Hi All,
Had a my firs Solo crash (in fact it was hard landing) yesterday and would like to ask community for suggestions why this happened
. Filled support ticked to 3DR, they responded very quick (almost immediately, taking into account that yesterday was holidays in US) and I was also impressed how Solo well handled impact. So, decription of problem (in facts, it's modified crash explanation I send to 3DR), video and crash logs (crash in log no.4):
I wanted to make video using cable cam, Solo flew into point A and I marked it. Then Solo flew into point B (point A was about 120m, wanted to make B lover, so descended to about 50meters) I also marked it. Pressed button to start cable cam and Solo suddenly started to descend rapidly, but It was not free fall. It took few seconds Solo to land. Also, saw battery suddenly dropped down from 64% to 0 on Solo controller and then back to about 60-63%. Solo landed quit hard, bounced and flipped over. As I can see currently, no visual damages (one of legs rubber end was pushed a little bit), but gimbal's protective foam is fitting very tight now, so maybe gimbal is little bent, but not sure about this. Gopro is OK. Made a test flight after inspecting everything: Solo, gimbal and gopro seem working OK from the first sight, but it was only short few minutes flight on remaining battery Solo failed with. Before this crash flight I saw green motor pod light right after take-off (rear right motor pod). Landed immediatelly, rebooted Solo: lights turn OK, started, made few short test flights: no warning again so went for a normal flight and this happens. This is second time I saw green light on same motor pod. Could not find meaning of one green pod light in both: Solo manual and 3DR website. Also rear left (not the same as with green light on it) motor looks a little suspicious to me now: as I wrote Solo flying OK, but it sound different than other three motors when turning by hand, I' suspecting bearings problems on it, but not sure it's crash releated. This Solo is almost new for a total flight time less than 6 hours.
Inspected logs, it's my first time I looked at logs, so not a lot of expierence here, but log shows double battery drain (from about 10-15A to 20-25A and even more) when stability problems happens. It leads me to conclusion, that motor bearing could fail, resistance increased and rpm's became lower, but Solo was trying to maintain stability and increase failing motor rpm's and this leads to significant current consumption increase. But I can be wrong, of course. Maybe it's some bug in cable cam software, because problems started after marked point B.
So, dear All, any suggestions?
