FAQ
Can I start small and expand later?
Yes. Start with core props and buy a controller that gives you one clear expansion step for next season.
Should I use 5V or 12V pixels?
Both can work well. Many beginners choose 12V because power distribution is often easier in larger yard layouts.
How many spare pixels should I keep?
Keep at least 2 to 5 extra strings plus spare connectors and fuses so you can repair quickly during show season.
