Default Trex450 SE V2 FBL conversion specs?

Where can I find the manual for the FBL 450 in order to get the proper link lengths and which servo arm holes to use? All of my geometry is correct, it's just not flying how it should be IMHO.
I'm using a Micro Beast unit on my SE v2 and it's def not flying like my 500 FBL does with the same unit.
+ pitch pumps makes the heli want to roll off to the right. - pumps and it rolls left. Piros are not stable and in control. The heli actually is flying like it has a FB.

I'm using the pads the Bx came with. Don't know where vibes could've come from. It's been smooth as glass all this time.

I just moved the Bx up onto the boom clamp whee the orig gyro was. Hopefully get a test flight in later.

Do you know what hole would be best to use on the servo horns? Using Align DS410M's

Everything I've read indicates that the tape that comes with the BX is not great and a lot of issues have been solved by using the 3M tape (4011 or 4010, same thing, gray tape with red backing)

What about the 3M clear tape with the red backing?

Not sure, I ha some gray stuff and used it. I guess it depends on how thick the clear stuff is.

The BeastX tape works just fine. Moved the unit up onto the boom block and all is very good now.

Also found the reason for the right roll on + pitch pumps. Wait for it....I must've turned the Aileron swash link 1 too many or not enough turns when I was testing, therefore, crooked swash my bad
