Hi all,
I'm a seasoned fixed-wing pilot but heli newbie. I am comfortable with keeping it stable and flying around. I've also been starting to do some basic on-the-spot flips to get used to negative pitch control. I bought the heli used (specs below) and all went fine for a few flights. Now suddenly today while doing a flip (about 30m away from me and at 15m height) the motor seemingly just stopped when it was inverted. I managed to get it upside down again but it came down really hard and the blades + landing gear are broken and the tail boom is possibly bent a bit.
Specs Gaui X3 (belt version):
- Align Dominator motor
- HobbyKing Platinum 50A ESC
- MSH Brain (the old version) -> I'm running a Spektrum DX8G2 and just plugged a Spektrum satellite into the FBL
The battery was brand new and only 1 flight old and the cells are good.
My question now is: What could be the reason for a sudden motor shut down? It was the first flight of the day and I've flown two, three times in a row before so temperature should not have been an issue. It was also around 12°C air temp when it happened. Could it be that the MSH Brain is faulty and somehow turned off the motor?
Additionally - I'm not sure if this is relevant or an issue at all, since I'm new to heli flight dynamics - the heli had some wobbly moments on previous flights while doing warm-up circuit flying. I assumed it was the wind since it was a bit gusty but now that it crashed I'm not sure if the FBL could've been the culprit and it was a warning sign I did not see due to lacking the experience.
I'm now unsure how to proceed cause if any of the electronic parts are faulty I don't want to throw money at the model and fix the parts with a high risk of crashes or other danger possibly happening again.
Has anyone experienced something like this before or knows a way to troubleshoot?
Thanks a lot for reading until here and trying to help. I'd hate to give up on the joy of helicopters over this

but I had this situation happen to my 550, I couldn't find out what happened even after teardown 
Till I checked the batteries I was using and sure enough, in the connector was a loose solder connection 
I'm pretty good on pre-flight inspection but now a pre-battery inspection is in order too 
and don't give up on flying helis because of a bad incident
. As a pre flight, I check everything and mean everything even before spooling up. Trust your gut if something doesn't feel right. Last year I develop a check list for each of my birds for record keeping. It gives me peace of mind.
