How are those beads going to migrate to the sidewalls to counter the dynamic imbalance? Centrifugal forces at typical wheel RPMs are not...

Yes. Those legs rotate 90° as they retract so as to fit better in the aft nacelle. The mechanism that does that is elegant in its...

When I was still at the flight school I wanted to build something similar. Fun, but with a training aspect to it to justify it. It would...

So, hard landing that collapsed the gear.

MT composite props. MT uses wood cores on theirs.

How many of the dynamic-balance skeptics here have done a dynamic balance on a nosewheel to see if it stopped the shimmy?

Crash? Looks like a simple gear failure to me.

Retired now. Not balancing anything.

I've seen them on big-tired pickups. I think that mud stuck inside the wheel might be the reason for those. That can throw the balance...

I built this one: It has no fancy electronic sensors in it. It uses the same principles as this antique dynamic balancer: I had...

I should also mention: while the wheel needs dynamic balancing that it probably won't get, that shimmy damper has to be full of oil...

The root cause is always dynamic imbalance. Always. I have dynamically balanced shimmying nosewheels without touching the worn stuff you...

Uh, yup. OK. Using nicotine to cure cancer. How's that?

Vibration from taxiing over rough ground does that, along with nosewheel shimmy. There isn't anything you can do about it other than...

There are exceptions, Poor engine grounding, even a small fraction of an ohm, can cause overreading of electric oil pressure or...
