mambamax out of stock what to buy ?
 

Hi !

I,ve ordered a rustler xl_5 with:
steel outputs,alu-idler gear and rpm bearing carriers+ballbearings:004:

And i'd like to buy a mambamax 5700kv motor for it but hey seems to be out of stock everyvere !! so i'd like to know if the feigao 370c 6L or 6s wpoud be a good motor for my rustler ? and which controller ?

I would go for the Feigao 380C 6L and a Quark 125 or either the Mamba Maxx ESC.

Woud that setup be faster than a novak gtb 6.5 ? or the quark pro125+feigo 8 or 6s ?will the 380c 6L pull wheelies in the rustler on 6st nimh cells ?and is 45mph topspeed be possible ?

Not sure on top speed. It would pull wheelies no problem. A Quark 80 would do. Thats what I meant in the first place :p. It will definately be faster than a GTB 6.5.

The stock brush motor is a 12T 550 motor and traxxas clames that the new rustlers will go like 35mph. will the feigo 380c 6L on a 6cell gp3300mah nimhpack be a lot faster and give mor runtime than the stock motor ?

oh and are the quark 80 esc's prewired ?

To get their 35mph, you have to run a 7 cell and the bigger pinion that comes with the truck. So it doesn't do 35 on 6 cells, and it probably is overgeared for general running with the "35mph" setup.

The 12T 550 motor sounds pretty cool for a stock setup... it's different and I don't think anyone really knows yet how it runs. I'm guessing it runs pretty strong but sucks some battery too.

But no doubt... the 380c6L should give better runtimes and better performance overall.

You will pretty much get better runtimes with almost any sensorless BL motor since there far more efficient.

it'll be faster!!! trust me! I really don't think the traxxas speed gauge is right. the Jato imo, does not do 60 mph!

Actually newEuser, that is acurate. It's in the new RC Car Action.

woud a feigo 6s and a quark 80 be a mor powerfull setup than the 380c 6L with the same esc ?

Probably not.

If I were you I would wait for the Mamba Max system. It will be worth the wait to have no thermals and great ugradable software. It can also handle more than six cells.

...And just when will that be?

3 weeks the backorder is.

The Quark is just of a good ESC, just finding a good motor I would say.:002:

The 380C 6L will likely push a Rusty somewhere around the 33-35mph range. I've got the 6L in my T3 and have GPS'ed it at 33.5mph on 6- GP3300's. It would also pull wheelies pretty easily when I took it onto the grass.

I too think it would be worth it to wait for the Mamba Max.

The Quark may be similarly good, but there's nothing like computer programming and being able to update the ESC's software on the computer instead of sending the ESC in to be upgraded. To be honest, I haven't even programmed my Mamba Max using the throttle stick yet, it's all been done using a computer.

Anybody know when Castle is supposed to send out the next batch of Mamba's? I know the site says 3 weeks but its said 3 weeks for a while now.

I don't know when that will be, all that I'm saying is that I would wait. Two years ago they said it was "coming soon". So I'll say more will be out "real soon". :dft012:

Hi !

I've ordered a mamba max 5700 combo :004: for my new rustler xl-5 but i'm not shure about what gering i coud be runnin on 6cells ? can i go with the stock gearin? for the 12T 550 brush motor that comes with the new rustlers ?

You can try the stock gearing, but it would help to get a set of pinions, like this one:

That way you can play around with the gearing to find the spot where the temperature of everything will be optimal.

Which battery pack will you be using? If it's anything short of GP3300 cells, you aren't going to get as much performance as the system is capable of providing. The battery feeds the system, and the motor can only put out as much power as the battery gives it.

yes i have gp3300mah packs :018: how much runtime do you think i'l get ?
i,m gonna order one 2s 8000mah maxamps pack and one 3s 6000mah or maby i'l start with some 4k 8cell pack's :004:

I'd read around before getting 4k batteries. rcgroups is a good place.

Since you plan to use a 5700 kv motor, that is gonna suck some current. If you go with Lipo, make sure the continuous current is high enough.

The maxamps 600mah cells can take 60amp's continius and 72 for 10sec and the 8000mah 96cont and 128/10sec both of these packs coud be enough right ?

I use the Maxamps 2s 6000mah pack with the 5700, and no problems. The pack hasn't gotten above 105 deg. F yet.

how long runtimes do you get metalman ?

I'm not sure, as I've never run for a full battery at once. I would estimate about 20mins, though.

that sound's very nice ! how fast does your car go with the mambamax5700 motor on 2s ?

I would estimate 35-40. It's definitely fast enough for the local track. The current setup has a very large jump on it, and most other cars/trucks were only getting to the landing or a few feet in front of it, I cleared the jump past the whole landing area, about 6 feet from the landing ramp. That was just normal track running... and then I managed to smack into a wall.

^^^^^

was that with a rusty ? and have you tried to run your truck on 3s lipos ?woud it make it over the 60mph line ?:027:

does this sytem heat up alot after eath run or doe it stay kind of cool ?

That's in a Dark Impact with 2s Lipo. The chassis has very limited space for mounting batteries, the 2s pack fits perfectly, and I don't feel like dishing out $120 for a 3s 3200mah 20C pack (Kokam cells).

The system never gets above about 155 deg. F. I do have a fan over the motor, simply because the Dark Impact's design doesn't allow for any cooling air over the motor.

Do you have to turn the car over to put the batteries in? I saw a picture where the bottom came off for your batteries.

Yeah, it's bottom loading for the batteries. It's actually nice to have that, since I don't need to take the body off to change the battery.

Anybody know when Castle is sending out the next bath of speed controls? I emailed them and they said:
I'm not allowed to answer that. You would have to ask the distributor.
We cannot give out confidential information like that.
So I called Tower and asked them and they said they didnt have a set date and it was an uknown arrival.

WTF? I didn't realize that would be considered confidential!?!?

I doubt it is confidential but maybe they don't set the dates, the distributers do?

Although you can order directly from their site, so no idea!

Tower changed to stratus to order pending, I hope this means they are closer to getting them in stock.
