When I originally ordered my Cheerson CX-20 I ordered 2 sets of prop guards. I was not yet confident in my flying ability and my thinking was that I would want to protect the props. Unfortunately the order was very much delayed and by the time they arrived I had already flown my CX-20 quite a number of times and had become used to flying without them. I had also read many comments discouraging one from using them as most found them to negatively affect performance. While cleaning my work area I came across the prop guards again and I decided to fit them and test them for myself. In short I found that they "calm down" the wobbles and even though they do slow down the CX-20 a little the performance is not poor. For now I think I will keep them on as I discovered that they reduce incidents of VRS too. Here is how I fitted the prop guards and 2 flights I did which shows why I cam to this conclusion.

I have damaged a 9443 prop on body alone before trying the props and I have heard the 9443 props touch during aggresive manouvres in wind, so be warned.
