Unstable with prop guards?

[cozzykim]

I have some prop guards, that I believe are genuine DJI, though bought S/H from ebay.

They make the Spark very jittery in the air, even with a good satellite lock before you ask.

Anyone else noticed this problem?

I have a set of aftermarket guards with fold out landing gear and I have no issues, and have never had issues with the stock guards either. Maybe try rotating the guards from arm to arm sometimes it can be hard to tell which way they clip on.

The DJI ones (if that's what they are, sold as such and look right) have the white dots marked on them that match with the props, so I must have at least swapped them round more than once for each pair of props.
