Coming from betaflight, I've found the Kiss Ultra system much easier to use and the flight quality better. Plan to use for all my future builds. I also appreciate being able to find quick answers for questions on their discord.
Always so reliable, I recommend !
I didn't know anything about this company before. But one day, I bought a ready-made BNF drone. It was assembled using components from KISS. When I decided to build a few more drones for myself, my choice was clear. Only KISS! And the team's work confirmed it was the right choice!
Best darn flight controller period. The Ultra Team, founded by the Commander, is a well-curated community where you can delve as deep as you like. The focus is on how-to guides, support, and general discussion. Discord is the best place to connect, and it's no longer a private space.The ULTRA TEAM has always been there to remind me: KEEP IT SIMPLE, STONER! lmao.The Discord is darn near close to 24/7 live support as we all tinker at different times. The Discord is everyone-friendly. I've made some great friends.
Best stuff on the market
