Testing a new Kontronik Jive 80+HV ESC

[OICU812]

Well I got a HV80+HV, to test one out. I got in a few quick flights today at around 85-88 degrees F ambient temperature. This is on one of my NEU 1912(H)-1Y equipped helis. I chose this heli specifically as I have another one identical only it has a CC85HV esc with newest and tweaked software. I was basically trying to get the HS I wanted and did not get a Elog done as well, I am waiting for a new Eagle Tree as my last failed. However first impressions are very good indeed, the governor from the few flights I got on it is awesome, even better then my 55s ever were, and miles ahead of the newest CC software as well. Where the Kontroniks always shine is on the governor of course. In some quick hurricanes on the CC you can still get a surging effect on the tail, it is managable but annoying, the Jive however is rock solid. My 55-10-32 would have certainly shutdown on over amp or thermal guranteed with what I threw at it, and I do not have a heatsink on the Jive yet either. More to come for sure, for now here are pics of the Jive and also a picture to compare it to the 55-10-32. I purchased the Jive from Ken from www.rcflightstore.com (http://www.rcflightstore.com)

What is your cell count and pinion used on that heli?

Sorry it is a Logo 6003D

10S, Flightpower Evolite 10S1P 5350mah packs
NEU 1912(H)-1Y with 13tooth Mod.7 HB Pinion
HS goverened at 72% which is skytached at around 2350rpm.

That's some good info Shawn... Thanks! :thumbup:

[th3tick]

Excellent! My 1912 has a chance to return to my L600 now!

One other question: are you going to give their BEC a workout? They're rated the same as the HBEC, so it would be nice to be able to eliminate that weight and wiring...

[OICU812]

Well John, don't strap it on yet....

I did a couple flights today, with not as good results, in the end I am thinking the Kontroniks are just not going to work with the NEU?? At this point I just don't know. I do however have it recorded on an Eagle Tree I borrowed. Long story short I was banging it hard on purpose, abit after 2 minutes into the flight the Headspeed completely dropped, it didn't slow down I mean zero warning, so a bad auto in. Upon looking at esc it was flashing (8) times. I do not know "yet" what that stands for. I will look for this when I get home as well I will upload the graph and see what kind of amps it was pulling through. I can tell you it puts out more than the CC was, however the tail today with no wind was not keeping up on punch outs and as said it cutout. I put it up again knowing this could happen again and it did. The esc was only 40-45 degrees C, so I suspect this could not have been a thermal imho....So... back to the CC85HV for this motor I guess :(.

[OICU812]

john, your pm box is full btw...;)

And no I am not using the internal BEC as I use 2S lipo direct. :D

[fireup]

Ok, just made an order... I don't know if I should be thanking you for making me drop $400 on this thing.:bomb:

[OICU812]

Well Kevin I guess this depends on what motor and heli you are putting it on?

I think the NEU on this heli is just to much, check out this graph from when it quit, it took over 129 amps to shut it down. Also note the power throughput, over 4200 watts, crazy power....BTW 8 flashes means the following I found out.

"Over current detected by hardware, immediate shut off, no restart possible".

Well it did just that, immediate allright, thank goodness I had some wind, thats all I know, lol.

[fireup]

"Over current detected by hardware, immediate shut off, no restart possible".

Can you elaborate? I would like to turn this feature off.:)

Well Kevin I guess this depends on what motor and heli you are putting it on?
I'll be using with Scorpion 4035-500 with 12s on a custom 90 size electric.

[MrMel]

I say change the motor, unless you have 17 degree pitch or so your burning watts/pulling amps off for nothing.

[MrMel]

Can you elaberate? I would like to turn this feature off.

Kontronik was quite clear on this, feature is there to keep the magic smoke inside the unit :)

[OICU812]

Yea like Fredrik said there is no way around this setting, it is locked in 100% for certain.

[fireup]

Ok, so what's the maxium wattage can this thing pull before it shuts off? 4200 watts?

Can a heatsink be added? looks like the case is potted.

[OICU812]

Yes you can adhese a heatsink easily, there is an actual heatplate there on the esc. Understand this shutdown from amps, not watt throughput and not from heat. In fact when I landed the esc was only 35 degrees C on that plate, not warm at all. If anything I think Kontronik may have made the protection limit to low. If I am to guess I think their over amperage setting is somewhere between 120-129 amps where mine peaked and shutdown.

[MrMel]

Ive asked kontronik the same question too, I gonna post if I get an answer...

[OICU812]

The fact they made it a complete shutdown instead of a slowdown really pisses me off actually. I as well sent Motormike my comments, hopefully they can do a revision or firmware upgrade of sorts to change that for future ones....

[OICU812]

For now those who want to run the 1912(H)-1Y on Logo 6003D with 13tooth, here are the parameters I found to work best with the CC85HV.

[OICU812]

Oh also Kevin,,,, don't forget if you are running 12S you will be pulling "MUCH" less amps from an esc versus 10S of course. Just be carefull on your first tests to make sure you're ready for an auto "in case" till you get a grip on the amp draw etc and log it....

[fireup]

I don't think it will be "Much" less, it's going be a 90 size bird (690mm blades) and not a 600 size. We'll see, hopefully it don't shutdown when I'm inverted. I've only successfully recovered from an inverted failure once and it was luck. I don't think I can repeat that maneuver again.:)

[OICU812]

Well you will not need as much pitch of course running larger blades and likely a slower headspeed. Recently I logged a 600mm machine with Actro 32-3 on 10S with 19 tooth running 2275 rpm with max amps at 92, then a 690mm machine on 12S with Actro 32-3 on 15 tooth and around 2025rpm and anyways,, amps on it were only 95 max.

Depending all on what you want I guess. Just do some climbouts fast and hard and pointing to wind, if no failures and your logger shows you have room then you can goto the inverted buisness, lol. Good luck man, if its not opened you can always return it right???

[viperhawk]

How are the Jives working out for you guys these days? Mine should be on my doorstep today.

[OICU812]

My newest ones are working perfectly fine, finally 99% happy. Still wish they'd remove the current shutdown all together, but seems they are to stubborn to do so at this point.

Hi Shawn - how does the latest (V5) 80HV work with the Neu 1912/1Y? - can it now survive the original testing you did in July that caused the shutdowns?
