Z30 or Z20 motor?

[LyNiX]

Hi every all,

I don't know if I have to buy the Z30 motor (1110KV) or the Z20 motor (1470KV) for 3D flight?
What about the flying time? The pinion?

Thank you!

Regards,
Jerome.

Hey LyNiX!

For 3D flight you need Z30. Go for latest Z30A version with new core. Fligth time surely decreses as you will get more power out of it compared to stock motor. I was told by Tom Viper, who actually tested power consumption, that Z30A is one fragment less power demanding compared the stock motor for same power setting ie. hovering. As you will fly 3D, power requirement will go up, but that is becouse it can and stock motor can't.

Flying time is depending on your blades, head speed, take off mass and manouvering.

Others will tell about the pinion as i only fly normal manouvers not 3D and 14T is enough.

I have been using the GAUI 1100 kv/1500W motor for a while,and since I always want to try new stuff I bought the Z30A also. I must say that it runs quieter with more power than the GAUI motor, but quite similar overall. Still not sure about flight time with Z30A with same settings (80 and 90%), seems to be similar also. The big difference is that Z30A runs way cooler, and thats nice. I will fly 10 more packs and compare with old logs.

Thanks guys!
I think I will buy the Z30A from flying-hobby.com :D

Bye!

Why don't try the zpower Z 20 980 T/V. It is a good alternative less power but long fly that the Z 30.
Here is the adress where i buy it :

LyNiX wants to fly 3D...

[badriM]

with the z 20 you have enough power for hard flying.

I have a Z30 on my raptor 550 E with one kg more that my hurricane and he have enough power for 3d.

Why use a z30 where a z 20 is enough ?

The consuption in max trottle of the z20 is 23A but for the z30 is 40 A.
If you have a Z20 you can fly 5 min in hard 3d with 2200 lipos but with Z30 you need 3200 mha for 5 min of 3d.

The weight is important the difference between Z20 and Z30 is 50 gr .For lipos the difference of weight is 200g between 2200 6s and 3200 6s. It is 250 gr less for my configuration and i need less power for the same result.

Another fact, if you have plastic frame, with the power of the z30 after some hard flyes you have craks arround the main shaft support. Don't forget also to change the gear for a hard one.

And finaly it is easy to balance the hurricane with 6s 2200 and Z20 but with z 30 and 6s 3200 it is not so easy .

[mkc2]

nicely said ,you got my vote !!!!!

[badriM]

Thanks mkc2,

Electric fly is quite difficult. It is not simple to have a great balistic fly with less consuption and moreover a long time to play with our hely.

For my Hurricane i find a good ballance with this configuration.

[LyNiX]

Thanks badrim...
So you said the Z20 980...is OK for 3D flight?
But I only heard about the Z20 KV1470...(from TOM VIPER)
What about the difference between the 1470KV and the 980? only the pinion ? :p

PS: i have carbon frame ;)

[tornet999]

I have the Z30A, and the benefit with that one is that I am using both 5s and 6s with same 14T pinion:
- 6s balistic power at 100%, 80 % nice for light 3D and longer flight time (7mns with 3200)
- 5s nice power at 90% giving me long flight time

I get longer flight time with Z30A compared to GAUI 1.5kW 1100kv motor, not much but maybe 5%. The motor runs cooler also.

[badriM]

It is simple,

If you have stock motor 800 t/v with 15 pignon teeth you have 1900 t of head speed.
If you have the Zpower 980 t/v with 15 pignon teeth you have 2200 t of head speed with more torque and best response of the cyclic with the same consumption that the stock motor.
To have a correct head speed you need a 10 pignon teeth on a zpower 1470 . I don't think where you can find it ?
The other problem is the global output of these two engines. With the 980 the motor turn to 21756 turn with 6s (theoretically). The 1470 motor turn to 33222 with 6 s. The global output of an electric engine is better when you have lower rpm, there is less loss in heat. The important is the torque to have constant head speed and with lower rpm you have more torque with the same engine.
Both of this two engines are good but i prefer the 980 with lower rpm and stock pignon.
In 3D fly this motor is ok and have a good ratio power/weigth/consumption.

badirM...

I am trying to decide what motor to buy... to run with my 2200 20C batteries. I am going to be doing hovering, FF, and eventually some basic loops and rolls. I am mainly after decent power for this style of flying... along with the longest flight times I can get.

I would like your opinion on this:

if I run a 14 tooth pinion with a Z20... versus running a 14 t pinion with a stock 850kv motor - the Z20 is actually more efficent and powerful... and so I can expect the same flight times on my batts... along with I will also have more torque and headspeed?

