Synergy E7 › e7 With Scorpion 4525. What is the best setup?

I know this is a popular motor and I am looking for advice from experienced users. I am setting up a 2nd e7 with a PowerJive and Scorpion 4525-520 combo. I am running the standard e7 gearing (not the SE gearing). I would like to run somewhere between 2000 and 2200. Less bogging and more torque is more important to me than overall headspeed, so if there is a sweet spot for this combo, that is where I want it. What pinion should I run and what % throttle curve should I expect to run on the Jive to get a proper governed headspeed? I am just looking for a general idea or starting point, I will use a tach to set the exact throttle % once it is flying.

Would I be better off switching to the new main gear? I would rather not swap now, I have 2 older maingears (116t) in perfect shape along with pinions of every size. If the benefit is really worth it I will switch, but if the difference is not dramatic, I would rather wait until I strip/ruin the ones I have.

Any info is really appreciated. This is my first Kontronic in years so any tips will help. I can make guesses using headspeed calculators and have a general idea where to start, but I would rather hear from people with real world experience using this motor in their e7.

no need for the new main gear, it was designed with higher kv motors in mind. i would start with an 11t pinion and set your throttle to 90% see if your happy with that, if not then try a 12.

Mr Mels HS calculator is the best and easiest I have found

Let me know if you have any Jive questions, im a Kontronik guy

ps: if you want another main gear someday let me know

My original e7 has an Eflite 520kv motor and I run a 12t pinion. I run throttle curves (no gov) & an 80-90% throttle curve with 10% cyclic/throttle mix which gives me ~2000 rpms. It runs very powerful like this. I thought similar gearing with the Scorpion would put the Jive in a good spot for gov mode. Unfortunately I don't really know because I haven't tried it and I have never run this specific motor or ESC. If 11t is enough for proper governing, I don't want to over gear it with a 12t. I just want to get the most out of this motor/esc so whatever works best and keeps the motor in the optimal range.

I am running 12s 5000 packs. Looking for 4 mins of 3d flight and reasonable temps for a long term running motor/ESC setup.

the calculation i used was a 12s pack 116 main and 11 pinion. this gave me 90% with a jive @ 2100HS

if you have an 11 i would try it first, then switch to 12 if your not happy

Is there a sweet spot for the Jive for best gov performance or does it depend on the motor. Should I be shooting for a 70%, 80%,90% throttle output? I have enough pinions to make the motor run in some different rpm zones for a given headspeed. Is there a sweet spot for the 4525 motor or Kontronic ESC?

Would I be better off with the Ice2 160? I run 5 Ice controllers in other large helis and I am pretty familiar with them. I would like to try the Jive, it seems like a waste sitting on a shelf although if it doesn't get used now, it will just be in the next project.

80 to 90% should do you just fine. a little above or below is ok, they don't seem to be super picky. I think you might want to switch those other 5 once you get this baby singing

I don't think that 11 tooth pinion is available for the e7

I am not sure if they make an 11 tooth pinion or not for the old style main gears (which is what I have in both helis). My eflite motor is also 520kv and I am running a 12 tooth pinion with an 80-90% curve. My logs show the headspeed is right around 2000. Most setups I can find from old posts seem to be using a 12 or 13 tooth for this motor/heli. I am hoping to get 4 mins of flight with the 4525 so I will start with 12 tooth and hope it puts the motor/esc in a good spot.

I agree with dyecocker1 on 80 to 90% for the Jive, that will keep it running best and coolest.

BTW, Jives yield a much higher and lower RPM range compared to a Castle with the same motor and gearing.
Some folks go down 1t on pinion when switching to a Jive.

here is Mr mel calculator link:

I would use the 12t pinion, as there was never an 11t available. This would give you 2150hs at 70% on Jive with calibrated end points. This is on 116t main gear.

With a 121t new gear and 12t pinion, you could run 75-80% setting on Jive for 2120-2180hs.

As others mentioned, play with MrMel Hs calc program.

Thanks for the advice and link Santiago, I couldn't find MrMels calculator after readyheli shut down. Thanks 4cyclic for posting the numbers. Looking at them, I understand the reason for the new main gear. Has anyone ran the 4525 on both size main gears? If so, did you feel any difference in power delivery or lower temps with the new gearing? I have heard this motor's sweet spot is around 85% output although I don't know if that is accurate or not since I don't fly with anyone that runs it. There is a lot of conflicting info when I search the forums about this motor and ESC so I am not sure what to shoot for.

I ran both, and did not notice a power difference, however the new gears are quieter. I was running 2150hs then dropped to 2050 for new gear ratio. Seem to have same pop as before and I'm getting slightly better flight times.
