Hi, I am a new-be into the world of quads. Built a hover flip from scratch using the naza m-lite for the control system. Program the quad and it does fly, but do not know how the gps system returns the quad home. My tx is a dx8 and Spectrum 6 channel rx. The gps, altitude and manual are on a three way switch (flaps). I have done calibration through the assistant. I have read that there are procedures for the dx7, but do not know if I need to follow those or similar ones for the dx8. I do get a blinking green light when battery is plugged in, then it goes to solid green. When I switch from gps to altitude (failsafe) it gors to tellow/orange and in manual there is now light. Not sure what other answers will help unless you ask. Thanks for any help.
