As above, has anybody tried successfully using a Z-power? I tried to look in the "proven setups" section, it's all Neu motors. as much as i would like a Neu, but of course, the cost is the challenge :)

Any info would be appreciated! thanks!

Hello Shauntot.

Try to look in this thread, I started it asking for advice on ESC, but then come a lot of information on motors, mainly ZPower motors.

Quick answer: Yes.

I am currently running a Z30-1100 in my 6s Trex with a 15 tooth pinion. It runs great for me. I have a CC 80 Phoenix ESC.

This motor was originally in my old Raptor E-620 and I ran 8s (twin 4s in series) in that machine. Since I decided to scrap that heli, I moved the motor over to the Trex and was thinking about using 8 cells with my CC HV85 ESC.

I may do this in the future, but I'm still having fun with six cells, so will wait. The 4s packs are powering my Lepton.

csell - thanks for the link, very informative. although all the numbers got me a bit confused hehe

rocket man - where'd you get the 15t pinion? if i may ask, did you have a XL before that Z motor? how does it compare? was it also a direct dropin replacement, no mods needed?

I think Logo .07 mod pinions should work. They went with the finer cut gears a couple of years ago. I haven't tried yet but I have a z-30 1100 with a castle p-80. I'm curious too. What headspeed do you run and what aprox. time do you get? What blades are you using? Thank you for experimenting. TimT

I run Rev-Co pinions, available from Ready Heli. Adrian makes nice concentric steel pinions and I use them on all my helis.

I replaced a 600L motor with the Z30. It is a simple drop in, except for the pinion change. I don't have an XL motor to compare, but the Z30 runs quieter, and cooler than the 600L.

I haven't had a chance to tach the headspeed, but I calculated it to be the same as with the 600L (2100 - 2200). I run 600mm V-Blades.

wouldnt a Z30 (1700kv) be a nice combo with the 11t and 6s ?

i have heard you need to get some decent bearings for the motor. also the z power motors run good on the ESC with high timing.

hi chaps..wanted to revive this thread. i tried the link the csell gave above unfortunately it's now dead. was hoping to read up on the zpower motors as my XL just decided to snap it's shaft last Sunday after 14 flights only :(

need a motor asap as Align looks like they're not replacing my motor :(

was wondering if anyone specifically used this on 6s successfully?

Hello Shauntot.

I just checked, you are rigth, but now this link to the same thread:

I am sorry to hear about your XL motor. Unfortunately, I have now heard several horror stories about these.

Your link is to the Z30-1100, which is still flying great in my 600. I tried it as an experiment, but it has run so cool and so well, I'm sticking with it. As mentioned, I use a 15 tooth pinion and 6s.

I also have a spare Century 600+ sitting on the shelf. It is identical to the Z30 and should also work as well. I am considering a second 600 with this motor.



08-07-2007, 09:32 AM
thanks for the link again Carsten. I think it died when the forum changed "looks" :)

hi rocketman, glad to hear about your z30-1100, i'm also planning to get this to replace my dead XL. what pinion are u using 15t? i also read the century plus motor is the same as the z30 "A" (which is the blue), newer version. how's your trex flying with the z30? care to show some vids or graphs? really interested :)

Hello Shauntot

Here are the 3 links from my thread, to websites for Z30.




Yesterday I cut holes in the side of my CF frame to make room for a Z50, have you considered to do the same?

It was easier than I expected.

Regards Carsten

hi carsten, sorry don't see any links :)

haven't thought about a z50 yet, was only planning on 6S and nothing higher...so i guess z30 will be ok?

Unfortunately, I fly alone most of the time, so don't have any vids. I don't do spastic 3D, so a vid would be boring with me just flying around doing loops, rolls, and piros. I will hook up the FDR again soon to see how my system is running and will send you the graph.

So far, I am quite pleased with the motor on 6s. I originally did the switch thinking I would go to 8s (12 tooth pinion), but haven't finished the swap. (I have a CC80 on this bird and would have to change it to a CC HV85 in order to run 8s.) The HV85 is sitting on the bench; I'm just too lazy to swap right now.

AFAIK, the Century 600+ is identical to the Z30A, except for the color (magenta vs. blue). If I get the second 600, I will try 8s since I have a few extra batteries sitting around.

Take care,


08-07-2007, 07:51 PM
thanks rocket man, so i guess i can get any of them either the z30A (blue) or century plus (magenta), so as long as it's not the old z30 (magenta) right?

for my flying level, the XL is already ok, i just want a motor that I can trust without the shaft snapping!

btw, would you know if the z30 or century plus is alright with the stock 75a esc on 6s?


08-08-2007, 10:49 AM
this is what i'll probably end up getting..hope it's gonna be good on 6S...

My last FDR file shows a high of 62.6 amps so it should work okay.

Unfortunately, I really splashed my 600 last night. The heli came in straight down from about 100 feet and splattered all over the field. There was carbon fiber raining down for a long time.

