Hello all,

After long waiting I'm finally completing my fist Logo 500, I've decided to go on an 8S setup.

My question is which batteries are good for this configuration?
I got some Turnigy 4000mAh 4S 30C Lipos on the way and I'm eyeballing the 8S Hyperion Split pack also, but we're in a debate with my buddy if it's too heavy or not for the Logo

Please let me know what you guys use!

Thanks in advance!

Fly it like you stole it!!!

The 8s Hyperion 4500 MAH G3's rock in a Logo 500 setup! You will get 5 minute flights and the packs can be charged at 5c. You can charge a pack in 20 minutes if you have a good enough charger. The Hyperion batteries are pretty light compared to other brands.

Team Sanjel!

I'm using 8s turnigy 20C on mine. No problem at all even if i use 1910H/1Y which is not the best choice for a 8s setup.

give to Turnigy a try for that price... And you have 30C. i'm also using 4000mah 12s on my L700 for a while now with no problems. I will try 40C when my current lipo will die.

Sounds good, now i'm releived

My setup is Jive 80HV with aScorpion 4025-890 so I was building it directly for an 8S setup

In this case I'll most likely get a Hyperion 8S also, I have the Hyperion duo charger, so chargin isn't really a problem

Thank you for your help!

How does it perform Benski?
How long your flights are?

I fly 3D so if I would get 4 min it would be awesome, but I might have to settle for 3:30 I dunno yet

You didn't say what motor you use?

FWIW I run a 55-10-32 + Tango 45-10 and after a LOT of head scratching

6S too many amps
8S too many volts = too high HS

I settled on 4S + 3S turnigy's and it flies great, they're cheap as chips and balance spot on.

Attach 2 chargers if you have them and done in no time.

Hope this helps

I did say the motor

"My setup is Jive 80HV with a Scorpion 4025-890 so I was building it directly for an 8S setup "

Currently I will run the 16T pinion since 15 is not available.

Also I was wondering what if I run it 10S or 12S???

Would it take it?

I flew nitros only for the past years I'm trying to get back into the electric game but way too many things changed here so I'm in the woods right now

i run 4025 890kv
8s 3800mah on 550mm mains.
the performance is very good,, flight time is 4 mins 3D useing 75% of the pac.

Head speed is 2350
from memory i think its got a 14T pinion fitted.
you can drop pinion size if you want lower headspeed.

Hey Bundain

It performs great. I'm currently still running the old 4025-1100kv (have a Kontronik pyro 600-09 on order). With the smallest mod7 pinion (12 tooth) I have to run the gov on the jive 80hv at 65% to get the headspeed at 2300rpm. With +12-12 pitch 7mins sports flying and 5mins 3d. Packs come down cold.

"Also I was wondering what if I run it 10S or 12S???"

I looked into this and yes it would take it, the only reason I didn't was because of charge logistics with my current charger.

10s - will need 4025-740 motor and 2x5s 3000 packs
12s - will need 4025-630 motor and 2x6s 2650 packs (or even a bit lower)

whatever battery config you go with you want the pack to come in somewhere between 800 and 900 grams.

You won't be able to run 10s or 12s with the 4025-890 because the kv is too high.

Thanks Ivor and Benski for the info
My head speed with the current gearing should be around 2400- 2500, might be a bit high but hey what is wrong with 2500 headspeed?

I tought that 10s or 12s not possible and a buddie of mine said the same, I just didn't understand why.

Turned out I was thinking that the main gear is 220T but in reality is 153T.

So all my calculations were way off and finally my buddie pointed out my mistake

I can't wait to fly it!

Fly it like you stole it!!!
