Example of problem:

Doing a rainbow from left to right starting from a hover, full collective up and over the rainbow and when I back out of the collective at the end of the rainbow, the motor seems to quit for a second or so. Anytime I back out of the collective doing anything, there is a pause of a second or so.

From a hover to full climb out, awesome power until I back out of the collective then I get the pause.

Equipment: Furion 6, 12t pinion, 2200 head speed, running Voltz 5S 45C 4500 packs (X2), 12 degrees of pitch.

Things I have tried:

Re-programmed the Jive, Mode 1, to Mode 4. I also tried Mode 1, to Mode 11. No change in performance in either mode and I get a solid red light when I land on the Jive.

Re-soldered all bullet connectors on both the Jive and the motor, no change.

Replaced Main shaft thinking it was slipping on the one way, no change.

Completely at a loss right now. Any suggestions are most appreciated.

Thanks!

What type of lube are you using on the one-way bearing? If it's grease, clean it out with a good(brake)cleaner and lube it with ATF or Tri-Flow.

Mine Jive did that a several times where I would momentarily lose headspeed. Took me awhile to figure out the problem. Then the Jive started to shut off completely and I had to auto, usually at the end of a rainbow or tic-toc. Finally it wouldn't not start anymore and I got lots of error codes. I had to send it to Germany and get a new one.

If you look around on the forums you'll find it is common with some Jives. I don't know if they made a bad batch of them, or what is the problem.

My advice to you? Send it in before you need to buy a new aircraft. Autos with low headspeed can be expensive, and the Jive cuts off because it is sensing too high a current (i.e. you're pulling too much collective).

Definitely sounds like a one-way bearing issue instead of the ESC. A buddy recently had this same problem using a CC ESC. He switched to the Kontronics HV 80 only to find the problem was his one-way.

I may be wrong here but, wouldn't the one way be slipping on hard collective punch outs? Everything works fine until I get out of the collective.

Sam, you are correct. I suspect it is the ESC, I imagine that there is an overcurrent protection feature for that ESC and you're hitting it. (although it may not be user adjustable, as some other brands are) If it were the one way bearing slipping, it is probable that others would be having the same issue, and that is just not the case.

New kit, box stock! Didn't add anything. I will try cleaning and re-lubing though.

Is this a new Jive Sam or were you using it before?

If you've got the ProgII card, you can try selecting the "smooth +" setting to decrease the holding power of the governor.

Yes, but for a Scorpion and Jive there is no playing with the programming needed at all. If he has to play with the smoothing gain then the something is wrong with the ESC. I fly Kontronik and have for a long time. Some motors need it tweaked a little, but a Scorpion/Jive work perfect out of the box and if not then one of the two is defective.

^^^ I think Kontronik either put out a bad batch of Jives or else it is something with the V9 software, but my Jive did the exact same thing. If you look through the forums, you can read several threads of Jives mysteriously shutting down.

I would call and send it back. If it is brand new maybe you got a bad one. Hard to belive but possible. I wouldn't risk crashing your new heli because of it. You don't have another esc around you can swap it out with just to try it, or maybe even a buddy has one. That way you can at least identify or eliminate it as a problem.

I get a hiccough on my Jives on different helis when unloading the disc, my feeling is that it's somehow related to the governor, bit disconcerting but no harm come from it!

Well I finally figured it out.

I decided to use Power Pole connectors (first time) to wire my packs etc. The Jive 80HV has very short leads so it required an extension to reach my packs. This is where the problem was. The Power Pole connectors are installed using a crimping tool that is squeezed by hand. If you squeeze too hard, you will deform the end. Well, I did not squeeze quite enough and the wire slid out in my hand last night when I was disconnecting my packs. I had an intermittent problem going on the entire time.

I had replaced all my bullet connectors on the motor and ESC but never thought about the extension.

I installed a new power pole and just test flew it. Problem gone and got a nice bonus of about 20% jump in power! This heli is absolutely awesome!

Thank you RR and all the guys that helped me track this one down. Once again, chalk it up to good ole’ user error!
