I've had a Swift for a while now with no problems. A few flights ago my motor power cut off during mid flight. It happened again today with a few flights in between with no problems. I run a 6s TP pack and it still had half a charge left. The speed control is a 80A phoenix, Century 600A motor, Futaba 2.4g radio and futaba digital servos. I had my first auto landing the first time....felt great. The last time I broke a landing strut....it was a crappy time to die on me. What could this be? It must be the speed control right? This happen to anybody before?

It could be a mirad of things. One of the guys at our field had something similar. After replacing the speed controller (which was the culprit) everything was okay. I suggest that you do the process of elimination and check each component. Also check for unsoldered connectors.

I'll put in a 100A centruy and see what happens. Maybe a component is starting to break down under load.

Are you using the on-board BEC or a seperate one? If the BEC heats up it will shut down the entire ESC.

Wiring...
Check your wiring from the ESC to the motor....I have had these break at the bullet connector... all still together, but if you move them a little bit, it would make and break connection...
Just a thought!!!! It is a process of elimination though....
Did it seem to happen at the same time into the flight??? If that is the case then I would look at the esc for getting hot.....

Good Luck..... Stan

+1 ^ for loose connections.

ESC settings? Second place to look at...specially the current limit settings.

ESC
Make sure you have all current limiting disabled...and also set your lipo cutoff to like 2.7volts per cell...if you have a weak lipo than can cause a shut off as well.

FWIW...I set mine to 3V per cell and use "soft cut off".
