It depends on the model you have and the size.

Please give us more information.

For an airplane rudder, the best one is one that can be used without heading hold. From the current gyros listed at the JR Radios website: [link]http://www.jrradios.com/Search/Default.aspx?CatId=RPG[/link] It seems like all off them are heading hold. If you can find an older gyro without heading hold, or you can use the newer ones, but make sure you disable heading hold right after the gyro finishes initializing. You do not want to start a take-off roll with the gyro on heading hold. It will be your most interesting take-off ever.

Size, model and other paramaters have very little to do with gyro selection, as gyros nowadays are getting smaller and smaller.

Not sure what the issue is but I always take off with HH set. I use a 3 position TX switch OFF/HH/RM. I set HH up in the middle position so in panic mode all I have to do is move the switch in either direction to get full rudder control.

Typical takeoff routine is - power up the TX (switch in off mode), Power up the planes electronics & let the gyro initialize. Taxi out to takeoff position then switch the gyro to HH mode, power up and takeoff. As the plane breaks ground switch back to OFF mode for normal rudder use. I typically don't use rate mode.

Have 6 tail draggers running rudder gyros.

Some very good rudder gyro threads

It seems to me that when I first responded the word "gyro" above was the word "servo".

No, I'm still looking for a good dependable gyro to use with a JR DS 8231 digital servo, which I already have in place. The plane is a 100" span Texan AT-6, that weighs 28 lbs., and ground loops during roll out after touchdown. Take offs are arrow straight, but rollouts after landing groundloop, and drag a wing tip.

Thanks for your help.
