600 PlusInitially some shots of this outrunner:
Introduction
This outrunner is the new version of the Zpower Z30 which improves on both torque and cooling over the previous model. Century are marketing this motor under their own brand and it comes in the usual Century purple livery. This motor is aimed at flying 6S but within the testing I have also flown this motor with 5S and 4S packs. The motor comes with all the necessary bullet connectors and heat shrink to make it ready for installation. Running with a 6S pack the correct pinion is the 9T pinion. Fitting this motor was no problem at all. The motor bolts directly into both the plastic and aluminium motor mounts without issue. The only thing to be careful of is to make sure that the wires do not rub against the outer casing of the motor.
Where the wires exit the motor the edges of the hole are very sharp. I would strongly advise rounding off the edges with a small file. Extreme care must be taken in doing this as the metal shavings can fall into the motor.
Unfortunately, due to the above problem there is no detail (inflight graphs) of flying this motor on the smaller packs in this review. More on this later.

Flight Performance (6S)
This motor provides what I would term extreme performance on both 515 mm blades and 550 mm blades. This is one of the most powerful motors I have tried in the Swift and is difficult to imagine that more power would be needed for any manoeuvre that you wanted to do. Running on the nine tooth pinion the head speed is around 2150 rpm (unloaded). This seems a very comfortable speed for the Swift and going faster is not necessary.
I recorded some in-flight data running on both 515 mm blades and 550 mm blades. When using the 515 mm blades I did some tic tocs and the head speed varied between 2000 rpm and 2150 rpm. This is extremely good and the motor sustained this performance through extended tic tocing. When using 550 mm blades the motor showed little if any degradation in performance and the same manoeuvre yielded a similar set of figures for variance in head speed. The motor itself runs very cool and at no point in the testing did I find it to be what I would consider hot.
Below is the charts for 515mm blades:
As can be seen from this graph the flight time utilising a 4500 mAh Thunder Power pack is around seven minutes. The average tachometer for this entire flight was 2099 RPM. The maximum RPM being 2364. The maximum power produced during the flight was 1500 W. The average current across the flight was 33.38 amps with a maximum current of 72.55 amps. I think this data speaks for itself in terms of the great performance that this motor will deliver when running with 515 mm blades. For this particular test I was using the Rotortech 515 mm blades.
The next graph shows the in-flight data utilising the same pack but this time running M.S. Composite 550 mm blades:
As can be seen from this graph the flight time utilising a 4500 mAh Thunder Power pack is around seven minutes again. The average tachometer for this entire flight was 2049 RPM. The maximum RPM being 2342. The maximum power produced during the flight was 1534 W. The average current across the flight 36.24 amps with a maximum current of 75.98 amps. Again I think this data speaks for itself in terms of the great performance delivered.
As mentioned earlier I have also flown this motor utilising 5S and 4S packs. Whilst this motor is specified as a 6S motor it also provides an extremely capable performance when running on these smaller packs. Certainly a very spirited performance can be got from either 5S or 4S. I have some videos on the downloads page showing Adam Turner demonstrating what this motor can do with both 6S and 4S packs. Unfortunately I was unable to get some in-flight data to go in this review the details of which are in the conclusion below.
Pros
Awesome Performance
Cheap Price
Available direct from Century
Cons
Sharp edges can cut through motor wires
Can be difficult to buy due to demand
Conclusion
Overall I am extremely impressed with this motor. The amp draw is not excessive and well within the specification of the pack and the performance provided is more than enough for hard 3-D and some quite explosive flying.
There is in fact only one problem with this motor. This is that the hole in the motor where the wires come out for plugging into the speed controller has very sharp edges. After a number of flights I unfortunately had an incident where the sharp edge wore through the plastic sleeving on the wires and an electrical short occurred. This was enough to melt the wiring and render the motor unusable. Whilst this is quite frustrating it is easily remedied once you know the problem is there. My suggestion is that you either dull down the sharp edges with a file or sandpaper. Alternatively put some extra protection on the wires where they exit the motor.
My Rating - extremely highly recommended and the motor of choice for great perfromance in the Swift.
