After approx. 40 flights my 11S Neu 1521 powered ugly Ion-X :) (Mille canopy) continues to pull like a mutha with no signs of wear on the sec gear. This makes for about 120 flights total on this gear which was installed with the motor and run on 10S for about 80 flights last year.
4 minutes is the magic mark with consistent performance from start to finish - after flight the ESC is cold and motor warm, but not worth temp'ing. It just works.
Learned something recently... the machine developed a intermittent tail twitch a which would show only under heavy load like a sudden collective change. At first is seemed like something in the drivetrain slipping or failing gyro sensor. Checked out the drivetrain, replaced the sensor - no difference - was about to replace the ESC with another HV-110 when I found the problem - a worn, pitted deans connector on the ESC. Changed the connector and problem gone.
The power is ADDICTIVE.
Where is my Ion-X2??!! :D

I have the same thing on my Ion w/HV110 w/611. Never thought to check the deans... :D

Lucky you...
My Neu experience is 0-3 so far, 0 have held up, 3 have the shaft slipped...
However, I have high hopes for their new H line thats coming soon.
Interesting on the dean issue, thats worth writing down on the "check from time to time"
Where is my Ion-X2??!!
Got a mail from MA the other day where they said it wasnt far off now :D

Hey Dan,
it was the last place I thought to look but after changing a bunch of things (t/r servo, gyro sensor, gyro) I remembered something I'd read here and took a close look at both the ESC's connectors. The one that's always connected last (with the big spark) before flight was pitted - didn't look like much, but I changed it anyway and problem solved. This was the second season for these connectors so I guess they can be considered consumables.
MrMel - lucky me :) - we'll see how long it lasts. X2's close, good - already on backorder at my LHS

I too have been having some issues with Deans Ultra Connectors lately, I am going to change to 5.5 or 6mm bullets and be done with it.
Glad to hear you are having fun Rob!!

I too have been having some issues with Deans Ultra Connectors lately
Same here, it seems as if the spring contact on each prong of the connector has gotten thinner. While this does make the connectors easier to take apart I've gotten a few that were way too loose when brand new and have also had the springy part bend/fold/deform destroying the connector. Some are fine (old style) out of the pack, some aren't. I hope this was just a bad production run.
There are also fake Dean's connectors on the market - the plastic connector body is a darker color red than genuine Deans. They seem to be ok for use as charge leads, but not much more - definitely not for high current applications.
Glad to hear you are having fun Rob!!
You have no idea man :). There's one only reason why there's still PowerMaster fuel in my garage these days and it starts and ends with "A".

One word: Powerjazz!
Spark-free!

HAHAHAA I hear that as well Rob. I too am looking forward to mine as well. ;)
PowerJazz?? Are they available now?

Not only available, actually fair price at esprite, I run them in both my .90 sized electrics.
Only thing is that you need the progcard as well, which the US resellers seems to have forgotten.

Thanks for the Pic!! NICE!!
:smokin:
Yes the PowerJazz rocks :-)
This is the best 12S+ controller I have tried so far, works 100% all the time. And with this controller it doesnt matter (more or less :-)) if you have 10-11-12-13 or maybe 14S as you just dial it down...50% part load is no problem for this controller.
At the moment I am running 12S FP 3700 EVO20 cells with the NEU 1521 1.5Y and a 50/52T secondary gear in my Ion-X.
It works fine, the trick is just to dial it down where the gears will last, and the free bonus is a very stable head speed.
OK, pitch have also something to say, but at the moment I can get the 50T and 52T secondary gears to last long enough with the throttle curve set to 60%, which gives around 1850-1900rpm on the head. If I go just slightly aboce 60%, lets say 63%, I am already in the danger zone to strip the secondary gear...so it is a very fine ballance between where it will last or not last...and the PowerJazz is the controller there can tame the power from the Evoīs and the NEU :-).

Yeah, the powerjazz is truly amazing that way, you can even go under 40% throttle without ill-effects. (40% of the governor RPM range, not the whole range though)
No "CC-surge" at all.

That powerjazz is a nice looking controller. Does it really need the active cooling or is this application dependent?
The 110's have been working very well in GOV mode (no surging ;) ) - the gov. gain settings were different for both motors (20 for the Actro and 16 for the Neu if I remember correctly). It would be nice if the factory setting were closer to values that are known to work well for popular motors, perhaps 20 something.
PDC - Looks like I got the magic secondary gear too ;) - there seems to be no end to that sucker... I'll be sure to post the day it lets go :).
At 1930 on the head the 11S Neu is VERY impressive, so I keep that setup in idle 2 for WOW factor when asked. I have taken to using 1840 something for everyday flying as it is easier on the batteries, results in slightly longer runtimes and more 'practical' flying, but still pulls strong - prob. feels like my SZ's + 10%.
Power aside, my lightweight 10S Actro 32-3 Ion with 3700 EVO 20's is probably my favorite e-heli right now - maybe 'cause that lightweight setup rocks ...or it could be that the Neu Ion with the makeshift canopy is so damn ugly :D.

Just for info!!!
Havent used the Actro 32-3 motor for a long time, and last time I used it was with an old technology battery, so put back the Actro 32-3 motor after a long time with only the NEU motor, just to compare, and after one flight only I came to this conclusion.
No restricting secondary gear = less noise and more power.
After only one flight I am not afraid to say that the 12S actro 32-3 setup is superior in noise and power to the NEU setup with the restricting secondary gear.
Time will as usual show for how long time this setup will last.
And again, the PowerJazz is a good friend here, started at 40%, then dialed it up to 50% where I had already very good power.
:D

you should try the new Actro MAX, its even better :)
Those germans surely know how to make stuff.
Merklin (german quality hobby train builders) have come up with a new brushless motor with "twitsted" magnets, it should be very efficent and powerful, so I think we will soon see better and better motors.

:D That's a bit funny you say that, as I just half an hour ago finished moving my 32-3 MAX actro from my Joker 2 over in the Ion-X...so tomorrow it will be with the MAX version :twisted:
By the way, the main reason I can have more power with the Actro motor is that I don't have a secondary gear anymore to limit the power I can take out before the secondary gear is stripped......now the new limit might be the primary gear ;-) but if so, what I don't expect, it will be a stronger weak link :-).
And as said, the noise level will be lower without the secondary gear.
The TOW including everything and a 12S3700ma EVO20 battery is low, only 4.96 kg or 10.9 lbs....giving 5 minutes of real fun would be my very best guess.......we will see how it works tomorrow....and it should be good weather over here ;-).
Looking forward to hear some more about that Merklin motor..yes, know the Merklin trains....have been out there for a very long time, at least I remember the Merklin trains from when I was a little kid.
PS. on top of the motor one can see my "Torque absorber" ;-), as I expect a lot of torque from this setup ;-). Itīs one of my Swedish friends who made it for me.
