latest motor comparisons? Z30, RCP, Scorpion etc.

[concept1]

I started this threat for the 3D performance guys, NOT the beginners. It has been a while since we have gotten any motor comparisons and I know some people have been trying different HOT setups lately. so how have the motors stacked up for all you guys who HAVE TRIED different motors? Have you been lucky enough to find one that really stands out for Performance with efficiency?
I Have been flying my Hurri for roughly a Year now and have tried the stock motor, RCP H/18, Scorpion 1000kv, and currently running the Neu 1907-1.5. I have run 6s lipo, 7 s A123 8s A123, 9s A123 and 8s Lipo.

For starters the Scorpion was a huge dissapointment, although it would be a great starter motor not for a performance minded flyer even on 8s A123 though. I would say it is better then stock but barely.

I still liked the RCP the best it was a bit power hungery and many guys reported problems with theirs, mine never ran hot and performance was great! I only started testing other motors because I was hopeing for longer flight times on A123's,

the Neu is very efficient and very cool running, 8s Lipo you better hang on, I just prayed my Hurry would not blow apart in mid air! I only did this test because I hadn't made up any 9s A123 packs yet.
on 8s A123 the RCP has more power, but I get almost 1 minute longer flights with the Neu.
on 9s A123 this motor works very well with it's lower Kv, but I only have a few flights on 9s and my thoughts are back to I want to stick with 8s or maybe 7s for simplicity sake! but for a higher voltage setup this motor is worth some more testing. I should easily be breaking into the 5 minute flights with this motor and have good power for anything,

comming soon I just ordered a Z30 and I am very currious to see myself how this motor stacks up! I have heard may guys who had the RCP went to the Z30 and claim it had same power with longer flights. I also would like to hear how the other Scorpion motors Fair in comparison the 1400 and 1600kv's with the Z30 or RCP's

has anyone broke the 5-6 minute mark on A123's with a hot setup?

I can't speak to A123, just 6S lipo. I've tried the H18 and the Scorpion -1400. The Scorpion -1400 has a lot more power than the H18 and uses about the same mAh for similar slight times. However, the Scorpion runs hot (157*F) and it makes the batteries run hot (135*F) too. I haven't tried a Z30 1110kV yet. Definitely want to get one when it's available. I have a Scorpion -1210 and another H18 coming. The -1400 may have burned up my 20T OWB.:wow2:

well i havent tried anything but the z30 and i am extremely pleased with it... i fly with 2 3cell 3300s and get about 4:30min of flight of nonstop pushing this heli... i could go more but i prefer to be safe. i set it up with 15tpinon 50t front 20owb and 60main for around 2500 rpm and i was pulling 2470 but because of the hot summers i was pulling 2600rpm at 95%tc and after my flight with 100degree outside temp the batteries are around 115-120 and the motor is warm but doesn't burn your finger and esc is the same. i would believe you could do 5min on 3300s but i prefer to be on the safe side and you can ask my buddies at my field i push this thing hard and for the entire flight... the only rest it gets is hovering inverted lol... with the z30 make sure you put the 450 main shaft collar on it so the motor doesn't come apart and dont look back :)

Concept1: can you elaborate on why the Scorpion motor 1000Kv is a disappointment?

I have flown mine with the RCP H/18 1100 Kv, Z20a 980 Kv, and the Scorpion 1210 Kv. The Scorpion motor is the best motor that I run so far (I didn't want to go to a Z30 because I did not want to open up a big hole on my FG canopy)

With the stock gearing (13T, 42T, 20T OWB, and 61T) this motor is running around 2400 rpm at 90% TC on a set of FP-EV30 3200mA packs. The motor does not bog even in fast tail down tic-tocs. At the end of a 4:30 min flight, the motor/ESC/battery temperature are around 130F.

I elected to go with a slower headspeed by swapping out the 42T for a 50T and up the pinion to 14T. With this combination, the Scorpion motor runs at 2200 rpm at 95% TC. The motor still does not bog even when I tried to pump collective really hard. The interesting thing to note is that the motor temp is now around 125F, battery at 125F but the ESC temp at 145F. I guess the ESC is getting warmer because in order to Scorpion motor to run smoothly, I have to reprogram the Align 75A ESC for high timing. Flight time now is around 4 min and 45 secs.

I was able to consistently pulling 65+ amps out of the packs (1300W)

Concept, have you tried 9s lipo yet? you can easily fly 5-6 min 2400-2500 head speed using up only 2000ma. 10s A123 at 800grams was too heavy compared to the same power as a 9s 2500 620g. The best flight pack I have is the Evolite 6s+3s 2500 = 550g. I am using the Z30 older version rebadged by Thunder Tiger. I wonder how much more efficient the new Z30A? Since your running higher voltage you may consider trying the Z30A 800kv instead of the 1100kv.

Hi!
I've been running 7s and 8s A123 and 5s and 6s lipos. I tried Gaui 1100kV 1.5kW, Scoprion HK3026-1600kV and TT OBL 43/11 (similar to Z30) with 1100kV.
The OBL really has a lot of torque... much more than anything else I've tested. But power consumption is the same as with a Gaui motor. The Scorpion doesn't have this extra kick like the OBL, but power consumption is much better and you get around 20% more flight time...
A123 isn't the right think to get a lot of power... my peaks hardly ever go above 60A. I testet today with my new 2x 3s 3300mAh 30/50C SLS ZX lipos. This was the first flight with these packs and I've done pretty much the same maneuvers... there's hardly any bogging at 55% on a 80A Jazz. With 75% you get some more, but performance is really great! I've used the same setup with A123 and 6s lipos, 8s A123 == 2150rpm and 6s lipos == 2000rpm... peaks with A123 around 1250watt and 6s Lipos around 1850Watt. But I've to say that these lipos are brand new, first flight!
Flight time with A123 == 3,9min, 6s 3300mAh Lipo == 5min with 20% as backup.
Weight is another issue... these 6s Lipos have 100g less against 8s A123. It should be possible to use 4000mAh 6s with 30c and get around 6,4min with the same weight as 8s A123... I'm using the 8s A123 packs for training flights. Handling is much easier...

with the z30 make sure you put the 450 main shaft collar on it so the motor doesn't come apart and dont look back :)

THAT is some good info. it's the answer i was looking for. i wrecked my E550 rappy, and i knew that motor worked well. i think the gaui motor will be shelved for now.

[michael88997]

lol yea just buy the spare parts bag for a couple of bucks and put it on as you would on the trex 450... meaning the part that goes again the bearing on the 450 will go again the bearing on the z30... locktight the grub screws and enjoy the POWER

I've got to agree - this is gold! Are you saying that the mast collar from a T450 has the same inside diameter as your motor shaft?

I have been having trouble with my Z20 can & shaft lifting up under load and pulling the pinion out of mesh with the gear. I had thought of trying to find some tubing to act as a spacere between the pinion & motor bearing but your idea sounds better.

Cheers

Good Idea - 550 motor shaft and 450 main shaft are both 5mm diameter

[concept1]

I went with the 1000kv scorpion because I had hoped to gain a little fight time over the RCP, but the scorpion had no guts at all, it bogged very easily, I did gain about 30 seconds of flight, but lost a ton on performance over the RCP. I then got the Neu which gives better performance and even better flight times but still doesn't have the power the RCP had, although I only have 4 flights so far, so I am still playing with gearing. 8s lipo it is unstopable though! But I really want a A123 setup. I like the way it flies with the weight of 8s A123, it is very solid in the air and I know 4-5 minutes are possible with good performance!

great info guys, just what I was hoping for!

[backwall]

Anyone have any log data showing motor performance during flight under different manuevers?
