Mamba 8000 comp x
 

I'm pretty sure that I'm getting this for X mas, what pinion would work well and what lipo should I use. I'm looking for speed and reliability.
Thanks guys.

For what truck? the Wraith is a nice motor too, i had the 8K, the wraith is throwing out a lot more torque

My bad, my little rc18t. so you like the wraith better? This will be from my significant other, and i try not to explain too much as she gets confused worse than me. Maybe later I will try the Wraith motor. Question stills stands, thanks:027: Serum! LOL

UUUUUMMMMMM no comment...lol.....troy get confused...never...lol

Go wriath, go wriath..

Laugh now, cry later! I can't wait til you go LIPO and you call me! LOL:005: :005:

LOL..

Looks like you shouldn't exchanged phone numbers...

Hehe, he pays the price more than I! LOL
Seriously though serum, what would you suggest for a pinion and batt?
Thanks

Erh, well...

I only used the 8K with the stock sized tires and the 55t spur with the smallest pinion that comes with the rc18t..

Here she is on 6 GP 1100 cells..

After 1 run, the rear tires are slicks..

Very cool Serum. Is the 55 stock too? I definately want lipo in mine though and will do upgrades as things go to hell because I'm not sure of what all will need.

I am running the 6800 in my rc18T with 13/55 gearing and 6 cell battery and everthing stays cool, no fans or heat sinks. 55t spur is the stock gear for the 18T and the smallest pinion gear that comes with them are 12t.

Thanks Tazz! I got the 8000. But I heard the 6800 is better? I'm not gonna do much off road with this little thing, it's going to be a street rig, do you think I'll be fine? I want to run 3s lipo? stock gearing?

That is odd. Mine came with 60/10. I wonder if they changed this at some point in time for a particular reason.
Anyway, I just bought a 9200kv Dynamite C4/Quark 33a/3s LiPo for mine. I will be using this gearing at first (66/10), then if everything is in check, I will upgrade to a 12t then a 14 that I also have and see what happens with that. Unfortunatelly I have everything except the Quark, it won't be in till the 22nd of December according to my LHS. I'll keep you posted.

You going to get a video to johnny.
Was isabel on the camera rene?

Yeah, that's Isabel! not shown though, only audible.. :p

Ciao,
this will sound a little bit crazy, I know, but I run a mini-t with a mamba 25
controller, an external BEC, the mamba 8k motor and lipo 4S.
By now I'm using it with normal timing and a 16 pinion with 60 spur.
What can I say .... It' a ROCKET.
I cannot say with precision because I do not have any instruments to measure
the speed, but I think it can reach 130 km/h quite easily.
And I was very very surprised to see the motor was not so hot as I thought .

Sure, I am just able to make up and down on the street, without any turns,
and it's quite difficult to make it running straight on, even if it's longer about
5 cm and it has a Gyro on the steering servo.

Ciao !

So the mamba came, I'm having issues with where to put the rx and the esc? Anyone got some pics I can check out?

Thats the carziest Mini-T ive ever seen!!! Basically a Mini-t dragster. Really cool. Like it alot.

What do you mean by a gyro on the servo? Where did you get the chassis?



This is the way I did mine. I put them back to back on top. Its only way I could make it fit. Having the esc that close to the rx is probably not ideal, but I havent had any issues so far. Here are a few pictures so you can see what I mean.

BTW: I have the mamba 8K also. Total waste IMO if you run lipo. Its way to fast you cant control it. I have 3s and 2s packs for it, but I run it on a 6 cell nimh packs just to make it semi reasonable.

very nice t man, what about an rc18t though? LOL
My second question is: Can I run 3s lipo on the 8000?

Oops... DUH.... Don't know why I thought you were talking about a mini-t. Must have been danverz post about is mini-t that threw me. I blame him.... Yea, Yea... Thats it...:005:

Sorry.:dft001: Ive done that a few times lately. I gotta start paying more attention.

jhautz: Don't forget to put that dogbone back into the cup before you take it out again! :dft012:

It actually has a broken outdrive cup right now. Last time I ran it I used 3s lipo and it just split the outdrive.:019: I have the new one, but I haven't gotten around to replacing it yet. Like I said.... 8K is usless on 3s.:p



NewE: Sorry. I'm no help for a rc18....

can you run 3s on the 8000?

It gets hot, but it hasn't blown up on me or anything.

yet....:013:

Here is a quote directly from the CC website under ''How fast does it go?'' section. Since they quote a speed with 3s, I would assume you can use 3s.

''Competition X Package: 8000 Kv
With the stock gearing and a 3cell lipo pack, one of our Mini-T's has been confirmed at over 60mph.
With a 2 cell lipo pack, or 8 cells = 48mph
6 cells = 32mph
Basically, this motor is almost unusable for actual racing, unless you've got a really big oval track, or will ONLY use 6 cells or less! Also - drive train parts at these speeds most likely will have a reduced lifespan - stock up on diff sets!''

Looks like it has got a reason to split up on you! is that a GPM aluminum output cup?

Yea. They were crap. Split on the first run. I should have known better. Anyway. The stockers are going back on when i finally get around to it. Its been sitting that way for a couple months now. Just never seem to find the time for the minis anymore.

3s should be no problem neweuser. My brother runs a 4s on your same setup on his 18mt and same with danverz as mentioned above. My brother however has only run it a few times so no telling how long that would last.
If you are using the stock chassis, please post some pics of it when you get it finnished so I can see how I'm going to do mine once my controller comes in.
Thanks

Yes we can call it a little drag-T :)
The gyro is an helicopter element, it's useful to compensate the rotor torque
by the tail rotor. It just "listen to any turn energy" and it try to compensate it.
The chassis is self made, from a 2mm silver cabon fiber.

Yes sure ... I have to say my goal was to make something really really fast.
My next step on the mini-t will be a 540 plettenberg shadow motor, a mamba maxx
controller. and some lipo 2S. I made some calculation and I think it will be able
to go over 150 km/h with a 42 pinion .... really do not know how I will be able to
make it fit, anyway it sounds cool for me :)

The mamba 8k with lipo 4S is sooooo fast. unbelievable.
I bet I'll be able to use it no more than 10 times. haha :)

Glad to see you like it.

Ciao,
Daniele

Sure, and without any problems.
You maybe will have some, if you go over 3S.

With a 3S pack you will push the mamba over 100.000 rpm.
With a 4S pack you will push it over 134.000 rpm.

I say: the controller is all right if you go for an external BEC ....
I think the motor is over its bearings capabilities ...with 4S but not with 3S.

So yes, you can use a 3S without problem with the 8k.

Just keep the temperature in mind, while you are trying different pinions.

Ciao,
Daniele

It's not much, but it's my start.

I beleave that the 60T spur gear is stock for the 18MT, because of the larger tires. 55T for the 18T and 18B. But I could be wrong. There are also 2 spur gear covers for under the chassis, one is labeled T for the 55T spur and MT for the 60T spur.
3s with the 8k motor should be fine especially if you will only be running on pavement.
I have mine setup with the rx in fron in the motor and the esc on top of the chassis brace.

That is how I have mine set up too. Works great! Just need a Lipo now and I'm set. I also think I need to re program to a softer brake...:027:

Well, some things i see you replacing right now are dogbones, arms, shocktowers and shocks. You should have gone with the FT version so you have some upgrades already:)

Interesting. Mine is defineately an 18T not 18MT.

I have 3 racing shocks right now. Except the front as i broke one and went cheapo's with gpm's i had laying here. I have ti bones right now, but won't get those in until i break something!
