After making #1
, I was sure I could do better. Skimming smoothly over a perfectly smooth floor isn't really too much of an achievement.
So #2 was designed to hover higher and thus be able to tackle things like carpet or concrete on launch.
It does this OK. Once it is going it is fine, launching it is hard on rough surfaces, but it goes far better than #1, especially for it's size. It has a greater range of speeds that it hovers at, but the fins at the back make launching interesting
