E5 and Ikon settings for tail "D" settings?

[Dw87]

I'm setting up the d value on the tail. I'm running 2050 h.s. and high speed gears. Right now I came up with 29 for the gain and have moved on to stopping the tail bounce when I release the t/r stick. Default was 40 and I have varied the d value between 25 to 55. I will keep experimenting but I was wondering what values others had.

Thanks

Never had to up D gain on the tail on my Synergy helis.

What is your tail rotation rate at?

[Dw87]

I was using that ikon setup chart / PDF. I set the rotation rate at 360 as instructed.

I got the gain set from fast backwards flight then took that number and multiplied by .66.

The did the up down climbs and descents and the tail stayed pretty good without ant tail precomp. So I'm on the pirouettes. When I release the rudder stick the tail over shoots then drops back. That's what I'm tring to set, tryng to get crisp stops.

Chris, do you by chance happen to have an e5 / ikon setup file I could look at or have ?

Thanks

[Chris Sexton]

Yeah that sounds odd..

I do have an e5 file. I'll add one to this thread tomorrow. I left my laptop at work.

Thanks, I look forward to compairing files.

Just curious, what part sounds "odd"?

Depending on blade, you might have to play with D gain on the tail. I'm in the boat with Chris that I've only ever needed minimal adjustment there.

One thing though, you say release the stick. Are you letting go of the stick entirely while pirouetting? If so, modern electronics are fast enough that they will try to follow the oscillation of the stick as it bounces back to center. You'll get fast wiggle/bounce in the tail from this.

If you want to really check stops you'll need to drive the stick to center as fast as your thumb/finger will allow. You're looking for a quick stop, but not an overcorrection with a "bark" noise from a sudden pitch input.

.

The d gain is what I'm adjusting. This is both full piros as well as just push right and left commands.

I've tried both letting go of the stick as well as pulling the stick back to center to minimize any stick bounce back. I'm 100% sure it's somthing in the setting so and not the stick bouncing. I run the tight springs on my jeti tx as well as a tight spring tension.

Thanks all, I do appreciate the inputs and help.

So I made a little bit of progress this weekend with the settings. It was suggested to me to do a master reset on the ikon and start over. Any idea how to reset the ikon?

[stevolution]

Its in the the software. I believe its "file" tab and reset to factory default

Bingo

[Dw87]

Chris, did you get a chance to see if you could find a e5 / ikon setup file by chance?

Also, is there a way to check what firmware vs is loaded?

Thanks all

[Chris Sexton]

Crap totally forgot about the file, sorry I will make a point to check tonight.

As for Firmware, when the iKON is connected to the software, the firmware version is in the menu header near the "X" to close.

[Dw87]

I really appreciate it, thanks.

I was flying this weekend with a guy that has 3 ikons and between us we couldn't get the d setting to make much of a change. His thought was that master reset and or its a defective unit. I'm not quiet sure I'm ready to got that far yet, so your file would really help as well as be appreciated.

I'm surprised that there isn't an ikon file resource location someplace for different setups.

Thanks again all

Here are my current E5s, e7se, and N5cTT files. I dont have a current E5 on 556 to go pull the file on. I can tell you the settings aren't far off.

[Dw87]

Thank you sir. I'm running a stretched e5 with 606 blades on 12s.

Thanks again

[Dw87]

Thanks again for your files Chris. However it didn't do anything noticeably different. With the d turned down though, say to 10, I do notice that the tail locks ok with nose left, but nose right it still bounces. The heli does piro about the same rate in both directions.

Thought to thing to try?

[kayakboy69]

Make sure you adjusting the bank u testing it will mess you up .. ask me how I know !

[Chris Sexton]

When in doubt, start over. Playing with gains makes it very easy for things to go arye. Reset the gains and start over.

Also I have seen behavior like this caused from binding in the mechanical setup. Pop the tail control rod off the servo horn and see how smooth and free the tail system works. IF you can't get the tail slider to move under it's own weight, you have excess drag on the system.

[Dw87]

Thanks guys.
I did check the t/r linkage, smooth as silk. I have the fbl tail belcrank on the heli as well. I also checked from the servo back to make sure the pushrod isn't binding any as well.

After Chris posted the files, I tried a full reset of the software. I reset up the servo's and such then I copied in Chris's setup 2 & 3. I guess I'll try a full re setup as well just in case. I'm starting to think there must be something up with this unit. If another try at a setup fails, I'll have to find someone to send it to have them look at it. I'm not sure what else to try other then just mess'n with it.

Thanks again all. Sorry to bother you all.

It seems that if I "up" the p gain from the 29 I had to 45 the bounce back is very minimal. Way better then before. However that was just hovering in the yard. I will have to see how that gain is flying around though.
