It's the "Z50 black" tested by TrexTuning.

Had to remove some of the frame material below the motor mount to accomodate the motor!

The Zs are great motors, but they have one fatal flaw. The only thing that holds them together is magnetism. If you pull on the case they will come apart.
There is no mechanical device that holds them together. This minor flaw can be resolved by securing a Trex 450 shaft collar against the front bearing.

Doesn't the pinion stop if from coming off?

Really- well, maybe the way my motor is acting is "normal", but if so that sucks because it allowed the shaft/rotor to move down while doing tic-tocks and chewed through the main gear (neatly removed half the width of all the teeth!)

I am going to pull the motor from the heli today. Maybe I can save myself some trouble by putting a collar on there as you say.

The pinion is up too high to keep the shaft from moving down (on the Trex 600 anyhow).

Never, ever, ever, ever give up.

I use small washers as shims between the bearing on the motor and the pinion to stop the motor seperating! Learnt the hard way.

Freakin' heck... why doesn't someone tell me these things...

A trex 450 shaft collar fit perfectly up against the motor bearing, then put on the pinion and its all happy now. I put on a new main drive gear and she's ready to fly again. Very happy with that.

I think ZPower has to include some instructions about this sort of thing. Probably they use locktight to mount the shaft into the bearings, but its not enough and a little heat from operation melted it out. All it cost me was a main gear, thankfully.

Not going to send it to HeliDirect now, no point.

Never, ever, ever, ever give up.

FLew 5 packs yesterday afternoon after putting on that collar above the bearing- no problems now she's back and flying great.

Now I wish I could get my lipos to last longer (TP pack will now only go about 3.5 minutes before the power really drops off. I think it has about 50 cycles.)

Time the flights to 5 minutes, and I never put back more than 80%. I think I really need to go to an 8-cell setup.

Never, ever, ever, ever give up.

I was so impressed with the Z20 on my Hurricane I purchased the Z-30 for my 600, but I have not installed it yet. I understand your running a 16 tooth pinion, what kind of head speed are you getting using this combination with the Z?
What motor pinion combination were you running before you install the Z and what was you head speed in that configuration?
I have 2 EVO 5000s that I have been running on the Trex 600 with very good results and no drop off issues. I have about 5 flights on my X-cite 5000. With the X-cite I pick up 70 rpm on the head over the EVOs.

I am guilty of never usinga tach on my helicopters, so I can only talk in relative terms.

Originally I flew a 600L motor and 10T pinion, and it was pretty good, but I was not pushing it terribly hard.

I flew that motor until it seemed to get degraded and did not produce good power. I installed a different L motor, it was very good, and I flew that one a lot (10T pinion still). Then the top bearing on that one went bad, so put in a 1650kv 600XL motor, which shortened the run times, but gave okay power (not that much more than the L I had just been running). That motor shaft sheared after approx 15 flights, then I temporarily reinstalled the old-old L motor, and ordered the Z30A.

On 16T pinion the Z30A gives the best headspeed by far and 5 minutes of 3D and I'm right at 4000mAh put back into the pack. I might shorten the flights to 4:30.

I put in ThunderTiger green paddles in place of the stock ones at the same time I installed the Z30 motor. Man, the cyclic is very fast now.

This is not unlimited power. It will bog doing continuous flips, or if you try to speed up the tick-tocs too much. I have a hodge-podge of packs, the newest is a TP 5000 V2, its great, but gets pretty warm. The older TT V1 is just in the last few flights suddenly performing very badly. It has about, oh, 50 cycles-- I think I'm going to send it back to Thunderpower, and my two FlightPowers are going back to them both are doing badly and have less than 80 cycles.

The Airthunder is doing well still, but not as powerful as the TT V2.

I recommend you consider the Z50, 1170kV version- might need to order it from the UK though.

Never, ever, ever, ever give up.

