I have a walkers g2d and g3d, I just filed down the gimbal to accommodate the slightly larger xiaomi yi.
Xiaomi yi in 3 axis g2d and 1 axis gimbal
This one is xiaomi yi on g2d
Thanks !! Jun Yamog the Video was spectacular, but there is a little wobble, is that due to the gimbal ? and can you post the pics of your Setup.
The V550 flights (1 axis gimbal) where you can see the rolls as only pitch is compensated has a post production stabilisation applied. This causes the wobble.
I don't have the photos of the gimbal, but here is some build notes
I don't have a good writeup of my f450.
