I know, that the RevoMini is out of production and I don’t know, how many are still around. But in my eyes, that FC is ideal for small airplanes, I my self have four of those.

As a tip, it’s better to use an F4WSE FC, which has a footprint of 4x2 cm and has significantly less cable clutter than a RevoMini: https://www.aliexpress.com/item/1005006466804229.html
