I believe its the 8S first the 12S needed a touch more tinkering IIRC.

!!!

Not on the official site yet...cannot wait!

GETTING EXCITED!!!

but is it still the case that the 8s controller will on work with 8s if using mechanical brakes?

and

6s with motor brakes?

And the 12s controller only can take 12s if you use mech brakes

and 10s if you use motor brakes?

The 8s controller will work with 8s and brakes... The 12s controller with 10s with motor brake, 12 s with mechanical brakes.

12s is available now, the air version.

Thanks Patrick...

I most definitely will be wanting to run 9s on the 1520.
Due to my savage now being more of a fatty since i have added the GH Alloy Bulks and put the lipo boxes back on... i have had to gear the top end down a bit to keep the truck from getting hot. So i now need to run more voltage to get my desired speeds... so i will definitely be wanting to run 9s.

Patrick, i know that these neu motors are well made, and i have heard people running 10s on a neu 1520! obviously this exceeds the reccomended RPM.
I used a calculator and have the figures here assuming the following.

Neu 1520 (1600 kv)
Motor Resistance = 0.008
Current draw = roughly 120 amps?

Voltage Vs Rpm
Voltage---@3.7V-------@ 4.2V
8s--------45,824-------52,224
9s--------51,774-------58,994
10s-------57,664-------65,664

If i can i would ideally like to run 10s and gear my top end down to compensate.
I have heard of few people running their motors on the limit like this with no problems.
Do you think this would be ok to run? obviously i would expext premature motor failure...

What do you think?
Your advice is more appreciated
Thanks

Josh

What is your rtr weight? Why don't you think that 8s will be enough for you (I can tell you from experience that 8s gives lots of power).

[Jahay]

im not sure... but it used to be 14.3lbs fully loaded with 6s worth of lipos

Now it has GH Alloy bulks, Nylon Roll Cage, lipo boxes... so i would say around 15.5-16lbs? maybe more? i will weigh it properly very soon.

Oh i know 8s will give me MORE than enough power... But i want to go all out with this setup. I have spent a lot of money thus far and i think i should just max it out and be happy. Otherwise after i buy the 8s controller i will want the 12s one anyway! we all know how it is in this hobby :)

also considering...

i know many that run the 2650kv on 6s... on 6s at 3.7V its at 58,830 and 4.2V at 66,780

also i heard somewhere that, these motors are fine for higher RPMs but the bearings are only rated to 60,000rpm...
What would a bearing failure do to the motor? Would it be repairable or do you usually want to catch bearing failure before it happens? Can i replace the bearings with some decent ceramic bearings that are rated to higher rpms?

[brian015]

For my 19lb truck, I didn't see any real advantage to 10s over 8s, so I'm sticking with 8s. I can gear it for 50mph and with good batteries it has almost uncontrollable acceleration.

[SV6000]

Just because you put 10s on the your truck does not mean that the motor will do that RPM. The rated RPM is "unloaded" so the load that is placed on the motor by your gearing means that it will not rev out as high

[nuz69]

The neu motors Kv is given at max efficiency, reached when the motor is loaded.
When I ran a Kv test with my NEU/CC 2200Kv motor unloaded I found 2500Kv, so I wouldn't try the NEU/CC 1520 on 10S anyway. I think 8S is more than enough with this motor ^^

[Jahay]

hmmm ok 9s it is haahaha
thanks for all the input...

but still want to hear from patrick :)

I know we've all seen these pics in the other thread, but what caught my eye was the comment in the article: "The ESC is actually available now, the motor and conversion kit will be hitting in about 2 weeks."

So what's the deal? Anyone seen these available? Or did I miss something in a different thread?

[Jahay]

i know!!! But i havent seen it available anywhere!

More importantly, when is he 12s version out?

[Jahay]

everyone knows the air version is availble... this thread is regarding the car/truck version.
