I've been helping my son learn to fly with a FT Simple Cub on power pack B.
He nosed it into the ground after barely missing it the first time and stalling. Maybe 10-20ft height. Maybe at a ~70deg angle.
The motor seems to still be balanced just fine. There's no play on the shaft or outrunner.
When I'd spin it by hand, there was a faint rattle. When I'd spin it up anchored on the ground, it went away. But we'd hear it rattling most of the time in the air.
Flight times and performance don't seem affected. Again, everything runs smooth and balanced, it just doesn't sound like it.
I opened it up, blew it out with air, and inspected the windings etc - nothing out of the ordinary (that I could see, anyhow). I wonder if it's a slightly damaged bearing or something?
Is it worth the time/sweat to try and source and replace a bearing on one of these motors? Or should I just fly with it until it becomes a problem?
I replaced the motor already. But if it's good to fly until it gets much worse, maybe I'll just make this the "trainer motor"
