The Spark propellers can move about in the carry bag, and I am always worried it might get scratched or bent. Especially when I stuff the propeller guards in the bag too when I first got my Spark. You can buy rigid plastic thingy to hold it in place for a few dollars on eBay.
But I came up with a simpler solution. A couple of piece of paper should do it.
Cut 9cm x 15cm, fold twice along the length to get a 3cm x 15cm strip. A bit of sticky tape. Voila.
Once it gets worn, just make a new one. You can also get coloured paper to match the colour of your Spark.
