Dear All Arducopter users / experts,
Due to I am a NEWBIE to Mission Planner Telemetry Log File & in order not to happen again to any of APM users,
I am posting this INCIDENT with .tlog & .rlog files for any of the experts here to look into the LOG FILE,
whether :
1) It is a PHYSICAL DISCONNECTED POWER SUPPLY , eg: Wiring or DEAN CONNECTOR ? or .......
2) SUDDEN LOST POWER by the APM Power Module or APM2.6 ?
Note: APM 2.6 remained with power after crashed.

Appreciate with any responds & advises.
Regards,
Kenneth

Kenneth,
I would do the following;
1 Bring the foam legs in and more away from the props.
2 Mount the batteries under the chassis, side-by-side, not stacked.
3 Investigate the ESC's your using as it relates to your motors. Are they compatible?
Once the above items are corrected / investigated, test, test, test at low level altitudes.

Kenneth,
I cannot address the power loss issue. But I would never have my batteries that close to my APM. I had huge mag field issues doing that. Whats your compassmot in that setup?
Also, I've seen others use small foam sections on their landing gear feet, however as a practical matter, your foam is on the booms and blocking your props lift which I believe will lead to inefficiency.
I've had more than my share of crashes. I've learned even after a minor crash to check for any of the following;
1 Hairline cracks in props, chassis or booms
2 Smooth motor rotation consistant for all motors
3 Nicks or completely severed wires as result of broken prop impact
4 Loose components which could cause excessive vibration or wire disconnection.
