Any clue on Kosmik?

[G200driver]

Bare with me on this..I will get this damn file loaded...somehow

[dl7uae]

And...? Where is the .DAT?

This should be a text file, simply change the extention to .txt and attach it here.

Do you have a "kosmik.ini" or something like that for LogView? If not, I can make one.

Tom

[G200driver]

Let's try this again..

[dl7uae]

Okay, have I tried as Sherlock Holmes.

KOSMIK.zip:
Inflate and find kosmikCelsius.lov and kosmikFahrenheit.lov.

Open (yes, "open"!) a .lov to let LogView learn the device "kosmikCelsius" or/and "kosmikFahrenheit".

Import your device file (text file) *.DAT.

G200driver.zip contains G200driver.lov, OPEN it by LogView.

The motor rpm is 2-pole normalized.
Divide by half the pole number of your motor and your gear ratio to get the headspeed.

G200driver, what is the number of poles your motor has and the gear ratio of the heli?
I w'd make you a special device for LogView.

Here three .ini device description files for the KOSMIK.
One is for motor rpm of a 10-pole. Feel free to copy/edit for headspeed instead.
(I do not know what "encoder1", "encoder2" and "Tv" is. Both "encoder" values look like throttle on a -100/100 scale.)

Install Logview from here.

Copy an (or all) .ini file to %appdata%\ LogView\Geraete\OpenFormat (regardless of what Windows version you have)

Then, in LogView: Device --> choose device and port
(Port is not needed here.)

and i hope that Kontronik add VStabi governor mode

I don't think they will do that. And I agree.

GN everybody

Tom,

Thanks for all the help here..I'm working on getting this sorted out...My motor is a 10-pole motor and 9:7:1 gear ratio.. My headspeed is 2180-2300 depending on load conditions. I'll post here once I get a good file!

Think I got it...First flight on Kosmik...Thanks for your help Tom!!

I understand, but i still hope that you are not right because there is no way how any governor may compare with VStabi governor. I know that VStabi has not enought info as internal governor, but there must be a way how to do that safely. On a monday my Kosmik will arrive. If they will not add VStabi mode i will not be happy but i will not be angry, they know what are doing.

What is the default Kosmik BEC voltage?

[ZuvieleTeile]

Geez, Tom
You are really a night owl . . .
Good night!

[dl7uae]

G200driver, find attached YOUR device for a 10-pole and 1:9.7 gear ratio.

Swalko:

Someone says that someone believes it.
I do not believe in something, I'm thinking about it and measure/record the facts on the test site. No, Sir. The supposed advantage of "feed forward" cannot be practically carried into effect. Not with a governor for a brushless drive.
Less to no effect, but: Setup w/ feed forward tends to get critical for the user. MHO from the beginning. And, principally: Commutation and have the power to the PWM, belong together. Otherwise, it can quickly become dangerous. Again MHO.
Who wants to try it, okay, but then with an ESC with a weak governor. Here the Vbar governor can play its advantage. Relatively useless to risk an ESC w/ an excellent governor.

Tom

P.S. KOSMIK and device.ini for LV: Marcie from K gave me his file now. No difference to my guessed version. And still unclear what the two encoder value and "Tv" are.

[swalko]

Sorry, but you are not right. I dont need to measure because i simple used it. If i use powerfull motor i dont feel difference. VStabi governor is big advantage on low rpms if i use weaker motor (Pyro) and i fly in a big range of rpms (1200 up to 1900). I am not sure if this concept is dangerous or Helijive mode8 is not so safe as it should be. As you know i had accident, after that i prefer powerfull motor with internal governor more than Pyro and Helijive in mode8.

[desertstalker]

All that is needed from Kontronik for the Vbar to work is a mode similar to what YGE provide. A heli soft-start that then switches to a plane style control mode after initial spool up is completed (the speed of both are selectable by the user).

Should be no risk to the ESC or motor and the ESC is still managing the motor completely, just responding as fast as possible to changes in throttle signal inputs.

[jhheli]

Good we are not all the same...I still like the Kontronik gov better...but thats just me.

[helicraze]

I prefer kontronik gov as well

I use the Helijive governor on one heli, and the SK-720 governor on another (with a non-kontronik ESC) - Essentially they both do a great job.

The helijive governor is definitely better in being able to govern lower RPMs than the SK-720.

On my TDR, when it was setup with helijive ESC but using the SK-720 governor, the minimum governable head speed was around 1350 RPMs. When I switched to the Helijive Governor, it essentially starts governing well below 1000 RPMs. No comparison...

However, nothing beats the ease of setup of the SK-720 governor. You enter the head speed values required directly as RPMs, none of that throttle percentage guesswork there...

I have flown both on my Logo 600SE (Soon to try out the Kosmik on my XXtreme) back to back and, at least from my perspective, can't really tell a differance between the two.

I have had a VERY experianced pilot who I trust fly both (Back to back) and he can't really tell a differance between the two either.

I mean it makes logical sense when you think about it but I really wonder if the gains from the proactive govenor are so small that it's really beyond your ability to tell the differance. I mean If it's one one millionth of a second differance can you really tell??

Anyway I much prefer the Kontronik Soft Start and the clean installation the Kontronik allows me (Not so many dang wires running everywhere) Vs the V-Bar govenor soft start/installation. Plus there isn't SO many differant things to have to set up or get wrong (Or GO Wrong) when using the Kontronik govenor.

just my .02 though

[swalko]

I know VERY experienced pilot and he prefer VStabi governor . Everything is personal preference. I like VStabi governor with Pyro and on the other side i like my Xera 4530 with internal Kontronik governor more than with VStabi governor. Kontronik internal governor have really nice spool up. On my TDR with VStabi governor and Helijive in mode 8 i had not nice spool up. VStabi governor have tendency to overshoot.

And now back to topic:

1.) Reverse rotation direction can be set only with ProgDisc or performed by two phase cable switching.
2.) Default BEC voltage is 5,6V.
3.) Kosmic 200+ HV have stronger BEC than Kosmik 160+ HV (10A/30A vs. 7A/20A).
4.) Fuse is necessary (mentioned in manual).
5.) Supplied cables have 6qmm.
6.) You can shorten all supplied cables to any length you want (answer from Kontronik support).
7.) In applications where you get full Kosmik performance for a long period you need to double all cables (mentioned in manual).
8.) I found manual very explanatory. Some procedures and details are repeated so many times that you can not overlooked them.

[Groucho_]

Swalko, you'll be needing the longer ESC tray on the TDR from modelltechnik

[G200driver]

I know that mention fuse in manual, but no where that I can find does it mention not using it would void warranty. If you do us it, you'd better have a buffer pack, cause with that 4530, you will exceed 200 amps, pop that fuse, and be left in a bad sort of way as you lose power to everything. I'm glad I didn't install mine. If I had, I would have lost complete power and wrecked a lot of times as I would have popped it a punch. I

There are other people choosing not to run fuse as well. I set my voltage to 7.8 volts, and plugged a 250mah 2S 7.4v into spare receiver port for buffer. Just be sure a set your BEC voltage with pro disc before you connect 7.4v lipo.
