Problems with 250quad

[Terryfrank84]

hi guys, just finished building my first 250 quad and I've set everything up as videos and instructions have said. But when I take off it is juddering quite a lot. Is this normal? I'm using a cc3d on open flight of this helps.
Thanks

Sounds like you need to adjust the auto level settings, and balance the propellers.
