Wonder if anyone else has has a similar issue, when I either manually trigger RTL or my batter fail-safe triggers and it switches to RTL mode all appears to be normal until the quad makes it's way back to it's home coordinates. At this point is just hovers at this location at the set RTL_ALT (1500cm) and never starts the decent. I checked an played around with RTL_LOIT_TIME from 0 to a few seconds and also set RTL_ALT_FINAL from 0 to a 15cm off the ground. No matter what I set it continues to make its way back Home and just sits there loitering at the RTL_ALT. I have to manually switch into another mode and bring it back down. I just worry if I ever lose my radio and can't bring it down eventually the battery will run out and it will come crashing down. Also other strange behavior is how long it takes to arm/disarm the FC, seems worse when trying to dis-arm than arm It can take a long time and I notice that my led typically blinks fast from red/blue while waiting for the disarm event and it feels like it takes forever to disarm. Isn't the point of a fast disarm to kill power to the motors immediately. I also noticed when running Tower that once it lands the disarm option on the screen doesn't show up once it lands. It almost feels like the FC doesn't think it has landed yet and won't power down the motors until it feels 100% certain its on mother earth. Trying to find some logs to upload..
