The following tunes are good recommended base tunes for your TWIG builds. Since are designs are universal kits that can be built with so many different types of flight controllers, motors, props, and other components, each build will vary. We suggest flashing your flight controller to BETAFLIGHT firmware version 3.5.7 as this is the best firmware we have found for micro style quad builds. Although there are new firmware being introduced regularly, we have found that version 3.5.7 is currently is the best performing we have found with most micro style builds. Feel free to also join our "TWIG Builders" FaceBook group page to ask for help and share your tunes. The "TWIG Builders" FaceBook group was created to help others and share your custom builds with others.
