Logo 10 battery question
I'm buying a logo 10 with a Neu 1512/2.5D motor, a CC HV 45 Speed controler and a 17 tooth or 18 tooth pin gear(comes with both). My question is this....can I use a 5 cell 1p 18.5 volt 4000 mah lipo with this setup and about what can I expect for flight times doing just normal ff ? The reason I ask is because I already have 2 of these batterys. If these will not work can someone recomend a good batttery setup...please keep in mind that my charger will only charge up to 5 cells.

Thanks.

If it doesn't fit force it.....If it breaks then it needed to be replaced anyway !!!

I run one more cell than you, 2900 mah batteries.
Hover uses about 400Watts.
I'n not familiar with your motor. You could use the pinion calculator
at fxaeromodels to see if you'll be in the ballpark.
The other thing would be if the Neu is efficient at that RPM.
I'd try it if I had that setup.

Puttzing around I get 7-9 minutes on E-moli's. You should have
a weight advantage over mine with lipo's

Do Not run that setup with a 17 or 18T pinion
That motor with a 17T pinion on 5S will put your headspeed at just over 3000 rpm's!
You can go down to the 13T on 5S, you will still be looking at about 2400rpm but you should be able to dial that down a bit with your radio. I cant comment on flight times and as long as the packs can handle the amp draw (80 amp bursts) you should be able to get decent power. Note that you are way below the max rpm of that motor so your loosing a lot of torque, that is a 2042KV motor rated at 60K rpms, you will be pushing about 37K unloaded.
If the brain was simple to understand, we would all be too simple to understand it.
