and no, you can't simply substitute a Jeti receiver for them. I believe you can use a single PPM connection from a Jeti receiver to the Cortex and in the near future you will be able to use an S-Bus connection from a Jeti receiver to the Cortex. Still, you will always need a receiver of some sort and none of the various manufacturers are compatible with each other. |

I was re setting my model again and I was trying to understand this whole process this time and not just copy stuff without knowing what it is about (like I did the first time around) but I don't understand what this part exactly does, what would it happens if instead of 99% I would put 20% (for example) Thanks, Fernando |

If so, no you don't need to do it this way. You can use create a function switch any analog or switch and assign it to a channel then use that channel as gain. You can use endpoints or function curves or rates to set amount of gain. Using the wizard function and menu lets you combine a switch and analog for gain easily. A fixed switched amount plus a variable analog amount. But you can recreate this manually with multiple functions and mixes also. There's always more than one way with jeti. |

Great tutorial. But you should trim your plane with the Cortex off and then leave the trims as they are even when the Cortex is on. I am pretty sure that is the recommended action.

But trim is not memorized by the cortex. The centres are relearned every boot at power up. Your sticks should centered at boot and not touched until the surface bounce after boot. Minor trim changes can be made over the life of the installation without retraining as trimmed centres are relearned each boot. |

This thread is gold thank you! I just ordered a couple of Cortex Pros from Esprit.
One question I have is about DR / Expo and the zero gain mode. My goal is to practice new maneuvers with Cortex but also fly frequently with zero gain so I don't lose my skills to do 3D or XA in gusts. I am hearing one needs to turn the expo down when using gains. For example with my Extreme Flight planes I currently using expo of about 50% for landing type throws and about 75% expo for regular / aerobatics. This is just a function of the servo arms / servo end points etc set. Now with normal or hold mode if I need to use Expo of say 20% or 25% for normal and landing - is there a way I can revert back to my traditional throws and expos if gains are zero? Otherwise I will need to keep adjusting manually. For example - I am thinking - define logical switch based on gyro 3 position switch. Logical Switch is on if gains are zero. If logical switch is on - use a set of my current 3 rates and expo (landing, Aero, insane). If logical switch is off (normal or hold gains) - us gyro friendly set of rates and expos. Something like this?? Thanks. I am very new to Jeti system. |

My modes prioritized like this; Gyro Normal, negative gain, gain level depends on plane and if i add gyro feedback High Rates (no gyro, zero gain) Low Rates (no gyro, zero gain) You can add as many modes as suits your taste, with any combo of gyro fixed gain, gyro variable (knob), rates, and expo! Except if you have a DS-14 with too few modes. I don't use Hold. I have removed it from all my models last season. First it just doesn't feel right. A gimmick that i never used! Second, last season, i mistakenly bumped my gyro mode switch one flight from Normal to Hold! It didn't click that i had done it! Plane was acting really weird! Thought i had lost one or more surfaces. But after a really ugly landing i realize the mistaken mode! The HOLD is gone gone gone! And never to return! LOL Since 9/10 wouldn't take a strangers advice to just forget it exists! So my advice is try it! Try it high up! After you prove it to yourself, get rid of it, so you don't make my mistake. As for gyro on/off, my experience is a good gyro only helps you learn to fly new maneuvers faster, as it eliminates the noise in the system, you are not flying the noise, just the maneuver. Flying with it on, reduces the signal to noise ratio your brain is dealing with, and you "brain train" the moves faster. After your brain is wired, when you turn off the gyro, the burned in brain training (the fundamentals) are still there! You just have the added task of flying (correcting for) the superimposed noise. I have planes with and without gyros. Friends are always asking which gyro is in this one? In the cases where there is no gyro, I tell them i am flying "CORTEX Residue"! |

With my 3D planes it seems that I have a hard time judging stall speed with the gyro on. The same does not apply to my jets but that is because I tend to land with a bit too much speed most of the time so stall does not show as much. All could of course be caused by my limited skills. |

I never been a rate switcher like IMAC guys would do. I am 3D stick banger only! If you don't like full rate landings, then make a landing mode with Normal (gain) and reduced rates! The gyro can still push surfaces to full throw if its needed, but you cant! Just make sure you "train the gyro" during setup in full throw rates. Normal (Gyro, full rates) Landing (Gyro, reduced rates) High (off, full rates) Low (off, reduced rates) |
