Bring back the old flywheel gyros,they weren't as sensitive as piezo gyros.Piezo devices detect movement to molecular levels therefore they will respond to vibration.The clever bit is designing the electronics to try and filter out vibrations and make it respond to angular movement only.They are used in seismometers as well.

More time and money invested in improved algorithms would undoubtedly solve the problem for most. Sadly, it is us lot that need to spend the time fine tuning the mountings to compensate for inadequate software.

Vibration Isolated Electronics Mounts
A better approach may be a whole airframe vibration suppression system. Active systems are in operation today on aircraft. One specific is the CV-22. A active system reduce overall wear and tear on everything and it is much easier to integrate than a bunch of little suppressors.
The problem may come with weight and power consumption. There needs to be sensors and servos systems on all axis (x.y,z). Each of the servo or "dampeners" will need to be slinging weight 180 out of phase of the noted vibrations. The environment we are talking about would require the dampeners spinning at a fairly high rpm. It is possible but it would be pretty expensive to develop.

Gyros need to be able to detect tiny movements , so they will naturally be effected by vibration . What we need is helis that don't vibrate !

At the end of the day , it gets dark .

Helis that don't vibrate, you'll be in for a long wait.

Remove the air from the equation and you'll get rid of the numerous aerodynamic sources of vibration, then all you have to worry about is the mechanical ones

The solution is for the gyro companies to offer a software interface to the gyro that allows the user to tell the microprocessor to ignore certain frequency's ( noise ). Maybe offer a plug in gyro datalogger that allows you to record all frequency's sensed by the gyro during flight. It would be easy to identify the noise frequency and then tell the gyro to ignore it.

Smooth solid gyro response regardless of application.

heres one for one of you to r&d and patent, dampen the electronics in the case with magnets (that repel each other), do this on x,y,z. If you use the right magnets and get the correct dampening (ie: strength of the repulsion,(spend many, many late nights, early mornings and franklins)), the gyro sensor will be isolated enough not to pick up vibrations, but will sense all movement in all axes. Air, or another gas is a very good insulator. Once you get that figured out, then you'll have to magnetically shield the electronics so the magnets do not affect anything. Then you'll have to figure out how to get rid of the heat in the electronics.

Get all that done and you'll have a levitated sensor that shouldn't pick up harmonics (sort of like the mag-lev trains). Then spend 10's of thousands paying an attorney to help with the patent process.

Sounds fun, but i'll stick with my vbars

Take the original post & apply this to Vbar sensors as well! I've done everything but still sometimes get slight drifting in my 700E's.

IMO Mikado needs better vibration filtering programming or algorithms. I had Spartan DS760's before with FB and they never drifted.

I'm not sure if the manufacturers are listening!

Saturday morning I flew my helicopter in my pajamas
How it got in my pajamas I'll never know

There is one part of this you gotta consider. ALOT of the technology used in our gyros comes directly from the military - missles, drones & autopilots. Since these are mostly turbine powered & alot smoother than our helis, I wouldn't hold my breath waiting for the manuf to refine his product for our small market segment . . .

Helicopters that dont vibrate and a gyro not susceptible to vibrations. GOOOD LUCK. When you achieve both of those tasks then tell us. Stop getting futaba, obviasly thats were your problem is. Your complaining about them.
