I had a pretty serious crash on Saturday after a few minutes of flying. I'm a newb at all of this, but I was able to download the logs and graph them after the flight trying to figure out what the heck happened. Towards the end of my logs the graphs clearly say Err: Failsafe_Radio-1 and Err:Failsafe_Radio-0. The distance of the quad wasn't all that far from the launch site so I can't understand why this would happen.
The worst part was that the quad went about 200-250yrds down field and crashed pretty hard instead of returning home; breaking all four props, motor mounts, gps mount and battery holder.
I guess the RTL command would be the reason I lost control of the quad. My biggest question is why would it fly so far away and crash so hard with what appeared to be a GPS lock before the initial take off? Also, if anyone could examine the logs I have attached could you tell me if anything else happened maybe that I need to fix or debug??
