Motor	KV\V	9.9	13.2	16.5
6XL	2,779	27512.1	36682.8	45853.5
7XL	2,382	23581.8	31442.4	39303
8XL	2,084	20631.6	27508.8	34386

Nominal Voltage		3.3

That was me in excel as I already have the figures up and I am interested in running 4s A123 on one of the motors as well.

You will most likely be best off with the 7l on 5sa123. Make sure that you run a 5s2p setup, 2 packs of 5s in parallel, as the 7xl can draw some juice, and a single 5s pack will drop alot of voltae trying to keep up.

what does 3-5s mean? Is this the range you will be running, or you don't know yet?

The 6xl would run far too hot on anything, even the 7xl gets too hot... the 8 or 9xl would be perfect. IMO

yeah the 3-5 is my range.thanks

[zeropointbug]

So is it 3, 4, and 5s packs that you will have? Or you will be purchasing a 3, 4, or a 5s pack for this setup?

Sorry for not understanding...

yes 3-4-5 and i will be purchasing.

would those axles hold up to brushless

I've looked at those many times and wondered the same thing. They are for the original emaxx, not a 3.3spec or the newer 3906 model, but assuming you have an older emaxx, there is no reason why they wont holdup. They look like better made versions of the RC4WD punishershafts, only for an Emaxx.

I would personally get the 3.3 shafts instead.
