It does look like to much down thrust in the picture. Normally down thrust runs from 1 to 3 degrees with 2 degrees suggested for starters on most of my aircraft. Since this is a new ARF on the market I would suggest you contact SIG either on their web site or by phone. Maybe this is what they intended then again you know how new ARF's can be with quality problems, not trying to scare you but I would contact Sig and send them a set of the pictures you have posted here.

Good luck
