Hey Rover, I got exactly the same setup, same plane etc. I don't know what it is about that airframe but it shakes that back end like no tomorrow. My hoizontal stab came loose on mine when I tested it for the first time. I've been flying this combination for a over a year now and I can tell you that it still vibrates (on the ground) when that motor is throttled up. I guess its fine in the air or mine would have vibrated apart by now. Never had a airframe vibrate like this one. The gear on this bird is very weak, if you have not done so do yourself a favor and get a carbon replacement. And, make sure all your servo arm screws are secured with silicone. The vibration on the back end will loosen them up over time. Fairly decent plane but its hard to see with that color combination IMO. Jerry.
