RC CAR DRIVING ON THE CEILING (Patreon)
Content
Hi everyone!
This has been one of those projects that I thought was going to be much easier than it ended up being, the benefit of that is that I know much more than when I started.
SPOILER ALERT: WATCH THE VIDEO BEFORE CONTINUING READING.
1st thing learned: Battery voltage is not directly proportional to thrust gained. 6S batteries produce much more than double the thrust than 3S batteries (on the same setup).
2nd thing learned: Props have to be mounted taking into account flow direction. In this episode I used quad props to push instead of pull without flipping the props at first, and that caused a 66% drop on efficiency and a 800% increase on noise produced. As a corollary, props have a slight taper that fits perfectly on the motor shaft so flipping the props requires a bit of extra force and worsens the balance of the props a bit.
3rd thing learned: Flat, unobstructed ceilings that can be reached with a ladder in a public place without a road below are a scarce resource. I'll add testing location to the checklist for future projects.
I hope that you liked the project, please leave your thoughts down below.
Thanks!!!
