If you have a tail issue from vibration then fix your heli .

+1. Those vibrations aren't ONLY affecting your gyro, they're affecting your servos, Rx, batteries, wiring, etc..

You just don't know it until they FAIL...Then you call Futaba or JR and complain to them about their junk equipment....

Maybe an explanation of why this thread was started would be in order...I am still lost on where the problem is. I may be wrong, but it sounds like there may be an underlying unresolved issue with a heli and gyro. If there is enough vibration to interfere with today's gyros, then something else is wrong.

i think a windy day is more of a problem than vibration. out all the things in the hobby that are a pain in my toe, drift from vibration is not even on the list. even when i was green behind the ears, i had no problems with the tail.

My long and detailed post is saying the same thing. Vibrations isn't really a problem for the solid state gyros, at least operationally. Vibration is a problem over the long term when it comes to everything.

All vibrations can not be eliminated, only mitigated.

I don't know what gyros you're buying, because all my helis work fine including my nitro.... This challenge to manufacturers seems a bit silly. Most good gyros work fine, even on 90 size nitro. What you should challenge them to do is build a gyro that any nub can install and use

If the gyro manufacturer builds a gyro that is impervious to vibration what about the rest of the equipment? In my way of thinking, if the heli isn't smooth enough to let current gyros do their thing, the rest of the heli is going to suffer equally. The gyro is the only thing on the heli that will give you enough feedback to let you know how poorly you really built the mechanics.

The gyro is sort of a litmus test for the builder of the model or BOM. If you suck at building, it will tell you how bad you suck. If the engine shakes, it will tell you how bad it is shaking.

Be thankful you are not using an old 153bb, or any of the other old mechanical gyro's that used the tiny little wires that went to the motor. I broke a few of those back in the day even on smooth machines.

Vibrations loosen and wear parts and carbon fiber blades can kill a man in a second.

Fix your heli, the mainstream gyros are fine.

My heli is fine. The engine has been fine-tuned over many many flights. I am one of the few who actually gets out the dial indicator and dial indicates the engine every time I take it out and break it down. The build is meticulous.

But on a nitro we are still dealing with a single piston moving up and down at about 18,000 rpm. Nothing, absolutely nothing we can do can eliminate the vibrations induced by this single piston engine!

Man, if you're having vibration induced gyro problems then your heli is not fine.

A gyro drift is an indication of a bigger problem such as tuning, setup, bent parts, wire routing, etc. It's a feature

It's not drifting.

When my electric heli is in a hover, it practically looks like it is sitting on a bench. The Nitros don't look like this.

And it is not only my heli that I am refering too. It is everyone at my field. Like I said, we all just "put up with" the fact that the nitros don't sit in the air as rock solid as the electrics.

It sure would be nice if we could close the gap.

Ahh, I completely agree, but you're right, won't happen with a single piston engine.

I like Eco8gators elaboration on this idea too:

Vibration Isolated Electronics Mounts

There are 2 very cool things I like about his idea off the top of my head:

1. This opens the field to many more companies, heli kit manufacturers, and aftermarket companies. The more vendors who are searching for a solution, the better options we will have.

2. By not limiting this issue only to gyro manufacturers, we could use said isolated mounts for our RX, our regulators, our FBL sensors, etc. Also, it does not limit us to a single gyro company. If company x manufactures the best Isolation Mount, but we prefer the Gyro from company Y, then we have the option of buying both.

Yes, this is very good.

gyros
Rock,you rock because I was thinking about the same thing about these gyros. Gyros need to understand certain vibrations are engine produced and be senstive enough to distinguish between pilot input and engine vibration.

If everyone at the field is having the problem, something is wrong. I can show you several different nitros that have no problem standing still in a hover (hands off even). Electrics are a lot smoother and thus maintain smoother stability, but the nitros can do the same thing when set up properly.
