Power systems discussion

They both have great power the 6s 1600kv machine flys lighter than the 5s 1900kv machine due to the battery weight.They only fly different because of the weight. I still can't say which one I like better have to get more flight's in on them.

I'm currently running stock esc and motor on 13T using 6s EVO 2170 and a 6s Evolite 2500. I'm interested in seeing more 6s reports on the Scorpion motors, trying real hard to resist the urge to order something. I would really like to get this 500 screaming power setup like my 600. I first flew it with MAH baldes and was less than impressed, the sounds at high pitch or fast rolls makes me thing they are not very efficient. Waiting on new Align blades any day now then may try the 14T for fun.

Checking the Scorpion webpage I see they have a new Scorpion HK3026-1000KV (12n8p) listed. My thinking to go with this motor would be the sub 200g weight (If it's not a typo) On 8s (2x4s) Evolite 2100 packs, batt weight would be 370-380g, and you could run a CC45HV ESC (59g) I would run the 16 or 15T pinion.

Could be an ultimate light weight setup with similar flight time to a 6s 2500 setup (based on available watts from the packs, could be longer based on weight savings)

May just have to try it out when the motor is available.

The title says it all. I have tried the 1900kv on 5S, 1400kv on 6s but the 1210 on 8S is it. My setup is Jazz 55, Scorpion 1210, 2 Flightpower Lites 2100mah 4S. These packs fit in the stock location just like the 6S pack. There is no modifications needed to get the canopy to fit. These packs weigh only 185g each. Here is the data I recorded.

[skeppley]

Looks like a powerhouse joe.
Did you get any data with the Scorpion 1400 motor and 6S?
If not, mine will be coming this week, so I'll do a compare of that and the stock align motor.
I'm hoping for a noticeable gain thats not to hard on the packs.

[smokenjoe50]

Just to warn you guys. Jazz 55 + scorpion 1400kv +8S = SMOKE! I smoked 2 new Jazz 55 ESC's within 20 seconds on spool up with the 1400kv. I have no Idea why. I know a guy using a CCHV45 with no problems.

Has anyone tested the Medusa MR-036-050-1600?

Has anyone tested the Medusa MR-036-050-1600?

Trextuning did test flights with that motor: Video (http://www.trextuning.com/blog/?page_id=184) and short blurb/summary (http://www.trextuning.com/blog/?p=185). From their posting, it doesn't seem to offer anything more than the stock motor.

No wonder it didn't have the power they are using 6s 4200 packs, thats got to be a heavy setup!

[Socal500]

For you pilots that are sport and mild 3D this back is really nice. $130 for 8 plus of sport and 7:30 of sport/3D mix. Im mild 3D so I cannot say how this pack would work for hard 3D. These times are with 16T so if your just sport you could drop down to 15T and extend your time even more.

I lowered my tray to be flush with the bottom edge of the strap slot in the frame. This gave great clearance and canopy fit and also balances perfect with a full size servo on the tail like the 8900. If you go with the smaller tail servo you could just move your ESC to the side mount position. Mine is mounted under the tray.

Whoa, you're hammering that puppy. Good stuff! Looks like you got the setup. What pinion are you using?

BTW, regarding the batteries, weigh them. I think you'll find them to be more like 200g each...manufacturer stretches it a bit. I know I'm splitting hairs but makes them look better than competative packs. They are good packs though.

[Super D]

Hey All!! Has anyone tried the Hacker Brushless A40 10S 8 Pole? This seems like a kickass motor for the 500 and seems to have just about the same specs as the scorpion motor everyone loves so far. any thoughts?

[smokenjoe50]

I am running a 14T pinion.

[Super D]

your running a 14tooth on what?

[BobOD]

Scorpion 1210 on 8s

What about flight power 30c 6s 3200mah packs more power and longer flight times than the 2500mah 25c packs

[Socal500]

113 grams heavier also. I know when I was flying the 2500 6S and switched to the 5S 4000, which is only 85 grams heavier than the 2500, I could really feel the weight. Im not referring to power either just the characteristics of aerobtics.

