Here is the recipe: Raptor 620 stretched to 90 - 10s2p a123's; zpower z50a-800; 700 mains; raptor 60 tail blades; cc 85hv esc; hv BEC; 401 with 9254 gyro; JR 9303 tx; 770rx. 0 pitch @ 50% stick - Hover speed with an extra 5lb payload = 1750. (governed)

The issue i have is that in normal mode a slight movement of the throttle will cause the tail to twitch about 45 degrees. The twitch is annoying. In idle up the tail is solid. Where is the likely cause of the tail sag? I used the setup routine suggested by Clint (thanks - what a great help with my first ehelo)

This thing flies great in the governor mode; gets 9 minutes with the payload. Thanks for any suggestions.

sounds like the differance in rpm from Nor to Idle 1 might be the problem,what is TC seting at 0 stick in normal, idle 1??????

Too much gov gain can cause this on the HV85.
Lower your governor gain using the castle link (only way you can).
