I am trying the 1000kv because I am running 8SA123, this I hope should really work well, if I can get 5 or more minutes of hard flight I will really be excited!

Wow! 14mins on 3300mAh, this is great!
Can I know your flying style?
I also recently dropped my HS to about 1800 and got 12mins of gentle flying and used 2650 mah out of a 3300 pack.
I posted a graph on one of the threads I'm just not sure where it is...might be this one...

I got my Scorpion 1000kv and hooked it up but still waiting on a tail slider. I hate mail ordering parts.... ugh! Ordered broken parts and missed a part that needs replacement. I hope it comes tomorrow so I can see what kind of power and time I can get from it.
BTW the motor is itsy bitsy!!! I hope it can fly this heli. :confused:

got my 1000kv also, and yes it is TINY!!!
FIRST flight was kind of a dissapointment, on 6s lipo it does not cut it with my gearing, a real dog. But on 8s A123 it flies real good, which is what i WANTED it does not have the power the RCP H/18 does but I do get a easy 5 minutes out of it and has good power. If it were regeared it probably could fly nicely on 6s lipo, but my goal was to gain flight time on 8s A123 and still have good 3D performance. motor does stay cooler then the RCP. I plan on getting some more flights on it today and will report back Monday. with the Rcp on 6s lipo I could run a flat 100% cure and get very good performance and on 8s A123 85% and on both packs I got 4.5 minutes max. with the Scorpion 6s lipo at 100% is almost unflyable, it flies but can not do any 3D, rolls are sloppy, but 8s A123 is very good and I get a easy 5 minutes probalby 5.5.

I tried as well getting 2150 rpm on the ground with 13t pinion all else stock. This motor runs hot!!! cant keep my fingers on it, much hotter than my Z30. It does have more power than the z20, but I havent check flight time yet, was just hovering and getting rpms. This is all with RCPV2 blades.
This is where I want to be 2000-2150 rpm, not all insane 3D, just mild aerobatics.

I have similar results : 14min flight (gentle flying) is a bit to much for my 3300 pack (overpass 90% discharge).
I reduced to 13 min flight and get about 2900 mA used (do not remember exactly...).

Vic, the z20 should give you that.

So we all know....what gearing are you using on your heli?
So far no raving reviews on the Scorpion. :DOH
If you have a Z20 please compare to that.....is it worth going to Scorpion over the Z20.
How about a Z30? would that be better than the Scorpion?
So far...results are dissapointing, but maybe it's gearing, etc.
Please keep posting as you get more time on the motor...
Thanks

Gearing and curves really are the key. Those adjustments make such a huge difference in every motor/battery combo I've tried so far. There seems to be a power "zone" where certain setups work great, and fine tuning that "zone" or "band" (which can be broad or narrow) does improve both times and performance, ..but finding it is a pita. :)
For example, I ran the z20A with the 16T for 3 packs back to back and the performance dropped way off on the 3rd pack. The reason was heat! It worked well for one or two flights, but after that, decay big time. The ESC, batteries, and motor were too hot. So, I moved back to the 15T and ran 6 packs in mild 3-D that way and things were much cooler so i'll stick to that for now. Just a 15% boost in torque/power would be sweet though ;) The 14T setup with the z20 just doesn't have enough punch for me doing most basic aerobatics.

I flew my 1000kv some more on Sunday, Sat night my 19t one way finnaly let go so I installed the 20t which gave a few more RPM and now on 6s lipo with my current gearing (geared for 8s 123) it does not bogg at all, and it does fly ok, head speed is still down at 100% but this is not likely to be a power house motor! but it is stone cold after flights! and my lipo's are also just barely warm. it has no were near the power my RCP h/18 1000kv does with this same gearing, I am running revco gearing with 21t pinion which is about the same as 13t stock. so upping the pinion would help. BUT, i get max 5 minutes of hard flying on my evo 2500 25c packs, so upping the pinion would probalby give more power but reduce time.. now on 8s A123 it flies very well, i get a strong 5 minutes of flight but packs are gone at 5 1/2 so i set my timmer for 4:40 and prepare to land shortly after the buzzer. with my RCP my timmer was set at 4:20 so i do gain 30 sec to 1 minute of flight (hard flight) and performance is only down slightly. I can not at this time recomend this motor except for 8s A123 guys! although it is better then the stock motor and would give the option to move to 8s A123 and good performance later on. Over all i would say this motor meets my true expectations, although I had hoped for more! I gained flight time with just a slight drop in performance. performance is exceptable. I will try uping the pinion this week but we are do for rain the next 5 days!

