The trick is to have the exposure long enough to get some prop blur, while not ending up with camera shake.
Subjectively, the OS in the lens seems a little better than the SR in the body for these. Not enough of a sample to be sure yet though.

I was thinking of getting a bigma for my K7,are they prone to packing up?
I had the AF pack up on mine, shortly after buying it. It was replaced under warranty, and the replacement has been fine.
Prone? I don't know if it's any more prone to failure than anything else.

If they're soft, I'd say it's my technique, rather than anything else that's at fault.
But a tripod? For fast moving aircraft? Erm, no. Unless the aircraft path is extremely predictable, a tripod is impractical for most aircraft shots.
The main thing that makes it difficult is that unlike jets, with propeller-driven aeroplanes, you have to keep the shutter speed slow, since with exposures much shorter than 1/200s, you freeze the prop which looks rubbish.
Inevitably, hand-held shots with long lenses and long exposures will tend to suffer a bit from shake.
