    Mike, I didn't want to run out of room on my last message: Sources of 2-p-r shake are:
    friction in teeter bearing, axial play in teeter bearing or pitch pivot, looseness or resonance in cyclic control linkage. Teeter bolt should not be tightened like you would another gyro - it has combo bearings (thrust and axial) to eliminate axial play source of 2-p-r shake - that could be damaged if tightened too tight. First thing to do is be sure you are seeing 2-pr or 1-p-r shake - sometimes not apparent, but can be ID'd easy. If I can help, email - Greg

    Hi Mike,

    I don't respond on the forum any more - too much time and stress. But, I noticed your thread on 2-per-rev shake. I also noticed Chuck's comment about shake of your MAGNI rotor. I didn't see where you were talking about a Magni. Which Magni are you talking about? Magni rotors should ahve no shake - and 2-per rev shake is particularly abscent in Magni rotors. If it helps, see my article:

    Email me at gyrogreg@ldd.net if I can help you resolve your problem. 2-per-rev shake has specific sources, and I would want to help resolve any rotor shake issues you might have that should be corrected.

    I may have something you can use for the CG of the rotor.
    I will send it personal email. Send your email address.
