6S 450 from HK
Tweet
I just noticed HK now has all the parts for 6S
Hobbyking YEP 45A (2~6S) SBEC Brushless Speed Controller
NTM Rotor Drive 450 Series 1700KV / 930W
Turnigy nano-tech 1300mAh 6S1P 35~70C Lipo Pack
However, Scorpion has two motors for 6S - 1630kv and 2010kv, and general feedback is that 2010kv is way better. So not sure why HK decided to make the 1700kv one. You would also need 15T pinion with this HK motor.

I believe even the plush can do 6s and is better than yep, right?

I feel Plush is more suited to airplanes.
YEP/Superbrain are more suited to helicopters. They also have governor.

Re: 6S 450 from HK
Super brain governor good? I dont know, So I switched to Castles for 2 helis. I have a 40A brain still lying in the package. May put it on a glider/heli someday.
Either way for my flying skills(loops and rolls) a flat curve is enough.

Re: 6S 450 from HK
I used SuperBrain 40A for around 6 months on governor mode, was pretty satisfied. It does not have Set RPM mode, only has Low and High governor. So its limited in feature compared to a Castle.
Later, me too upgraded to castle

Re: 6S 450 from HK
Looks like that motor has a burst watts of 930 = 22.2V X 42. The max constant current = 30 Amps. If we consider it to be 25 to be on the safer side(considering its already 6s for its sizr). Its wasst would be 22.2 X 25 = 550 Watts approx. The same that I may reach If I use a 4S system on 2836 3700 KV motor(
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8137
). What say?
EDIT: I have this motor on a funjet ultra on a 4.5 X 4.5 prop 80 plush and 3s 45 C nanotech 2200mah and consumees approx 550 watts. I can only think of this motor performing on a 4S.

Re: 6S 450 from HK
With the above setup, for you be in safe RPM range (~3000), you will have to use a 10T pinion. Not sure if 10T is available - lowest I have seen is 11T. For 4s, most users use 2500-2900 kv motors.
Still, don't think 4s can be compared to 6s. 6s will be a much better machine because of the higher voltage and lower current draw. They would also be easier on the batteries.

Re: 6S 450 from HK
I believe I have the 9, 10 T _ had ordered them exactly for this setup from experiance RC or somewhere else a year ago, dont remember. Am looking at 9T would give 3000 RPM at 14.8 V(If govened on castle) and 10 T would give 3300. I may go for 10 T. The quality of the HK Pro series should hold up that RPM. Anyway the tail and power train would be align. Incl the TT and the gears.
Did u notice a comment on that motor, Its the same as another 3400 RPM motor, just wired differently. I hope they have atleast increase the guage/turns whichever is necessary.
All Iam worried about is the motor. Hope it wont give up. Its an expensive setup. People have used it on funjets on 4S. Hope it will survive.
And since the motor wont bogg down much on 3S itself. Am assuming on for 4S and same HS, the bogging should be much much lower.

Re: 6S 450 from HK
OK, here is the reason why Iam more exited than a 6S setup. Let me make it clear.
1) Point one.
A 6S setup = 1700 RPM X 22.2 V = 37740 Motor RPM.
My 4S Setup = 3700 RPM X 14.8 V = 54760 Motor RPM.
Lets Consider that they both are really powerful. For the 4S setup. I know the motor myself.
2)Point two.
I had done this experiment 1.5 to 2 years back so I dont remember the values exactly.
I had benched a motor(not the above) on 11 T. It showed 2900 HS at 20 AMPs or so. Now at -10 pitch it showed 2500 RPM at 26.x AMPS.
Now the same setup at 12 T pinion had reached 31++ RPM at 0 degrees(throttle curve reduced here to avoid head explosion) and at -10 degree the setup was consuming 30 AMPs and HS dropped to 23XX at 100 throttle.
Notice the difference?
Smaller the pinion, better the Headspeed at extreme pitches and lower power consumption. Hence lets assume, 960 watts means just higher T pinion gobbling up power at extrememe pitches.
Now lets go to the example above in point 1. Look at the RPM ranges. Now both the motor can maintian what ever HS required at 0 degrees. Now which one would bogg down at extreme pitches and recover back quickly? Lets not worry about who consumes how much current.
Got the point? Me running the 4S setup is equilent to running that 6S motor at 8s and reducing the pinion! However if u run that 6S motor at 8S u would burn it. But this 3S motor on 4S wouldnt. >
As I said its all theory bro. Let see how it goes

Do you have a watt meter and a tacho?

Re: 6S 450 from HK
Am I reading the graph right? Its just 5 Amps? The entire setup flew on an average of 115 Watts? (23V X 5A)? I tot u needed > 180 watts just to stay in the air.
By the way the governing looks gooood.

Re: 6S 450 from HK
Your battery can deliver 45 Amps at 35C and you are barely consuming 5 amps. Thats good again. Waiting to see spikes

Re: 6S 450 from HK
You are right - something is wrong
I just did a bench test at 0 pitch, and the amp meter showed 7.75 A at 3000 RPM. So that is 180Watts at bench.
For 3100 RPM, it was ~8.8A
So, looks like my controller is not reading correctly.

Re: 6S 450 from HK
Boss, I was planning on copying your governor settings, why have u set the gain at only 7 when the min recommeded in 15? I have set it to 20 is it fine?
Here is the graph attached. The motor 3900 KV and gear 10 T pinion. Governer set at 2.8k, 3k and 3.2k. But when I just run the motor w/o the gear it shows 3250 RPM. Why the 50 RPM more? IS it because there is no load?
Motor reaches 48000 RPM at 3200 HS.

Re: 6S 450 from HK
I am still experimenting with various gain values and trying to find the optimal value.
Many recommend to start with 15 and adjust accordingly. I too agree with this idea.
I feel, the default 25 is bad for small helis. What i noticed is, if the gain is set high, whenever there is a big drop in the headspeed, it will very quickly try to correct it. This quick headspeed correction causes a tail kick and almost guaranteed crash.
Try 10-15-20 and see if you can notice any difference. I am also doing the same
Regarding the data logging, not really sure why it shows 3250. May be the no load thing.
Why there is no current reading on your graph?
The powerout reading also provides good info. In governor mode, it should not be hitting 100 frequently.

Re: 6S 450 from HK
Hi Raja, How are the Lipos holding up? have they puffed? I have decided to let go of the 4S project(way too much stress on the motor) and planning to jump into the 6s wagon. deciding between the scorp 2010 vs 450MX 1700 KV. There is barely any direct comparision on the net, except for the fact that 450 MX is just 1/3 the price of the scorp 2010.

Re: 6S 450 from HK
Hi Vinay,
I have completed 110 flights on the NTM 1700Kv motor. It holds up pretty good. Excellent VFM at $18. I have slant gears. Head speed governed at 3250 RPM.
Use lower Kv scorpion motor if you are using slant gears. Use the higher Kv one, if you have straight gears.
I have a recent batch of Nano tech 1300mAH. I have completed 20 cycles on them - no puffing till now. I get 5 mins of sports flying at just 55% of the battery.
The earlier batch puffed and lost power within a month or two.
I have improved my skills w.r.t taking care of lipos. I do not charge them over-nite now. I charge them before going to the field. I consume only 55% of the battery. These two methods improve battery life.