My current setup is the Align 1650 KV motor with the stock 10 tooth pinion and the TT green paddles. I had planned on installing an 11 tooth pinion but with the EVOs I am getting 1980 rpm and with the X-cite I get 2060 at 100%. I have my timer set to 5 minutes and buy the time I end up back on the ground I have flown 5:30 to 5:45. I have been putting 3.5 to 3.8 amps back into my 5000s. Currently I am very pleased with the way the 600E flies, but with the Texas summer coming I wanted a cooler running motor. I already purchased the Z-30A 1100KV and may try a 15 tooth first as I am not looking to boost the performance at this time. Hopefully I’ll have time to install the Z this week

RE Lipos lasting longer.
I'me using CSM revlocks on the 600's. 1950 headspeed with the z50. Smooths out the amp draw and reduces throttle more, than curves, in low motor load situations. Without the revlock I hit the low voltage, 3.2v - replacing about 85% pack capacity, at about 4.30 minutes. With the revlock comfortably fly for 5.20 and use less than 80% capacity.

I had wondered if governing the throttle would be a benefit- seems like it should and your experience backs this up. It would be good to balance the power better- its more than I need at the start of the flight, but tapers off too much before I am ready to land. I am running nearly a flat throttle curve and haven't dickered with it much at all.

Is the Align ESC gov function any good? Might be worth a try.

I run the 16T pinion, 15T should be better flight times for sure.

Well there's always work to be done.

I flew 3 flights on the Z-30 powered 600 today. It was 84 degrees when I flew. Using the Z30-1110 KV motor with a 15 tooth pinion the head speed was a least equal to or better than with the XL and a 10 tooth pinion. The Z also seemed to bog a little less than the XL during hard cyclic maneuvers. Each flight lasted 5:00 to 5:20 minutes and at the end each flight the battery temperature was very similar to what it was with the XL. I put 3.42, 3.63 and 3.51 amps back into my 5000s. The speed control was remarkably cool and the Z was quite warm but not hot like the Align motor. I could hold my fingers on the Z indefinitely. If I had grabbed the XL like that I would have been scarred for life.
I am quite pleased with the Z; I will possibly switch to the 16 tooth pinion in the fall.

The Z30A-1100 is an excellent choice. I flew one for a while and still keep it for a spare. The Neu is a little better but the Z30A is a good low cost choice.

Well I need to post some bad news, and I'll get some pics to add later tonight.

The Z30A motor failed after a flight last Friday. Weird because I put a 15T pinion on it, trying to ease the strain on the 6S packs when originally flying the 16T pinion. The HS dropped a bit on the 15T, not really much difference on the battery temps, so I don't know if it was the right direction to go.

End of the flight (planned), auto'd to landing after my normal 5:00 minute flight. I picked up the heli and couldn't turn the rotor against the motor rotation- the motor seemed locked tight. Couldn't figure it out there, so when I got home I dropped the motor. All the magnets seem to have broken free from the rotor housing and jammed up against the winding core- locked and dead for good. Very strange that it seemed to happen as the motor was shut down to do the auto landing, and the landing was pretty normal, not bone-jarring.

I have always let the motor cool between flights, and use about 3800mAh in my flights average, so about 46 amps average pull, I guess peaking just over 100A from the datalogs that other users have shared. I am disappointed that yet another motor gave up its ghost before 100 flights. I am not sure at this point if I will upgrade to 8S, or just sell off. Its discouraging to say the least.

Probably save for an 8S setup, or sell and get back to it later, or just move on... poo.

Never, ever, ever, ever give up.

Sorry to hear you trashed your Z
I have about 60 flights on mine and after reading your post I decided to pull mine out for inspection. The first issue I ran into was that I had difficulty pulling the motor apart.
There were two problems, the first was that I had added some Tri-flow to the bearings and that oil baked onto the shaft making it difficult to split the motor. The second issue is that the inside of the stator was at a very slight angle to the front of the motor. This put additional loads on the bearings that scored the shaft inside the motor.
I am going to replace the bearings and put the stator into a press to square it up.
I had pushed the Z-30 very hard last weekend flying it in the Texas heat 3 (97 F) days in a row. I wouldn’t have even considered dong that with my XL.
Tomorrow I am going to try out The E-sky motor for the E-smart.
It looks remarkably similar to the Z and weighs 27 grams heavier with a cool looking fan.
The motor cogs much harder than the Z and is advertized as being 1200 KV

this type outruner motor is not good enough.the reason as follow:
1.can't balance the rotor.cause short bearing life.
2.just 1 point support. the under bearing is no use.bearing damage fast.
3.the rotor is outside,it's not safe enough.
seem the ALIGN's motor is better,but they make a mistake.they didn't put the under bearing in the back cover directly.the intallation error cause the bearing not in line.so short bearing life.



When one day you can manage hover,the sky is your home!
