Finally had the time for the next flight. I increased the Roll and Pitch gain settings as the first two flights were quite sluggish to control inputs. I was hoping to complete the "Manual" mode trim setup this flight but I continue to have too much starboard roll for the trim setting on the controller.
- The gain setting increases helped (some) with the sluggish control responses.
- In addition, I found the control surface hinge lines to be far too stiff. (I cut relief sections to reduce stiffness)
- During the build, I laminated the wing, tail, and control surfaces to stiffen the airframe
- Manual mode trim was also affected by the laminating material, which caused a slight twist in the starboard alerion.
- Reheated starboard control surface to improve the shape, next flight will tell

Takeoff weight of my Ranger EX 757-3 = 2700g
The 10X6 prop runs the motor near its recommend maximum, but I only use full throttle for takeoff and have not encountered any thermal issues (yet). I did not go back and try the original motor with the 4S battery, that may be more than enough to get good performance from the airframe!
