5s Combo

[ethinger]

do u guys find the piro rate of the heli slow?
am finding it very slow, and am using bigger tail blades (ep8 tail blades)

[mudbogger2]

do u guys find the piro rate of the heli slow?

nope. I even turned mine down a little. Even with the stock blades.

[Grant H]

do u guys find the piro rate of the heli slow?

Yeah. Its kinda slow with the stock tail blades. Havent tried anything else yet..

[mudbogger2]

Well the 5S 3700 EVO packs fit like a glove.

Battery sits almost completely inside the frames now and balances perfect right where it sits.

[Kövi]

We have made some records on 5S.

The used config was the follow:

Hacker A30-10XL ( 19T, 1:4,94 )
Kontronik Jazz 55-10-32
Medusa 6V/2A BEC
Polyquest 5S/3700
3*Multiplex Polo 4 Digi
GY401/9650

Pitch range: +-10,5deg
RPM: 2700

We fly soft 3D. The Lepton was extremly powerfull and precise. The tail was really weak, but I will replace the tail blades. The overall performance is amaizing. The landing gear and fins are wery poor also.
So I will make new ones to replace them.

And finally here is the DPR graph:

Mind sharing with us where you got that pinion?

[mudbogger2]

Think I may have a 5S motor here. Hope to test it out tomorrow on stock gearing.

Lot of the airplane guys around here running these motors have nothing but good stuff to say about them. Also Atlantahobby is a first rate store.
Big e- plane shop but the owner is super nice and very helpful( wish all stores were like this).

Looks good JON,ill be heading that way,let us no how you get on!!

thanks for info.

I tested this motor today on 5S.

http://www.atlantahobby.com/shopexd.asp?id=5973


Outside temps were 96F and high humidity. Rain cut the testing short today.

Using the 24 tooth pinion I got:

85% throttle @ 2650 rpm
95% throttle @2800 rpm
100% throttle @ 2880 rpm

Performance was decent but not as good as the 4S setups. Temps were 163f after a few 3-4 minute flights. I had the align esc set for mid timing and mild throttle response.

I am going to bump up the timing and throttle response to see if I get a performance increase and see what the tepms will be.

At this point I would say this would be a good choice for someone who already has 5S packs looking for mild 3d performance (maybe better once I change the timimg).

[Finless]

Modbogger, yes on low KV motors set the Align ESC for high timing. I did this and it dropped the temps a little on my Hyperion. I tried all the throttle response settings and to tell ya the truth I could not notice any difference but I run high anyway.

The 19T pinonion was premade by a small machinery and finalized by me.
This is made of good quality brass and not aluminium.
It works perfektly in our Leptons.

Shutup :arggg: :arggg: :arggg: Just kidding. Must be nice to be able to get diffrent pinions. You could make money selling those right now.

How about if you get a few of the 19 t pinions made and I am more than positive you will sell a good amount of them just here on helifreak.
Heck I will take one right now if you have any available. :mrgreen:

[Finless]

I will take one myself! How about $20 for one!

I received my 19 T pinion today and I am able to run 85% on governer mode and the heli dosen't sound like it is going to fall apart. My tach died so I don't know exactly what the rpm's are but it sounds like I am in the 3000 range. I had a few flights and I was able to touch the motor without burning my finger. I am running the Evo 20 5S 3700 with the Hacker A30-8XL with the CC HV 45 and this is ballistic. This is the right pinion for this combo as far as I can tell(only 2 flights) and I am loving it. :twisted: :twisted: :twisted: :glasses2:
Thanks Istvan.

[alexsand17]

Where did you get the 19T pinion?

Alex

[eheliflyer]

Where did you get the 19T pinion?

Alex

Kövi was kind enough to send me one. It is the brass pinion that he was talking about in the eariler posts.

[Finless]

Yea, I just got my 19T pinion from Kövi as well! I plan to try 5S as soon as my 12T motor gets here!

THANKS Kövi!!!!!

Bob

[alexsand17]

Kövi if you have any extra left could you sell me one.

Thank

I spooled up my A30-12XL on 5S 3700 flightpower NF packs with the 24 tooth pinion today. 70% headspeed is 2975 rpm on the head and power is VERY good. Temps were withing reason and this is without a fan installed.
Got a fan coming for it. I am going to run it this weekend and see what king of data I can get with the FDR.


I did run this motor on 4S and it was well just ok. Tail was letting go(where it has never done that before) some and headspeed was 2600 at 95% throttle.

I will say this I do not wish to ever fly below 2800rpm for 3D.
I am not telling everyone to go run near 3000 rpm but it really kicks arse above 2800.

[Finless]

YEP! I am running 2900 myself.
I am owrried about the blades at this head speed but it is really going well so far.. I put in 5 flights last Sunday and no hint of a tial let go and I was doing so backwards inverted stuff :)

Jon, you still thinking your 12T is a 10T?
For some reason I cannot get a hyperion 12T now it is back ordered and has been for 3 weeks! Makes me wonder? Not sure i want to ry 5S on my 10T with the pinion Lovi sent me?

Bob

[mudbogger2]

I really do think my 12T is really a 10T. that is why I am asking for some data from other users. may help clear that up.

In the meantime this 12XL is really looking good.

[buster1]

Bob, are you still running the same setup? Or have you changed the pinion for higher headspeeds,
I am also running your same setup - would curious if you changed, how has the performance changed, and flight times with batteries, motor temp., etc.

[Finless]

Right now I am still running the same setup power wise.
I plan to try 5S soon since I have a 19T pinion now.

Bob

[buster1]

great, I look forward to your results - if good, maybe I will give it a try,
Are you looking for some more torque and longer flight times?

Thanks,
Jeff
