Hard to go wrong with a smoothflite 16 or 26 depending on what you need done.

If you are using the Jeti RC system their Assist receivers are the obvius choise. Otherwise somtething from the Powerbox line of gyros will be a great choise.

Either a Cortex or Cortex Pro will be perfect. Easy to setup and use.
Talk to other pilots in your area and get their help before you buy anything.

Cortex and iGyro are both excellent in their own ways, Aura, Smoothflight

They all work, everyone has their favorite feel

I've fitted a Cortex in everything Ive built in the last 6 years. Always perfect.

A Jeti Assist needs a Jeti Transmitter to set it up, unlike the other systems that can be set from a laptop/ PC.

Jeti Assist also seems vulnerable to acoustic interference from the turbine, resulting in random surface glitching. It has been reported in the forums and I have experienced it on the only turbine/ Jeti Assist combination that I've tried. Reverting back to a Cortex Pro on the next one.

I appreciate everyone giving there preference of gyros, however could someone explain the pros and cons of different brands.I don't want to invest in one that is not user friendly or one that you need to be a electronic genius to set up.
thanks, Till Next Time !

More of it is feel versus features and that you're going to have to find out for yourself.

All of them are pretty easy to setup. The demon you plug in the servos and do a learning sequence that teaches the gyro what's connected where but the heading hold mode is really only good for 3D

The igyro has hard wired outputs so its not as flexible but the hold mode is better suited to normal flying.

I like the PB ISAT Gyro , only one wire and very easy to setup and weight nothing
here with a neat 3D printing support ...from RPM jet

Great gyro but you need to be running something that supports it like a Core radio or Pioneer powerbox, otherwise its the same thing as the iGyro3Extra without the channel slots

I run Jeti REX12A (Assist gyro) in my single receiver jets/EDFs and Cortex Pro in the larger ones. I prefer the Cortex Pro for ease of set up and use but I have never had any issues with the Assist gyro causing any problems. Get some help from local folks that can help you get started. Good luck.

I fly FUTABA and all my jets have cortex. I use the retracts as my sensitivity adjustment . I have found 30% gear up and 50% gear down works on all of them. With futaba you can set up a master to shut if off and a dial to move the sensitivity plus and minus. Dan

I think I am over my head with this gyro stuff LOL,30 % -50 % I am so confused.I am going to Heartland Jets this month and will be asking and check out stuff that I don't know about.

Jerry I normally go to Heartland Jets but Tim put it 3 weeks before Kentucky and that would be to much time on the road. You will be able to ask a lot of questions there. A cortex has a extra servo wire coming out of it that is plugged into a free receiver channel. This is use to adjust the gain on the gyro or turn it off. The 30 50 is the travel adjustment on that channel . Pm me if you want to talk. I will give you my phone # Dan

I personally switched everything over to the smoothflite because it has scale and sport modes, high, low, and variable gain, and AGC which automatically detects oscillation or flutter and dials down the gain. No more chasing gains.
Dual redundant receivers
high current and regulated power.
26 fully programmable channels,
3 axis gyro,
3 axis accelerometer,
compass and a barometer,
Gear and door Sequencers
full color touch screen interface (detachable)
Telemetry
AGC automatic gain control- no more wiggles or flutter.
VGC variable gain control from a switch or dial.
Dual power
Gyro steering,
Dual rudder brakes
Thrust vector control
Crow and spoileron control
Led indicator light
Failsafe switch
Pin flag
Scale, Sport, Aerobatic, and Proportional modes.
The Smooth Flite system allows you to assign as many Gyro outputs as necessary including steering, dual rudder braking and thrust vectoring. Also you can actually reach out and talk to the designers correctly which is a huge plus for me.
BUT, all that being said, any decent brand name gyro should work well for you.

The guy said he flies futaba and a basic model rx most likely a non serial bus type So he is limited to PWM type gyros

cortex and cortex Pro
i gyro

Jerry dont let any of this confuse you

Buddy up with someone at your field or locally and stick with what he is using for now. ten different people have ten different opinions.

There is a Cortex Gyro and a Cortex Pro gyro, that I prefer these days.

The Cortex is easy to program and doesn't require an external device.

The instructions come in the box. It will have you move the sticks in each direction, then flip whatever 3 position switch you want to use to enable the gyro.

After you do the setup and remove the bind plug from the cortex, and turn the power off and back on again, the middle switch position will be off and the light on the Cortex will be RED.

The other 2 positions will be either a GREEN Light and the other will be a YELLOW light.

The Green is heading hold like you would use for hovering and specific maneuvers, and the Yellow will be a normal gyro operation for regular flight.

You will have to figure out which way is which in your radio by checking your travel adjustment settings, but Middle is always OFF.

The end point you use on either end will be the percentage of correction the gyro is set to. So 30% travel adjustment would be 30% gryo correction.

So if you switch one way and Green light comes on, you will be adjusting your percentage of heading hold. So travel set to 30% would be 30% gryo correction.

And you switch the other way it goes to Yellow light, and you set it to 40% travel amount in the radio, the gryo will be set to 40% gryo correction.

These percentages aren't necessarily what works for your plane, but just examples.

I have one plane that is set 40% regular and 50% heading, and another that is 30% and 30%. It just depends on your likes, radio, and plane.

I know that is a bit wonky but I help it helps. There are quite a few videos on them.

If you can get one, either Cortex or Cortex pro depending you model, hands down the one of the best out there. Setup is a breeze!
