magic smoke from Tunigy B3656-1800 on 5 X 6S

Had several flights today with the Starmax 90mm F/A-18 and its cheap Turnigy B3656 1800kv motor bringing the total flights well over 60. I've had one external ESC smoke months ago before I located its replacement inside the duct for better cooling. I was at home running my batteries down (in the plane) for storage having fun blowing leaves out of the gardens. On the 5th battery near the end of its capacity the motor let out its last gasp with magic smoke. I was thinking it might be the ESC but it was indeed the motor.
The heat must have built up without the usual cooling down period it would have had between flights...
Another lesson (don't run battery after battery without some cooling off period).
Although this motor failed I think under normal use it would have lasted much longer and makes a decent motor for little money.
Zen thinking * It's rebuildable till it fits back in the box. **

Eric, you can actually buy a purpose built leaf blower at many different hardware/garden centres.. I thought a guy like you would know that!!!!! I suspect you were attracting some stares with a "Hornet - shaped" leaf blower. Next, you'll be trying to make retracts serve double duty as a beer opener. Anyway, you have a teenaged son why wasn't he doing the gardening?
Best Regards
