Building logo 600 All advise welcome

Yes, it is governor mode, no, you don't need a phase sensor. You will only need a phase sensor for external governors (VBar gov, Skookum gov, etc.). When using an internal governor (run from the ESC), no other equipment is needed. The Kontronik built-in governor is widely regarded as the best internal gov in the business. You'll be running a flat curve at whatever throttle percentage you choose (based on what RPM you decide on).

Thanks. I did a little reading up and concluded about the same.
So when i program the jive to mode 4 it automatically works governed? No need to fiddle with any other things? No gov gain or things like that? Man it always seemed much more complicated than that
Then whatever throttle percentage i choose, the resulting headspeed will be held consistantly by the jive? Does anyone have any idea how much percent throttle i have to run to get around 2000 headspeed with the 500kv motor and 13t pinion?

Also here are Mr Mel's Kontronik esc programming vids.

Super easy and the best ESC gov.

Wow thanks guys. Great advise as usual. You really allready helped out a lot

Tried watching mrmel's kontronic videos but they don't work. Says they're private..
They're not on his youtube channel too.

In short, Kontronik forced MrMel to remove the videos. Something I consider violation of the human rights and also bunch of EU freedom laws.

Yes some BS political correctness or something going on, Align winge about forum stuff, now Kontronic wants to alienate us, cannot see the point in taking down great ref videos, Kontronic, the alternative is...????

But I have programmed a few, quite simple with TX stick, VITAL- ensure that your throttle curve is 0% - 100% linear to program, otherwise the ESC will remember a limited stick range and you will get wierd results, but do:

Mode 1 reset,
Mode 4 Govenor,
Mode 9 Lipo protection (not vital but I do like the cell count pips)



I have the progdisc, if you can borrow one, I like to tweek: BEC 6v, Lipo protection slow down and 3v, spool up time left at 12s default. These not absolutely necessary at all.

Then I use the android head spead app, works perfect, use Mels HS calc to program the speads you want, then fine tune by altering your throttle curve live at 0% pitch, middle stick, then alter the rest of the positions.

VITAL: Use a fully charged battery to calibrate HS, otherwise the ESC will not give consistant results as the HS is a percentage based on voltage at boot-up.

When finished have throttle curves:

Normal 0% to 1st HS in 25% stick move then flat line with -3Deg pitch max, full +13Deg
Idle 1 Flatine at HS 2 Pitch +-13% symmetrical
Idle 2 Flatline at HS 3 Pitch as above.

Throttle hold at 0% throttle, full symmetrical pitch curve.
I also program in a throttle cut at 0% for extra safety, had a minor incident when canopy hit TH switch, never again!

Once you have experienced Kontronic govenor you wont want it any other way!!

[-kenny-]

I'm thinking of using a life pack instead of bec for extra security. I don't quit trust bec's fully

Great advise on the esc setup! So max collective pitch shouldn't be more than 13 degrees? Not that i was planning on running more

As far as esc setup, reset mode1, set mode4 and mode9 and figure out headspeed. That really is simple.

No problem, ref BEC, the only one I do trust, we are flying 2.5k TDR heli's on it, no problems at all, Jan Henseliet states in his manuals thate LiFe not necessary but up to you. For course HS use Mels calc and select Jive Mode 4 as govenor, doesnt get much simpler,

[-kenny-]

Do you mean the kontronic bec is the only one you trust? Maybe i have to reconsider then but i was thinking of using a seperate rx because i have an ar8000 laying around. What's the best way to supply power then?
I've been looking at mel's headspeed calc. It's real usefull. The only thing i don't get is peak efficiency.

[CyprusFlyer]

Correct, just make sure you have two cables Master/Slave from Kontronic to RX, use any spare servo port that way you spread the current draw.
Peak efficiency leave at 90%, have to find specs in the motor manual otherwise.
BTW I have the 560kv motor, 10 Cell battery, the 11T pinion is looking optimum, have one on order but 12 will do for now. Suspect there will be high current draw for lower HS, 1800-1950, not good for lower HS efficiently.

BTW if using seperate RX and VBAR, you will have to split the power between them, best to concentrate the power where the servos are so would prefer a third connection RX to Vbar, difficult with Mini Vbar as all connectors usually in use with separate RX. Satellites much neater, you then can use RX C as a second power input.

My kit came with a 13t pinion. But the motor is only 500kv. I guess they altered the kits a bit?

[CyprusFlyer]

Bought a bare bones and a motor seperate, actually was going to just upgrade the 500SE to monster power but soon realised I would need bigger canopy for battery size and a few odds and sods, what the hell, just get another heli.

I'm not trying to dissuade you to use a life pack but the only time I had a BEC failure on the JIVE was when I had a main pack failure. Your life pack would then at least allow the servos to work as a safety. I lucked out and my heli fell into the tall reeds and had no damage but with a life pack I would have been able to safely auto down with no power.

A 13T pinion is a great pinion for 10s packs with a 500kv motor. 85% should give you close to 2200rpm if that is the headspeed you are shooting for.

According to mr mel's headspeed calculator 67% should give me 2087 headspeed.. 73% should be 2200

I would use the Kontronik BEC and just use a buffer pack. The buffer pack is a small nicad pack running 5V and is there incase of a main pack failure or esc failure.

And it is nice for doing setup cause you can power up the radio gear with the buffer pack. You never have to charge the buffer pack, it gets charged in flight.

Correct for the non-atv adjusted percentage. I always adjust my ATV and use those percentages instead because if you are posting percentages online it levels the playing field. This was explained in Mr. Mels JIVE videos but I think they have been taken down.

Do you mean something like this? http://www.fast-lad.co.uk/store/2200...sf-p-4044.html
I just plug this into a free rx port and it get's charged while i fly?

How does this work exactly? Why should i adjust atv? That's travel adjust right?
Wow I feel like a noob all over again..