FYI - I am going to be using 475 woodies & 500 carbons for blades.

if you think this is true... I think I may have found the motor I want to get for my heli.

thanks - Brent

You use the 61t as first gear instead of the 42t, that will give you a perfect setup with either 14t, 15t or 16t.
I have used both the Z20 1470kv and the Z30 1100kv, there's enough power with the Z20 motor for most flyers, for headspeed chasers and really good 3D pilots the Z30 is a must!

The flight time is does not differs that much in normal and mild 3D flight, it's when you start using the tourqe from the Z30 that will shorten your flight time!

[badriM]

I am agree with Patrick.
For me, the best is to change the minimun pieces and save money for important parts, like have good servos and reciever.

If you use Z30 you have more torque and for the same head speed more consuption and more weight. Beware also of the cracks on the mainframe. If you use Z20 980 you don't have to change the first gear by a Revco one. You have less torque but less consuption and less weight.

The difference betwen the stock motor and a Z20 is the global output. With the same consuption the Z Power provide more RPM and more torque.

My hurricane with 500 carboon blades works very well with the Z20 980 for all basic maneuvres and madnesses. For the flight time it depend what kind of fly you expect. At full trottle you have 5 min of intense pleasure with 2200 6S. If you not nervus with your sticks you can expect easily 6 min and have long life with your lipo batteries.

[Hurriken]

In reading this thread, and others, I think I'm sold on changing over to the Z20-980Kv to replace the stock 850Kv on my Hurricane. I want a motor that runs a bit cooler, and I think the fan on the Z20 would do the trick, and sounds like my runtimes would be pretty much what I get. Only one problem! Cant seem to find anyone in the states that sells the 850Kv, I only find 1470+ at tppacks.com. Any ideas where I can get my hands on one?

[badriM]

I buy it in honk-kong on the net at this adress :

http://www.flying-hobby.com/catalog/index.php

Flying-Hobby is a very good store, after payement by paypal i receive my Z-Power in 15 days.

[Hurriken]

Ice man

Thanks for the info on flying-hobby. I ordered the Z20-980 tonight. Unfortunately it's on backorder, so guess I will see it when I see it. My 850Kv Gaui is still running fine, so this will just be a nice upgrade when I get it.

[bstock]

yep... me too. after studying lots of posts on that huge thread at RCG, lots in RR, and here on HF (especially in reading ice mans comments in this thread)... I also went looking for the z20- 980kv motor.

When I didn't see it on the tppacks website...I sent an email asking about it last night - but I have not gotten a reply back yet.

I also followed icemans link to Fung's website... and that motor is not cheap... but I still think I want it.

hurriken - please let us know what you think of it after you get it.

If it has more torque and the same (or simular) flight times as the stock 890... I am soo sold.

[badriM]

Hy guys,

It is shame if this engine is back order. That is the prof that many hely pilots have by it.

Tppacks is a serious US store. I have by a Lower Frame Upgrade for my raptor 550 e and receive it after 10 days.
I hope TTpacks import quickly this engine for the american Hurricane pilots.

It is great to exange our experience about our common hely and i have learn many thinks in reading the different post.

Have good WE of flying

Just for pleasure here is a photo of my Raptor 550 e

[LyNiX]

Thanks all,

I'll buy the Z20 980KV with 14T pinion and 42T front main gear :)

[Hurriken]

bstock I emailed tppacks also with no reply, kind of a bummer, I would have rather bought the Z20 from them, have heard good things about tppacks, but I go off the philosopy of you snooze you lose.

Well it must be that the Z20 wasn't too backordered they shipped it out on Sat morning. So I should see it in a couple of weeks. I'll report back what results I get, and through in a couple of Eagle Tree graphs comparing stock to the Z20.

[bstock]

hi Hurriken,

I also heard good things about tppacks... it does seem weird that they did not get back to us. I am thinking of seeing if there is a way to call them.

GOOD news on your motor shipping already!!!

Very cool that you have the eagle tree, and you will post data on both motors!! That is a nice surprise, and I am very much looking forward to it!!

thanks - Brent

I'm also in the mid of looking for a good motor for my Hurricane.

I have all stock setup and my flight time is 4:30min to drain my lipo to 3.7V/cell at rest.
Noticed that it bogged a lot especially while doing 3 continous stationary flip.

So my aim is to get a motor which can perform better than the stock and still having the same flight time.


After reading through many posts/suggestions, my choice is now Z20-980kv.

[Kepler]

I have come to the same conclusion that the Z20 is the best alround motor for this model.

BL, have you tried the shorter 475mm blades? I found there was alot less of a tendancy to bog with the shorter blades. Stability is also improved as the gaui 475mm blade is 80 grams as apposed to 500mm stock blade at 65 grams.
