What kind of mounting tape are you using? You might consider a velcro strap around the FBL unit.

You probably will want to get a tool for leveling your swash, it's worth it. Checking cg is pretty easy, just pick the heli up by the blade grips and then hold it so the main shaft is parallel to the ground. It should not tilt forward or back. Checking for vibes is pretty easy. Take off main blades and tail blades. Spool up the heli and run it at different speeds. Watch for any servo movements. The littlest vibration can cause the beastx to think the heli is rotating when it's not.

Well, assuming you setup menus G, I, J, K, L & M ok for swashplate levelling, geometry and limits etc

Then you use parameter menu A to adjust like you would sub-trim assuming you cannot shift your battery forward for example to adjust the CoG forward to counter back drift.

Hope you get it sorted!

+1 and check your swash with a leveler.

If none of these work, try going into setup parameter E (stick deadband) and reducing it. I had a similar issue and one click down solved my problem. You may need to go more or less. It could also no solve your problem but try it if all else faile

Have you tried an underwire bra for better support?
