Hi Vin,

Back in the old days of single channel, rate only gyros, the nose gear steering was a "go to" application. In your case, I would think about a relatively cheap single channel gyro (Futaba 401 or even cheaper), in rate mode on just the nose (with an adjustable gain channel but you could even do without that). That way you are decoupled from the 6 axis gee whiz gyro set up process, if you are using one.

In my experience you can crank the gain up very high, as the normal slop in the nose gear linkage kind of filters out any high frequency oscillation. Maybe with your guitar strings might need a bit lower gain. You can either adjust that with a spare channel or a screwdriver, just do some taxi tests.

As someone said, take care that you know exactly what is happening when airborne (retracted) but in these days of zillion channel radios you can probably just set it up to turn the gain off when retracted.

As Bob indicated these things can cure a lot of ugly steering problems.
