Default ALFA MiG-15 PULSING VIBRATION

On my Alfa models MiG 15, I've developed a resonance type of pulsing vibration at the higher RPMs. Anyone have any suggestions as to what might be causing this? Thanks!

Imbalanced fan, loose fan, loose motor?

Hey, THANKS guys! Upon close inspection, the fan had come loose a bit from the hub. By tightening the screw and securing it to the fan with a small square piece of Blenderm tape, I'm back blowing air smoothly.

Vit ... she is a nice place to fly, if they only made her with a 70mm fan for 4S. One of my pals got one and I and thinking of taking it off his hand, I did not really enjoy No. 1 as I made a mistake in using an El CHeapo motor, when it burnt access and replacement was a real chore.
