Ok, I'm done reading that thread, I can only say, WOW! my head still hurts but I now understand assist a bit more, I also got an answer to my last question on that thread, I've seen the note bellow the Dampening only, had no clue what it mented, I now understand why they put that note there.

Allows trims and Batterfly.

Thanks Mark, I will check those out for sure.
I also found a heli site, Helifreak I think that also has some good general info on the Jeti radios, haven't had a chance to read them yet.

After all the reading that I've been doing, I'm almost there with assist, the thing is, it will be a first time for me using gyros in an airplane and I have to learn all this stuff about gyros by sawlowing a pill also Jeti, as many have pointed out, gives you the ability to program a funtion in a few different ways ( choose the one that you like the best ) well, in my case ( I assume this is true for newcomers) I don't know yet which way to program what I want since I'm not completely familiar with all the ways how to, I've been trying to catch up with the basic knowlage how to do a basic airplane programing and I'm there now but, without having the time to put this knowlage to practice is all up in the air ( punt intended )

I will finally be having some time off this week to possible do my first fligh with my Jeti radio, I'm also planing to set up the assist part of it to start the learning process with it, ( experimenting with it ) so then, my 30cc PC21 which I really like is going to be my test bed for the assist.

I will be posting a report on the flights Fri night.

If in doubt you can certainly leave the Assist in it's default state of Assist Off and just use it as a regular receiver to get your rates and expo at least fairly close and the airplane properly trimmed and flying well again. Then you should be able to simply do the final Assist configuration and enable it and at least be confident that everything else is good to start with. Assuming you use Normal Damping with the Damping Mode only control set, turning the Assist on WILL make the airplane slightly dead feeling compared to the Assist being off. What I normally do is set all assist flight modes to Normal Damping / damping only, make my rates/expo flight mode specific and configure and AssisOff control I then use that switch in the switch field in the dual rates menu. Since I have both flight mode specific and a switch set for rates, I use the flight mode to set the basic rates for AssistOff when the AssistOff switch is active (Assist is off) and then I increase the rates by 5 or 10% and decrease the expo slightly when the Assist Off switch is other position (assist if active).

Works quite well and the airplane "feels" pretty the same either way, just more locked in..

I can help you with Assist Friday, it’s pretty simple once you set it up the first time. As Wayne said, you can always turn it off if something starts going wonky. Pretty sure I can help you get it setup the way you want, or recommend the way I would do it and you can decide what you want to do. I’ll bring the ice chest lol....

I'm planing to set up my airplane about the same way you are recommending, assist on/off specific switch for sure, use the flap switch for the assist fl mods, a knob for all 3 assist gains, definitely I will get the airplane in the air to trim it and to get it flying normal again, after that on the ground we will turn on the assist portion, check the plane to make sure the assist is responding correctly ( right wing up, right aileron up and so on for the other control surfaces ) I also know ( from reading your postings ) about when turning the airplane on, it should be in the normal fl mode and to wait for the assit to be arm then it's ready to go flying, I will be using normal dampening in all 3 fl modes and dampening control set on, the last part you talk about rate and modes and switch, all that is new to me, I'll have think about it to see how it works, I'm sure I will adopt that in my programming, this is the first time you mention it, but I remember reading about the expo been a bit too much when the assist is on and the need to reduce them.

Thank you for taking the time to help me be successful in my Jeti/assist venture.

I'm still at work but I now have the time to read about what you are saying about the rates and expo when using assist, I understand what your saying about the airplane feeling unresponsive, that makes me think of Harry's little biplane experience using the assist gyro for the first time some 3 years ago, he said that he had the handling of his little biplane dialed in but when he used the assist gyro for the first time in his biplane it was very hard to fly because the controls were unresponsive, thanks to you guys and I'm sure others Jeti improved the assist gyro to what it is now.

You are saying, you are using the gyro master on/off switch also as the high/low rates switch ( expo comes with H&L rates ) when the switch is in the OFF possition ( assist off ) low rates are active to make the airplane fly soft ( the way I like it ) and when the on/off switch is in the ON possition ( assist is on ) the high rates are active to have about the same control ( feeling ) of the airplane because assist is making it less stick responsive ( my inputs)

Just remember that after you get the trims adjusted with the Assist disabled you should land and repeat the stick calibration procedure so the Assist knows where the true centers are. With damping ony set you probably won't notice it much but with trim in there since the stick priorities decrease the gain with stick deflection by having trim you will be effectively reducing gain on that access at all times.

Copy that on the sticks recalibration after the trim flight, I'm planing on a check list so I don't for get to do all these steps, I already have them written down on my notes, just got to organize the check list.

