Lots of different gyros out there, which ones are you using? Do you really need the best one out there? Not that im trying to skimp on parts for my a/c, its just that I dont see a need for some of the more expensive gyros out there. Thanks for the input....






wouldnt it be cool if they made a gadget for our planes......

maybe I should be a little more specific, gyros for yaw....

Have you tried a search? I remeber gyro discussions in the past here.

Hobbieco has two gyros, one for about 70.00, single output gain is tweaked via pot on the unit. It works great and has good gain adjustment. The second one costs about 120.00 has two outputs and can be controlled via radio for gain settings. Both can be used on any Axis. I am using one in my BVM MIG and one in my Bob Cat both work fine.

I have an Expert gyro on the nose of my Kangaroo. It seems to work very well. I think they only make one but it is the airplane model. Can be turned on/off remotely from the transmitter.

I have helped several people now who had Expert gyro's on their models. IMO they would not go to a high enough sensitivity compared to the 400 and 450 gyro's I've been using. Also, I have seen large neutral shifts when changing the gain. Just stating what I have seen.

My Expert gyro is only connected to the front wheel on the Kangaroo and I just turned it up to about 75% and have never adjusted it. Maybe that is why I have never noticed any neutral shift when adjusting gain if mine has that problem. I will check and see if is shifts from neutral position when I adjust it.

The Hobbieco gyros do take about 2 - 3 seconds to boot up!! That is when I turn on the radio, the surfaces that are being serviced by the gyro's don't come to life for up to 3 seconds, after that boot up all is normal. I have had the gyros out in 90+ temps and in the cool basement @ 62 and have seen no drifting of center trims, or any effect by those ranges of temps. The less expensive single output gyro seems to have more gain sensitivity that it's dual output brother. Gain sensitivity on both versions is fine for nose wheel and rudders, the $70 dollar one just seems to translate to a more active, deeper through when the gain is dialed up near the Max.
