For a few years I've had a hobby of building small hovercraft, which is one of the primary things that got me interested in electronics. After making a simple one several months ago, I've been wanting to make an improved one that can hold the weight of a 9V battery using propellers instead of fans.
So far I've made two test models:
which both scoot across the floor if I give them a push, but don't zoom across the floor spontaneously the way I would like.
The second model uses a lot of power (I think it ate a fresh 9V battery in 20 minutes), and I know that a rechargeable lithium 9V battery would be a more lightweight and (in the long term) affordable power source, so I hope to buy one soon.
I would appreciate any ideas for how I could increase the thrust.
