Finally did this mod and tested it today. Got almost to my max distance of 5038 meters at 4655 meters, and that was because of the low battery Smart Return. Could have canceled that like I did when I got the max range but was getting too close to a major highway, so I let it return. Tried a second run with my external battery this time but going in a different direction, but lost signal at 4489 meters going that way and the fail safe RTH happened. I should have pushed it back out once signal came back 3000 meters, as I have much battery left (72%), next time. Now this was with the 5.8 dipoles and the 2.4 in the legs mod.
