Status: offline 		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!

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.
