### ⭐⭐⭐⭐ Must use low esr capacitor to clean video feed
*by K***S on August 14, 2018*

Great vtx so far works perfect with smartaudio on dys f4 mini fc. I gave it 4 star tho because being powered from 7+ you can't use a 5v pad to power the vtx. Has to be directly from lipo so you have to add a low esr capacitor to get rid of ton of video noise. After you add the cap it's a great vtx
