VTOL Take-Off Issues (Possibly)

Hello,

I’m working on testing a VTOL Tricopter/Flying wing and I’m having issues taking off. As I increase my throttle I seem to get stutters in my front two tilt rotors. I’m not exactly sure how to go about solving this issue but I think there’s a vibration issue with the tilting servos. If anyone can take a look and point me in the right direction, that would be great.

Thank you!
