New Hacker Escs, motors & lipos

The idea of a Hacker 4 pole motor, and sensored at that, is rather awesome- that 1/5 scale prototype looks immense.

The escs though, they look suspiciously like rebadged Hoobywing XErun models as someone pointed out elsewhere.

The lipos are odd too- dual 4mm bullets will be a headache to work with, and the label on the packs says 90C, yet they are described as being 45C continuous & 90C burst; not liking the Maxamps style rating system...

The 1/8 motors looks like some other motor I have seen before.

Those ESC's look similar too the HW stuff, just nicely packaged. The hardcase lipo's look good, but dual bullet connectors? I wonder if Hacker is going to make a higher KV 4 pole motor.

Yeah, the dual balancer bullets seem a bit odd. Wonder how they are wired? They might be using MA-esque rating system, but at least there are no flame stickers!

The bullets are just for the power cables it seems- wired in parallel I'd guess- there is a seperate balancer socket on the hard case that balancer lead plugs into ( male connector each end I suppose ).

It's what I'd call a wanky setup... :lol:

OK, I think I see now. I initially missed the little square thingy (balance plug) on the end, and was thinking more along the lines of the old Trakpower hard-case packs with one center small bullet connection. The dual plugs are presumably paralleled to better handle the current the battery can deliver. Although, a simple move to 6/5mm Castle-like plugs would negate the need for paralleling, but whatever.

What makes you say that. :lol:

German engineering gave away to cheaper Chinese products for the car guys. Kind of sad, but it makes money sense :lol: to hacker. They didn't spend any $$$$$ on designing their own products and since they think Hacker is a high standard name, they'll probably charge people 2 times (maybe more) what others do.

Maybe they want to change their name to "Cheater" ? but Hacker is pretty similar tho...

Kind of sad what they're doing here imo. Their motors look OK though...

Well, I still got my high quality oldskool C50 and C40 Hacker motors :intello:

+1 here. I'll just wait for somebody to post pics of the internals. And the kv options are just sad.

Sad!

Hey if everyone adopts the rating system of using the peak value as the C rating then at least everyone will be on equal ground. Except for some of the more respectable manufacturers, the ratings being provided that are claimed to be continuous have really been the peak rating.

Its a bit deeper than that - what EXACTLY does peak current mean? Selling a pack with an individual cell's peak rating that isn't even defined is basically smoke an mirrors. If I buy a pack, I want to be able to ascertain the expected performance of the pack with reasonable consistency - I could care less if an individual cell can deliver 900 amps when the assembled pack can only output 100 amps due to construction limitations.

Not only that, but there is also ambiguity in what criteria they use when rating them. 30C? Sure, I'll buy that. But at what pack temperature? How much voltage drop? For how long before the pack is allowed to rest? At what duty cycle?

And for those who think IR might be a good indicator; be aware that the IR at 1C is different than at 10C, and again different at 50C. IR is not just a fixed resistance, but is a value comprised of actual cell conductor resistance (which is pretty constant) coupled with how much the chemical reaction can support higher discharge rates (which is not constant).

Aero-model has the pricing on the new Hacker stuff listed. I had a good laugh when I saw the pricing on some of the car stuff.

You weren't joking either- pretty much twice the price for the ESCs ( compared to the original hobbywing versions )- I'd just hope the customer service was mind bogglingly good/quick for that amount of profit margin...

My take on C ratings is that a burst rating means that a pack can handle a short burst to that amperage (ie for a 4000mah 50c pack that'd be 200 amps) without dropping under 3v/cell. Thats for a charged pack.

If it drops under 3v/cell under that burst, then the pack is overrated.

Thats how I view it anyway.

a millisecond burst, or a 10 second burst? It is all completely meaningless without an industry standard.
