Does anyone know if there is a trouble with these servos?

I've been told that they are being called back (in France at least) but I could not find any info about that?

I have nearly 50 flights on the ones installed in my SM F16 without any trouble, so it might just be a deffective batch, but I'd like to know which batch?

Thanks
Florent

Nothing we are aware... great servos...

NP with mine: 55 flights.
