I finally had a chance to take this out for a flight after falling out of a tree last month. It was wobbling like crazy during hover, so I think I need to run an autotune. I'm not sure what else could be causing it as the props, arms and motors still look to be in good shape. Despite the wobbles it was a lot of fun getting back up in the air. I think I'll use my wooden props on my next flight.

I finally figured out the problem! It wasn't an autotune or my props, it was my VTX antenna getting under my prop wash. This was causing my entire rig to vibrate. I realized the problem when the antenna vibrated right off and it started flying smoothly. It's great to be back in action once again!

Interesting. It does make sense though. The antenna must have been going crazy to be causing the whole rig to vibrate.

I think I had my VTX so firmly attached to the leg that the wind current was causing the VTX unit itself to shake my rig. When I point the antenna another direction it flies just great!
