A tip for flying it indoors 
Besides clearing away any obstructing furniture (if you have pets place them in a separate room!) the one most important thing to remember when flying Spark indoors is to use the prop guards. Spark’s prop guards are pretty ingenious. They look tricky to put on, but basically, all you have to do is lift up the little latches so that it opens up the slot and you can see an opening. One by one slip them on and rotate them until they reach the end of the rotation. Next, clip them on so that they are firmly attached. Prop guards are very useful when PalmLaunching and PalmLanding.
