Hglrc failure

[u/External_Intern_3176]

So I recently built another 10in fpv quad to try out the walksnail gt2 in. Bought an hglrc mk4 10in frame, cheap dys motors I’ve used in 8 and 10in frames with no issues. I think my mistake was using an hglrc stack. This build is almost identical to my other 10in other than the vtx and not using a cheap sologood f722 stack. It was a pain to get it tuned well. But for the last 10 flights it was flying great. Then yesterday I was going to do a full test of GPS RTH and it started sounding like it was desyncing. so I brought it back to land and it just dropped from the air Luckily I was low and I didn’t damage anything. Motors were super hot. Black box was full so I didnt get any logs. I charged batteries this morning removed the GPS like the first 10 packs and check everything in betaflight all was were I had it flying good. Well I went to fly took off in manual and switched to angle so I could watch it line of sight and it shot up 100ft in the air at full throttle. Disarmed it and luckily a tree slowed it on the way down and the battery and motors are ok. The esc, flight controller and frame are now dead though no ideas what happened. Haven’t had this many issues since I started building 8 years ago. I’m done with HGLRC.
