+4. If coming from RF1, please setup your helicopter from scratch for RF2. Follow the instructions on the website!

+## Support
+
+The main source of Rotorflight information and instructions is now the [website](https://www.rotorflight.org/).
+
+Rotorflight has a strong presence on the Discord platform - you can join us [here](https://discord.gg/FyfMF4RwSA/).
+Discord is the primary location for support, questions and discussions. The developers are all active there,
+and so are the manufacturers of RF Flight Controllers. Many pro pilots are also there.
+This is a great place to ask for advice or discuss any complicated problems or even new ideas.
+
+There is also a [Rotorflight Facebook Group](https://www.facebook.com/groups/rotorflight) for hanging out with other Rotorflight pilots.
+
+

+
