Setting up P2 today in Naza mode for the first time. Setup of switch positions was "standard" (top - middle - down): S1: GPS - Atti - Failsafe. S2: Off - Course Lock - Home Lock. Primarily I can see good use for Home Lock: being able to pull back on right stick and it will head back in a straight line towards the starting point even if that means it has to fly forward/left/right. After warm-up, green light, rapid flashing green lights (setting GPS lock), fully charged batteries, I tested out Home Lock (starting up facing North): I flew to the left (West, but still facing North) and set S2 to Home Lock position and pulled back (right stick). P2 started to fly to the right (East) straight towards me (still facing North). Exactly like it should. BUT, after 5 meter flying (while I was holding the stick position the same), it autonomously started to fly "true) backwards (South)...? This happened very abruptly, it just changed direction 90 degrees but itself. And, this very short correct Home Lock flying only happened when S2 was in COURSE LOCK position (S2 in middle position)?? When S2 was in Home Lock position (down position), there was no change from normal GPS mode behaviour, the direction of the sticks matched the direction the P2 was facing. So basically: "Home Lock" position didn't change anything. "Grid Lock" position acted like Home Lock, but only for about 5-10 meters and then it changed back to acting like GPS mode. 1) What happened ? What is wrong and what should be fixed? Extra info: P2 + Zenmuse H3-3D+GoPro - flew normally in GPS mode both before and after switch to Naza-mode. Tx + P2: latest updated versions PT software: Advanced > IOC > checkmark is set in "Intelligent Orientation Control" as I have read that it should be for HL/CL to work as intended. (See screenshots of the settings.) PS: during flight I have normal slow flashing green lights. I get yellow confirmation lights when I switched modes. But once in a while I got a single red flashing light in between the green lights. What does that indicate? Thanks - and happy flying.
