Need verdict from the Gyro Jury
I don't want to get a Ford vs Chevy argument here, Ford and Chevy both make great products. That being said, What is the differences ( if any ) of the Cortex and I-Gyro 3E and a brief " Why " would be helpful. I am interested it the user-friendly aspect as well as reliability quality if the product as well as the warm & fuzzy feel I hear so much about. Is one is better over the other, price not being one of these. I realize there are probably more guy's flylng Cortex at this time, but is the I-Gyro gaining popularity for the right reasons. Thanks for any and all input and opinions !!
Cheers,
Dan

Both work great.
Cortex is more flexible, its got 5 stabilized outputs, doesn't care whats plugged in, 4 ailerons and a rudder; 2 ailerons 2 rudders, and an elevator....doesn't care. It learns whats plugged in during the simple programming process. Can be modified by a cord thats included and the software is free.
Igyro implements hold mode better, you can fly in hold and it reverts to rate when you move the aileron or elevator stick (no hold in rudder axis by default), Cortex is in hold mode or in rate mode.
Not as flexible, there's 2 aileron, 2 elevator and a rudder output, no way to reassign without a lot of tinkering by mounting the gyro differently and fooling with the software. Works great out of the box but the programming cord is optional and extra, the software is free.
A long winded discussion is available in the May and June Fly RC Jet columns.

Same impressions here... tried both, they work well. The Cortex has the advantage that it can be set in any kind of plane without the use of a PC. My opinion is that heading hold mode in airplanes is plain ugly to see and fly,, I never use it.
Also there are two other gyros that I like more than this ones. The BL3GRC Iceman , the only one I know that has autogain (it also feels great, better than the germans). and the Eagletree guardian, as it is the only one with autolevel feature, wich is a safety bonus IMO. Both are considerable cheaper than the cortex and the igyro.

You can also have the same results with 3 good heli piezo gyros properly set up.. just wire together the gain channel wires, select the proper mode and servo match speed and you are good to go.

Flew both and decided iGyro all the way! Cortex has a more intrusive controlling feeling when the iGyro feels more natural and smoother.
Cheaper , just plug and play!
Ali and Sebart flying iGyro and report its the best so rest my case!

Would rather not use a gyro at all then the Igyro.... At least the one I used.
Loving the cortex. Had the eagle tree installed and it also worked great but the cortex is more precise and better for competition flying. Eagle tree is much better then nothing at all but cortex is better.

What was the issue with the igyro? I was going to buy one.

I must admit...lately i've been looking into gyros especially since my T-33 crash (I know gyro can't prevent a crash) but some jets have bad habits. My problem with gyros is my receiver have to go through this gyro to my servo..what happen if the gyro fail? I also have redundancy in all my jets (2 RX, 2 batt,2switches) but with a gyro that's useless. The recent crash at FJ someone was blaming a Gyro then nothing more about that. The other failure in Florida.. The guy was just about to take off and BAM!! no power from the gyro...I was waiting to hear what the problem was but nothing. That makes me nervous.
That's just me.

I follow what you said about the stabilization failure but what happens if the whole "box" fails or goes dead ; do the servo signals and power go thro to the servos ? Or is it game over ?

Probably have a better chance of getting in a car accident on the way to the flying field and getting your models destroyed. The benefits far out way the risk. BTW this is coming from someone that owns 1 turbine and flies ALLOT! I also cant afford to replace my one plane and I worry about many other things before worrying about the gyro failing.

You should be able to turn the gyro off in flight. I am running eagle tree guardians and they can be shut off in flight.It becomes just a pass thru at that point.

Some differences between the 2:
Cortex can have mixed channels (such as elevon) 'programmed' without a PC.
Cortex has 5 stabilised outputs that can be used on any channel.
Cortex will accept certain 'Bus' input signals (but will only output PWM)
Cortex can be used without a main receiver if using Spektrum/JR satellite receivers.
USB cable is included in the box with the Cortex.
Whether you need any of these features (either now or in the future) will depend on your requirements. The individual 'feel' of the gyro will pretty much be a personal choice as both will do a good job of stabilising the model.

I hear you Vin but if the gyro fails due to power loss inside the gyro then the link between the rx and the servo is lost..unless there are (NC) built-in relays on all the channels to hard wire the rx to the servos.
But don't mind me lol..that's just my phobia

I am with you on that..... as to the comment on receiver failing then I guess that would depend on the brand of radio system you are using.....some more than others.

I know man...my buddies at the field keep reminding me of my signature lol. But on a serious note..that's my only concern about gyro.
So anyone else interested in give gyros a try go for it