Anyway, the heli is pretty much toast. The battery landed about 30 feet away - it was crushed but didn't burn (thank God), the Z30 was crushed, and just about everything else was either bent or broken. The force even sheared off the little head button. I looked it over last night and the main bearings are okay, so are the tail rotor grips and blades. That's about it. It will be a while before I get this one back in the air - might be cheaper to get another kit. I've never destroyed one this bad.

Oh well, life goes on.


08-08-2007, 11:19 AM
youch! sad to hear Ron, do you already know what caused the crash? hope u get her back up in the air in no time.

sorry to sound insensitive, but i just wanted to ask if you knew what your headspeed was using the z30? i used readyheli's online headspeed calculator, using a 16T pinion and 6S will only give me around 2025 headspeed. 17T is the ticket, will give around 2200 headspeed.

of course these online headspeed calculators are for baseline reference only as a lot of other factors will affect the headspeed, but was just wondering what HS you had when the heli was still alive.

again, good luck with the rebuild, may the align force be with you :)

It looks like pilot error. :-) I just changed this heli from my DX7 to the PCM10X and the collective stick is much tighter on the 10X. I'm afraid I just didn't move it fast enough.

I was getting about 2000 on my 600. As you correctly state, there are so many variables here. The only calculator I've seen uses the straight reference voltage, which is too low. We generally prefer to use 3.9 volts per cell here at work, instead of 3.7 volts. Our calculations come out much closer to reality with this voltage and it follows the actual Li-po discharge curve better.

The best tool is a tachometer and that's generally what I use.

If I do this again, I will try a 16 tooth pinion, too.

Take care,

Hay guys check this site out talking about z power in the trex 600. This guy Phil Lennert has built a trex 700. http://www.microheliworkz.com.au/rotortips/index.php

08-08-2007, 06:41 PM
thanks Ron, looks like i'm taking the plunge on the Z30 and a 16t and 17 pinion to experiment it out. I just hope it's correct on 6S :)

thanks for the link aussie, unfortunately this guy's running 10s on z30, what we're after here is z30/z50 on 6s power :)

08-08-2007, 06:56 PM
I will be trying this one for my trex600
It is a bit heavier than a z30, so I hope it will run cooler with more punch than a z30.

Hello Shauntot.

I don't know much about the ZPower Z30 as I choosed the Z50.

But all the webshop I previus gave link to describe the Z30-1100 to be used with 6s lipo.

And here is the link to ZPower: http://zpower.tw/ch/php/product.php?page=product/z30series.html

I don't know why the webshop you found in Hong Kong write 6-8 Li-xxx. But in a post in my long thread kgfly gives the information that in a part of Asia they are flying T-Rex 600 with Z30. Can it be in Hong Kong?

From my long thread post # 92. Quote: " Tppacks, who are marketing the ZPower motors in USA had just posted this answer: The Z30A is a bit small for 600 blades, in my opinion ".

But RocketMan is very happy with his setup, If I was you, I would try it. If then after some time you want to change some thing, you can consider to try a little smaller rotorblades.

If it is very importent for you to get the new design of the ZPower motor. I can tell you that the way to find out wich version you have of the Z50 is to se for the Io @10V(A). It is considerable less for the new design.

Bjorn, the ZPower weights are Z30: 280g and Z50: 340-348g.

And the new Z-Power Motor 1150kV is in stock at mikado,

LOGO 500 3D Rotor blades: 500mm/520 mm acording mikado website.

Acording to this norwegian webshop:


Specifications ( temporary ):

RPM/Volt: 1150
Type: 8-Pole outrunner
Vekt: 340g
Diameter: 48mm
Akseldiameter: 5mm

There are something that I do not understand here. As I se it, they take the Z30
specifikation and mount in a Z50 housing, it have the size and even the weigth
of a Z50, and it is to wide to fit a T-Rex 600 frame without modification.

I am wondering if it is a Z50-1100? but the Z30 is has power enough for
a LOGO with 500mm blades.

How can people consider publish this as temporary specifications!!

We can only consider this webshop and its product when they suply
decent final data and a release date.

If you look for a ZPower 1100KV, Have you considered the Z30-1100,
It even fit the T-Rex 600 frame without modification,

Regards Carsten

Yes, I have looked at the z-30 1100kv motor, I have one in my roxxter 33.
I also know I will have to modify the frames, and nobody has ever said that the mikadomotor I will be trying will fit the trex600 without modification.
The Norwegian webshop has only written the data received from their supplyer, an there is nothing wrong with that as long as the put on the website that it is temporary spec..
I believe the z30 on 6s may be a bit to small for my flying, and I just wanted to test this one.

Hello Bjorn.

On http://mikado.e-vendo.de/e-vendo.php?shop=k_mikado_e

If I seach: Z-Power Motor 1150kV

It shows Z-Power Motor 1150kV
Item no. 05000
available within:: 1-2 days to 159,00 EUR

There is no specifications, but may be they can suply more informations?

I had just choosed the Z50-800 to try in a high voltage a123 setup, and
last monday I maked room for it in my 600 CF frame by cutting in it.
It was easier than expected. In post # 124 in this link is pictures:


You write you just want to test this one, nice idea, please tell us, how its perform,
it is by people like you new setups is developed.
