You might be referring to this:

However, the shimmy I keep hearing about is at lower speeds, taxi usually. I had to keep rolling on those flights due to another guy in the pattern.

And as I recall, YOU offered to trade your 430 for my 650

Default Thanks Bryan

Look at 4:18...the twist on the landing gear....even though this pilot has a habit of greasing them in. This may be what caused Lan Vinh Do's issue?

Back to looking for a 650....Never a deal till both parties agree and exchange.

And 9:05-9:08

I see what you are referring to, but I don't see it as a twist, more of a flex as the tires touch and the slight resistance to get them turning. The consensus on the original post was that it is a harmonic vibration issue that occurs at low speeds. We want them to flex, we just need to figure out a way to adjust the speed at which they shudder/shimmy. Anecdotal info seems to indicate that the gear braces help.

Default Maybe my vibration was worst

Hi
I agree with everybody but i think i had a very BAD vibration. The one that you think that the airplane will fall apart or the one that make you inspect the engine mount and firewall because you would expect to find a crack.
I had a rv-7 before and i had some vibration that i was able to deal with but in the rv-10 it was bad. It begin with just a little shimmy like in my rv-7a but went worst and worst to very BAD.

With my upper gear leg bolt loose, with time, i think i would have a structural failure. I just want rv-10 owner to check these bolt if they have bad vibration.
It was hard to notice when moving the gear leg when the airplane was on jack but it was there. Not forward and backward movement but rotation.

Now i can live with the really small vibration that i have. I may add stiffener if it bother me but i don't think it can do anything to my airframe now.

So in conclusion, I don't say that i found the vibration problem of all the RV but i found mine and i am glad because i am sure it would be dangerous with time.

We don't manufacture these in house. Another RV builder makes them for us, and we resell them for him.

Take a look at our website in the RV section, and you will find the gear leg stiffeners .
Just installed these stiffeners and it made a HUGE difference. No more main gear shake.

Has anyone installed a nose gear stiffener? I?m getting a little shaking on roll out out of the nose gear.
