What Gyros are you using for your jets.
The JR 370 gyro seems to be the gyro of choice for the jet community. With good reason, they are compact, reliable and work well. And also a little pricey, IMHO. Im interested to know other gyro options that might be less costly but have similar results.

A question for the guys that use the Bavarian Demon Cortex gyro in their jets. I have a BD Cortex, which I have used in a smaller electric aerobatics plane, just to see how well it works before installing it in a jet. It works great, and makes the plane feel as if there is no wind at all, but assuming 2 Ailerons, 2 Elevators and a Rudder, what do you do to stabilize steering? Do you use a Y harness with the rudder channel? Install a separate gyro for the steering?

I was considering the demon but it has some limits when it comes to multiple surfaces applications

I have installed five (5) iGyros with GPS in my planes. Three (3) of them are original iGyros and two (2) of them are the ones that come with the Powerbox Royal SRS.
Very happy with them and the support of Richard in their forum in case you have a question, is great. Based on this experience, I wouldn't install anything different in my planes.
Several other pilots in our club have also installed iGyros (at least five more).

I am loving the eagle tree Guardian. Its $75 and with the new software you can switch heading hold on and off. So for $75 how can you afford not to install one? The benifets are huge. Now when I am flying scale on windy days my plane does not flop around in the wind.
Would love to try the cortex someday.

Twin F-15 and 46% Ultimate
I use Sbus/Robbie systems and you are limited on outputs unless you use Y harness. My F-15 is 2 rudders, 2 elevators, two ailerons and nose wheel. Before it gets confused, I never said there was a problem just some limitations you can still use it on anything just is limited for me because of the way I setup my stuff.
setup is a breeze on the demon for sure but I like the GPS feature on the Igyro because it can adjust gains as needed for the particular speed your at.

From the Powerbox website:
- Extremely accurate triple-axis MEMS sensor
- Special regulatory algorithm designed for fixed-wing model aircraft
- Menu-based setup assistant
- Three-stage flight phase switching
- Three axes distributed to five servos, each adjustable independently
- GPS-regulated gyro gain
- Integral delta mixer
- Can be installed in any attitude
- Graphic OLED screen with 128 x 64 pixels
- Ultra-simple menu-controlled programming method using the SensorSwitch
- SRS technology for use with various bus systems:
Futaba S-Bus, Spektrum DSM2 / DSMX, JR DMSS, HoTT, M-Link and Jeti
It looks like the two have exactly the same number of I/O's

Im not talking about physical connections, since you seem to be trying to make something of my comments please go back and read further on the powerbox systems page on the product description. It talks about not being limited to just those 5 servos when you use things like Bus type systems, which is what I stated in my post. Here it is from the website.
"The need for mixers, such as elevator to rudder or flaps, is eliminated entirely. The iGyro exploits the latest servo bus technology to minimize the extremely complex wiring arrangements necessitated by previous gyro systems."
Here it also talks about the GPS sensor and the auto gain adjustment based on speed.
"The ability to assign any channel to the gain adjusters makes it possible to set up the desired gyro effect accurately in just one short flight. Independent adjustment of each of the five outputs is possible, enabling the modeller to set up gyro gain and direction of effect precisely. The separate GPS sensor provides a means of obtaining a constant gyro effect over the model’s full speed range, effectively eliminating the problem of over-compensation leading to oscillation in high-speed flight. In version 16 and later the software include a menu-based setup assistant which makes it possible to complete all the settings in just a few minutes."
Forgive me if I am wrong but I cannot do this with the Demon and thats why I consider it to have some limitations verses the Igyro. I was just giving my opinion and if I am wrong sorry about that I have only read it instruction manual and read peoples comments from this forum and Flying Giants.

Not trying to make anything of your comments, simply trying to understand your post.
This statement you made is confusing to me.
"I use Sbus/Robbie systems and you are limited on outputs unless you use Y harness."
So what I think you are saying is, by using a serial bus radio setup such as Futaba there are no limitations as to how many servos can be used on each output of the gyro through the use of S-Bus Servos and wiring.
If so, that would be a nice feature for some models.
But I would say for the great majority the Cortex would fit the bill perfectly.

No worries, I am a futaba user and I use Sbus so it allows me to link in multiple servos without using the extra wiring you would need without Sbus, this would require servo matching with either a programmer or matchbox and some Y harnesses. I wasn't trying to saying it wouldnt fit his needs just trying to help him gather info on what gyros people use.

Gyros have been the cause of an explosion for Flybarless helis . Gyros for fixed wing flying are gaining in popularity, and not just turbine powered models.
In the last year gyros in jets has been on the rise. They make any model that much nicer to fly. Bad weather conditions are not as much a limiting factor either.
Try one in your model I'm pretty sure you will like it.

Yes, Serial Bus Systems have some nice advantages to them. While the Cortex can be setup with a S-Bus input it is still a pwm output.