[Finless]

Yep that is why I like my 2500 Evolites over my 2500 25C pack. You can feel it and I prefer a lighter heli myself. It just feels crisper.

I just finished my TRex 500 and am still waiting on the EVOs to arive. I have some TP Extreme 4s 3850s laying around from a HDX500 and they fly pretty good. Slight bogging but nothing I would complain about.

I tried a 19 and 20 tooth and prefer the feel of the 20. I am getting 5:30 flight times at 100%. It's sweet. If it flies this well on 4 I can only imagine what will happen on 6s.

I did do some tight funnels with the 4s and the same funnel with 2 align 3s 2100s and the tail blew out on the 2100s. So the TP Extremes are actually better than paralleled aligns...I was shocked. I actually thought I was going see something amazing with 6s but the exact opposite occured. Anyway, here is a photo of my exact battery placement, as you can see it fits perfectly. I love this bird!

[PlasticHead]

I've seen posted that the 500 on 4S wouldn't be good for anything but mild FFF but I saw the video posted here http://www.helifreak.com/showthread.php?t=52626 of Charley Stephens flying a 1750 gram HDX500 on 4S and hammering it around pretty well. Seems like a valid alternative if you have quality 4S packs. The reason I bring this up is I'm somewhat invested in FP EVO 3300 4S packs for my 55" 3D planes (using those packs in a 1200 watt system with my 3.9lb Extra is ballistic), and I am invested in 2100 packs which seem to offer limited flight time and uses twp packs per flight while hoping the packs are equally matched, buying 5S 3300 packs like JK flies is getting close to T600 battery costs which I find unreasonable.

Thanks for any observations

Tried TP3850 Extreme 4S over the weekend started with 19T not bad, then changed to 20T. I liked the 20T. Performance wise is not too far away from the 6S setup ( 2 packs of TP2200 Extreme 3S). CG remained no change well balanced with either the 4S or the 6S config. Based on the 4S and 6S experiences, I believe JKs 5S with TP3300 SXV probably is the bset for all. I am really happy for Align, the Rex 500 is highly recommended for all current and future heli pilots, it is a great all around machine, very well made with no single issues after 20+ flights. In addition, the quality of the motor is great so far. However I am using Schulze 32.55K controller which sit right under the battery tray.

[booger]

my setup
scorpion 3026-1210
13 tooth pinion
2 4cell 2100 evolite in series
CC HV45 esc
performance was good
I am not a 3d pilot
batts come down barely warm, motor hardly any heat detectable, esc nice and cool as well.
5 min 30 second flight time

[watso]

so will two 3s 2500 evolites in series and 13tooth pinion give good results?

[Rototerrier]

I believe the unanymouse cry in all the forums on power discussions is:

6s = The Best
5s = Good
4s = Tolarable for Sport

2 3s - Depends, but will never match the power and performance of a 6s.

When I first started test flying and only had 4s packs I decided to try 2 align 3s packs. They were tolarable and no better than my 4s packs. They also puffed. They were the old aligns...no big shock there.

After my 3s and 4s experience I decided to buy just 1 6s EVO 2500 (25C) and it was awsome. I then purchased and tried the Align 6s 2500 to see if saving money would render the same performance. Yes, it did. I then orderes 2 more aligns, but due to stock issues at ReadyHeli I was forced to get 1 Align and 1 EVO. Sooo, I now have 2 Aligns and 2 EVOs and they all 4 rocks.

I have a log book where I mark every single charge. I always run them down to around 3.8-3.9V and always charge them at 2C. I set my timer for 6 minutes and that seems to be the magic number. It will fly for 7.5 but that is pushing it way down.

Anyway, in a couple months I will have some long term real life data to contribute to the forums on the Align v EVO discussion. Hopefully my Aligns can keep up, because they feel the same if not better and are way cheaper.

Hi I have a T rex 500 that I can barely get off the ground only once with the new batteries(2200 18C) could I get it to eye level, now it only goes no more than 1 foot off the ground??
Is it a battery problem or what?

[silverado777]

My T Rex 500 barely goes off ground with 11.1V 2200 18 C what's my problem
