Just built a new X50 nitro FBL with the Redline 56 and main blades
After a few test hovers I had the tail vibrations like I had read from others.

One suggestion was to check to see if the start shaft is rubbing on the crankshaft transferring vibes to the airframe. Mine was. I took off about a 1/8in from the engine side and now all is well.
