Vibration at low head speed

Guys...on one of my X5(version1) as I am coming in to land I saw a noticeable vibration at 1800 rpm. Looking at the diagnostic chart I can see both front to back and side to side spikes. I do not see any issues at 2200 rpm either on the diagnostic chart or during flight. Any thoughts?

Vibrations at 1800 rpm.
More than that... Nothing...

You need to check:

Gear interference...
Unbalance spur...
Bend shaft...
Unbalance blades...
Unbalance rotor...
Boom supports...
Gyro mounting...
Tail Push rod loose...
Canopy post grommets loose...

/Saludos cordiales,

Thanks for the updates. I will check on these. I will say that the main blades are pretty tight so I will be checking on that first. Again thanks.
