Horizon mode provides self-levelling when the sticks are centered and the quad is close to being flat, but flies like acro at higher stick angles or when the quad is steeply angled. The 'self-levelling' strength, when the sticks are in the center region and the quad is nearly flat, can be as strong, or as gentle, as the pilot likes. The angle of the frame at which there is no self-levelling can als be adjusted. With the default settings, flips and rolls to be performed, and with a bit of tweaking, inverted hangs are possible. -For more information, and sample configuration snippets, see [PR 12231] (https://github.com/betaflight/betaflight/pull/12231) +For more information, and sample configuration snippets, see [PR 12231](https://github.com/betaflight/betaflight/pull/12231) Thanks @ChrisRosser and @ctzsnooze -## 7.
