In this video i want to show you the basics of ballasting a modern rc glider and especially f3b planes for contest flying. F3B is a competition class where the pilots of rc gliders compete in three different tasks. These are Duration (10 minutes of thermal flying with a spot landing), Distance (flying as many 150m legs as possible in 4 minutes) and Speed flying (flying 4 150m legs as fast as possible).

Chapters:
0:20 Intro
1:00 Where do I put my ballast?
1:37 Where can I get my ballast?
2:18 What kind of ballast should I get?
2:42 How can i tune the cg of my plane?
3:20 Why should i move the cg?
4:07 How can I optimize the cg of my plane
4:52 Is a heavy glider a better glider8?

For more info on F3B check out my other videos and also the playlists on my channel.
