So I finally activated S2 switch in assistance, tried it out and it does work some... Could be the 20 degrees, 30 mph gusts, today messed me up some, but I had to try it out! S2 mid position, course lock, worked as advertised. Sweet. S2 down, home lock, made it fly some random way - maybe due to wind gusts; guess I have to retry in calmer weather. Tried RTH again (S1 bottom), and it STILL changes slow green blinks (11 sat) to yellow, and goes who knows where! I tried this from 30 ft hi; I tried setting RTH height to 20ft, 50ft, nothing - it never changed height when I flipped S1 down. Just changed lites to yellow and went random direction. HELP! What am I obviously doing wrong? I am scared to turn off the controller to see if loss of sig does a good RTH.... I really should be able to get a RTH from S1 down, no?
