Default Where is the best place to mount full size VBAR sensor

Hi Guys,
Where would be a better place to mount the Full size VBAR sensor on a TREX 550E V2?

1. Directly on the mount area behind the swash plate or
2. Directly below the main shaft on the bottom tray.

I have previously mounted Mini VBAR on the mount area behind the swash plate on my two other TREX 550s and they flew great.
On my current TREX 550 V2 I am using a full size VBAR and I have mounted the sensor on the bottom tray directly below the main shaft. However on FFF I am getting tail wag.
Has anyone else experienced similar issue? VBAR and TREX 550 are brand new.

Thanks in advance.

The least amount of vibes are on the lower plate but the frame flexes a bit. I added 600 boom braces and cut to fit and it stiffened it up. The stock is to flimsy.

Either location is OK if you can sufficiently dampen vibrations. Neither location has any advantage from a sensing standpoint. As I pointed out to another member recently, all parts of the heli rotate at the same rate; the only difference is in the amount of linear movement of the sensor, which the sensor can't see.

Experience is something you obtain only after you need it.
I wouldn't mind social media so much if it didn't involve people.

Mine is mounted on a kde gyro plate above the servos at the front, main unit on the tray at the back. No probs at all the heli flies really nice.
