e-Align T-REX 250-450-500-600 > T-REX 600 Century 600+ motor for trex 600

Wondering if the Century 600+ motor would be adequate for a Trex600. Dimensionally they are the same. And both are capable of approx. 1500 Watts of power.

From my understanding the century motor is essentially a Z30 and very efficient.

I want to use 6 cells, but still get decent power and flight time. I am no 3der yet, but loops, flips, and rolls are not too far in the future.

any help is appreciated,
Dave

NOPE....

Won't work....the Kv of the Century is too low...it's only 1100kv...it wouldn't be enough on 6s for that machine...

I've heard bad things about century/z motors pooping out after 30-50 flights (only hearsay though). I piece of advice i can give you though is to run higher voltage, it will make your entire drive system more efficient and last longer (motor/esc/batts)
Try 8S or 10S and pinion down until you get nice sport headspeed, that way you'll get long flights due to the efficient system and you'll go easy on your equipment. A HV 85 would do fine on a trex 600 along with a scorpion 40mm heli motor perhaps. Just make sure the motor is capable of lower headspeeds by lowering pinions now, but if you'd step up 2-4 pinion sizes you could have high performance later.
A misconception is that only serious hard 3D flyers need to run high voltage but its great even for beginnners because of the above reasons. 6S on a 500 stresses everything pretty good just because of the low voltage/high amperage combination. I try to keep all my electrical systems to average at least 1:1 current to voltage
for example for my trex 500, 22 volts to 22 average amps (with peaks to 45ish)
this is just a benchmark i use but seems to yield good results. I have a plane that is over 1:1, that is 22 volts to about 20 amps average (again, peaks to about 40 amps) . Everything runs very efficient and very cool, windings,magnets, fets, all last longer and run cooler and more efficient at higher voltage.
sorry, kind of wrote a novel there.

My blade mCX can outfly your Aurora!! (in a 1' x 1' x 1' box) :)

I'm sure JAG will agree with me on the high voltage stance...

High Voltage

I agree 100%....not only will you get WAYY more power...but things run cooler and last longer for sure...

I agree that higher voltage will make for a cooler running set-up. I would like to stay with 6s due to charging limitations.

With the century, could I not up my pinion to accomodate fort he lower KV?

I’m flying a Z30 1100 kv with a 15 tooth pinion on 6s. This is a very nice setup. The Z runs very cool.

X30,
I sent you a pm with a few questions. What kind of flying are you doing with this set-up?
