3DMP XL-E, 12T, Jive 80HV & Pyro 30-12, 12S, NHP710

The stock kit gearing gets the following throttle settings/ headspeeds.

90% - 2260
60% - 2150
50% - 1950

Jan's instructions show the speed at 100% throttle to be 2050, 50/1750, 30/1500, 15/1300 with this motor/controller.

Is it ok to run the Jive controller that low? I want to run between 1800 - 2100.

keepin' it real

hey stet off topic but how did you get the pyro 30-12 to work? i picked one up in germany and it has a 6mm shaft and the bolt pattern is different? i was thinking i was going to have to modify/make a new motor mount and redo the pinion?

The kit made for this motor had a different standoff that goes between the motor mount and the motor. The motor mount is the same, the standoff is different. The standoff is held to the motor mount by only two bolts.

I built this heli for a friend. On this one and on mine, the motor mount had both the three hole and two hole patterns. If yours is like this, you should just order the standoff from Jan. I will look up the part number for this standoff later today and send it to you by PM.

I am really anxious to hear if someone can tell me about running the motor at lower speeds with the Jive. I could not get throught to Revolution this morning to see if there is an 11T pinion available.

I am running the Jive 80+HV on low gov settings in my 700e without problem with the following setup:

Motor: Xera 4030-2.5Y 560KV
Ratio: 9.65:1
Battery: Outrage 10s 5000 25C
Gov smoothing activated
40% = 1620 RPM
70% = 1950 RPM

125 amp peaks are ok then I guess? They say 80 amps constant, but no callout for peak.

When you say low gov settings, you mean low numbers coming from the throttle channel, or is there a programming option on the Jive for "low gov"?

Thanks for your feedback. We will go with what we have and set the throttle to whatever it needs to be. Will try to change the pinion to 11T.

Low gov setting = TX throttle %

BTW, I've seen 135 amp peaks when really pushing it and I also use the Jive's BEC.

Set the heli up to my friend's 12X radio. Now running the throttle at 35% to get 2100 headspeed. Speed controller got warm only, not hot. So I guess it's all good, though I would like to get an 11T pinion.

I wonder if part of the reason we have to set it so low is that I kept the throttle trim tab all the way down when setting the fixed low/high points on the speed controller.

It runs really nicely.

so did you by chance ever find that part number? i tried looking for a manual for the pyro version but i never found it.. and revolution models didn't have anything.

The U-shaped part that goes between the motor and the mount is MP-1717

I have the same combo .. the pyro motor and jive controller. On the motor instructions it says the motor is fine run at low governor setting as long as you use the Jive controller. That suggests to me that the jive is fine at low settings

I figured since it was not getting more than warm, it should be fine. I think the throttle % settings are a bit arbitrary anyway and are just a signal value, not necessarily proportional to output. To drop the headspeed from 2260 to 2100 (7%) I needed to drop the throttle % from 95 to 35 (63%).

Eastwood, what headspeeds and throttle settings are you using ?

65% on the throttle gives me around 1800 but this is on a trex 700E

The jive works well at low settings but better to run at higher settings and change gearing, this way the motor has more RPM and will work better for you but still maintain same headspeed.

It sounds like the Jive was set up incorrectly and the position of the throtle stick is "off". I think it would be best to find someone with the same setting and check that persons settings with yours. By just playing with throttle curve, you can shorten the life of your motor/ESC/lipos. I could be mistaken since I don't know much about the Jive but with other ESCs, this potential problems would be a fact.

A bit OFF topic and I hope someones shared some of their own experiences. The same Jive 80HV, have you experienced any problems with spikes of 160 -180 Amps? The Jive is a solid ESC and it appears to be handling that OK but I was wondering if ANYBODY here has hear or seen a thread with problems due to high Amps.

Its called the Jive 80+ HV because with proper cooling it can handle double (160A) even more for short spikes.

I sometimes get rapid flashing upon landing and i asked Mike from Kontronik, it indicates the jive is operating near its limits, it means it was getting spikes near 240A.
This only happens if i fly really hard so i don't worry, the ESC and lipo is only 40C and the motor just over 50c.

Your are fine
