Default SK720 can't hold GAUI 200 tail in backwards flight.

I've noticed this evening that the SK720 can't hold the GAUI 200 tail in backwards flight. The tail gain is currently at 20% and increasing this value would cause a tail wag. I'm using a JR DS209G @ 5V. I'm using the latest firmware version (1.10). Here's my current settings under the Tail tab:

Base Gains and Rates for Tail
-
Control rate - 600 deg/s
Control Expo - 25%
Rate Gain - 75%
Hold Gain - 60%
Accel Gain - 1%

Misc Options
-
Lock Tail Gain - unchecked
Small Heli - checked
Blur Piros - unchecked

Cyclic Mix - 0%
Collec Mix - 20%

Start Accel (Left) - 20
Start Accel (Right) - 20
Stop Accel (Left) - 24
Stop Accel (Right) - 24


What adjustment(s) should I do?

Shorten your servo arm so you can turn the gain up without tail shake. You will will not get it all out. I have a Futaba 520 on mine and I still get a shake once in a whilein hover and I am using a 3 cell setup screaming the head. In flight mine holds super well.

Thanks for the reply. Unchecking the Small Heli box helped minimize the tail wag when increasing the gain.