In your opinion, would the 1210kV motor be a better choice for 6S lipo?
Actually, I have the upgrade motor, 1100kV/1500W, working pretty well right now. Since I realized I had a short boom, I went from 550 blades to 500s. I'm geared 20/68 w/ the 20T OWB and I'm getting ~2300 rpm at 75% throttle, 0* pitch. Seems like I have plenty of power.
I wonder how the Scorpion 1210kV motor would compare.

I think the 1210 motor or the 1400 will be the Choice motor for 6s, several guys got them last week so I am curious to hear their results this week. I spent many hrs finding the sweet spot on the RCP h/18 and it really flies very well even though most guys don't like it. Once geared properly it does not overheat and has lots of power, I really want to go 100% A123 cells so I tried the 1000kv, I might also try a 1210 just for kicks after I try some different gearing on the 1000. again one note this Scorpion is very tiny compaired to the stock and RCP.

With the Scorp 1000kv I am getting 2400 rpm on the ground with 8sA123, 14T pinion, 42T, 61T,20 OWB, basically stock gearing. The motor was hot, but ambient temp was 98 degrees that day.
I droped it down to 2250 on the ground with 13T pinion. Its around 2100 with 6s lipos. Today I will test fly at the field instead of just hovering.
The Scorp 1000kv will generate more HS than Z20, but will see how much torque it can handle with some noob 3D.

I take it the RCP h18 is the upgrade motor? Probably what I have on my 550.
Switching to the 500mm blades, putting on the lightweight paddles and turning up the cyclic transformed my 550 into a whole new machine. Went from being super stable to a hot rod. I have a little bogging on punch-outs, but I think that is a combination still using woodies and having the throttle response set at medium. I think I will change throttle response to high and try that. I'll probably get 500mm CF blades and switch the ESC to governor mode soon.
Last night I flew a 3 minute flight with some mild 3D and only put 980mAh back in the batts. I'm using FP 3200 Evo 30s. Thinking of getting another set of batts soon.

what flight time did you get on the 14t, and how hard did you fly it? I have the revco gearing 21t, which is similiar to the 13t stock. and my motor was barely warm after 3 consecutive hard flights. you can easily hold the motor in your hand for as long as you want! I did not have my temp gun with me though. my RCP would have been warmer you could still hold the RCP but it was much warmer.

I flew again today Scorp 1000kv, but the weather was 102F so it still ran hot. I got 5:30 for max time doing 'Noob 3D' with 8sA123s. I set my timing to normal and it was much better than the low timing and I am getting 2280 HS at hover not bad considering I am only using 13T pinion. The motor will bog with fast continious tic tocs in similar fasion as the Z20 however it has a bit more power. I didn't get a chance to run any lipos because it just got too hot at the field. I will try a 15t with 50t front bearing and that should give me even lower head speed but more flight time. It appears that 6+ minutes of flight is possible with 8sA123 and 1000kv Scorp motor. You look at this motor and you think it will not fly this heli because of its size, believe me it has a lot of punch. If you gear it right you can easily get 2400-2500 hs.

Due to the high temp wires and magnets they use, just getting hot shouldn't be a problem. I also have had the Scorp 1000 for a few weeks now and it gets hotter after I shut it down to change batteries than it does running. I'm using a 50 tooth front gear with a 16 tooth pinion at 95% and it's pretty responsive.

My Scorpion's shaft doesn't have the notch in it like the RCP for the set screw on the pinion. Is it OK to use this way, or should I grind down a flat spot?
Thanks,
Jason

I ground a flat spot on mine

Jason, I just tightened mine really good with loc-tite, if it loosens up I will put a notch on it.
Helibrick. Good to know the motor runs typically hot and I am not doing anything wrong! My trex 500 motor also runs hot and I was told its normal. Also what head speed are you getting with 16t and 50t gears?

I test flew with lipos for 9 minutes set at 90 percent flat throttle and put back 2975 ma back in the 3300 6s pack. Mild aerobatics and ff flights. These numbers seems to be equivalent to my z20 motor with a 14t pinion. If you need more power than a z20 use a 14t with the Scorp, don't know how it would do with 15t pinion but I bet it will be nice for 3D
