rotation...at half throttle stick. This usually gets me a very good feeling thottle using all the of the transmitters resolution (full ATVs). It makes the throttle feel smoother. With that SWB arm you may not be able to get close enough in. You may need to drill another hole or use a smaller servo arm....I'd have to see it to be sure.

I just went to grab my DL-50 that was setup on my 30% Edge (going into my new 30% EF yak). This setup used Hitec 1 inch arms with the 4 holes in them on both sides. The push rod was on the 2nd hole closest to the servo, 3rd hole closest to the throttle shaft. I think my end points were not far enough out though. Only about 100/100 out of 140/140 max. I really should have drilled a new hole in the middle of two on one of the arms but was too lazy.

PS: Also ignore that 1st hole closest you see on my servo arm, I drilled that one myself. The pushrod is really on the 2nd hole. not the 3rd (and someone always catches the stuff that doesn't make sense in my posts).