CARS II

My Feedback: (7)

Flying on dampening mode on all 3 modes, what about if I make a trim change when flying with the assist on? Do I have to recalibrate the sticks on the ground again?

Thanks.

No, it was bad because it was too responsive. Jeti was badly advised and they made the Assist into a flight controller, not a traditional gyro. It took over the controls and moved the surfaces far more than the stick commands. I swore I would never buy another Assist. But enough people told Jeti that they had ballsed it up and eventually they put out v1.12 which corrected many faults such as the default stick priority of 60% but most importantly included the "damping only" option. With v1.12 the Assist is a decent gyro and I have bought some more.
I disagree with Wayne increasing the rates when the gyro is switched on. If stick priority is 100% or more then the Assist has no effect on full travel rates. All gyros, not just Assist, have an effect similar to expo so I would reduce expo with any gyro switched on, but no change to rates.

Ok, so I will have low rates with the usual expo % that I use when the gyro is off and high rates ( which is the recommended max control travel ) when the gyro is on with a reduced expo % from my usual %.

Hope that makes sense.

Also lately, I've been flying all of my airplanes including jets with the elevator rate set on high and 35% expo, rudders on high with 45% expo and I feel comfortable flying the airplanes at all speeds, I've been working to do the same on the ailerons, this way I dont have to be switching from low rates to high rates any more, I know other guys fly this way.

Hello.



It seems to me that you only can choose one switch to switch both dual rates and exponentials on and of at the same time. I would like to have one switch for the dual rate function and another swittch for the exponential function. Is that possible in the Jeti system?

My first thought is, maybe it is possible using two funtions where rates is used on one and expo on the other, but both affecting say, the ailerons, how about using a proportional control like a knob or slider to increase or decrease the % of the expo?

I suppose I will find out tomorrow for me.

I personally don't see anything the slightest bit wrong with the way the Assist flies without damping only set as long as the aircraft you are flying doesn't require flight modes that involve trim changes. In fact, for 3D aerobatics aircraft with which you want to perform extreme maneuvers I find it the preferred setup. While it's true that going from V1 of Assist firmware to the next release was quite a shock when using the previous Assist setup, starting from no Assist was not a problem at all and I personally find that without damping only set the airplane files almost identical whether Assist is on or off. The only difference is that with the Assist on
the airplane feels very locked in.

As for not increasing the rate, in my experience it's absolutely necessary unless you always fly at high rates and in fact i don't increase the rate for high rates, I simply decrease the expo. While I understand that 100% stick priory disables the Assist completely at full stick deflection, the Assist only sees full stick deflection for 100% rates if that is what was selected when performing stick calibration. If you calibrate using a low rate of say 50% the stick priory will disable the gyro at full stick in that rate and at 50% stick deflection at 100% rate. So if you use 100% rate (you really should) to calibrate the sticks and also use lower rates, then the Assist will never fully be disabled at full stick deflection for the lower rates and you WILL need to increase the rate to maintain a similar roll rate at full stick, etc.

How did you know I was looking for a set of them metal bottoms for my DS12? can you guys include Blue color ones, I like to match them to my stick ends, the color blue is very popular

I'm just starting to play with an Assist prior to installing in my next project and looking for some clarification on the Damping Only (allows trims and butterfly) menu item.

Coming from Cortex/ Cortex Pro, I understand the Normal (Damping) Flight Mode and the effect trim has on Stick Priority and gain fade out.

I interpret the Damping Only option to not include Stick Priority gain fade when you have to trim away from the learned neutral point, however, assuming that trim and stick position are treated the same by the gyro (it can't tell one from the other), I could not detect any difference in apparent servo response to moving the Assist between having the Damping Only box checked or not and with a trim offset selected. It would still fade out the gain as the stick/ trim was moved

Can someone provide an explanation of what the Damping Only option is actually doing in Normal (Damping) Flight Mode?

Thanks

How about setting rate/expo to flight mode specific and then having a switch assigned as well and for each flight mode, set multiple expos selected with the switch.


Something like this
FM1 Aileron = 50% rate / 20% expo when switch is in position 1
FM1 Aileron = 50% rate / 30% expo when switch is in position 2
FM1 Aileron = 50% rate / 40% expo when switch is in position 3
FM2 Aileron = 75% rate / 20% expo when switch is in position 1
FM2 Aileron = 75% rate / 30% expo when switch is in position 2
FM2 Aileron = 75% rate / 40% expo when switch is in position 3
etc, etc.

Jannica

Yes, I think thatīs the way to do it.
