Brushless Vendetta 100KMH :: 62MPH
 

A few days ago I bought a Duratrax Vendetta from a nice guy. I will get it in a few weeks. ( Needs to go from USA to Netherlands )
Anyway, I want it to let it go 100+ km/h, thats 62+ mph. With the stock gearing. There is already a Sidewinder ESC in the car and a brushless Align 430L 3550kv motor in it. ( http://www.hooobby.com/430l-brushles...cm-bl430l.html )
This brushless motor can go up to 14.8 volt, so a 4s LiPo. Do you guys think I will get the 100kmh/62mph with a 4s LiPo with stock gearing?
Or do I need to buy another motor? If so I would like to buy a 1100 series from NEU, which one do you think will be the best for this little car? :smile:

Thanks!

I realy think that the problem will be your drive train. The Vandetta drive train is all plastic gear, so if you put a Neu 11xx on 4s, i'am sure that your drive train will last for about 10':neutral:

I could buy a special brushless pinion, they also have a aluminium drive differential and I bet there are more hop-ups for the drive train.
So I think that wouldn't be the biggest problem...

No, it wouldn't. The biggest problem will be controlling the car at that speed. :wink:

It may be possible to run it at that speed but only if the space you run it is absolutely smooth and flat.

I run the same exact motor with a Quark 33 on 3s lipo in my Vendetta ST. The drivetrain holds up fine, but that was after I did a bit of shimming (I shimmed the internal differential gears that are pressed on to the outdrives). The outdrive gears have very shallow teeth, so it's easy to strip them if you accidentally spin out a few times. I simply placed very thin (.1mm) shims on the outdrives, then pressed the gears on to get the mesh ever so slightly tighter.

Drivetrain handles it just fine. I'm geared with a 15 tooth pinion and the stock spur; the car is probably only doing a modest 35-40mph, but it's a squirrely little bugger. I can't even imagine it at 60+!:lol:

This is what happens when you go too fast. Scroll about 3/4 through the page and click: Project Full Speed Ahead - street beat

Ok, so I wouldn't get the 62MPH with a 4S, and the Sidewinder can only handle 3S, so I have to change the gearing or buy another motor.
Which NEU motor would be good for 2S/3S, and I would get the 62MPH?

Thanks!

The Sidewinder should be able to handle 4s with an external BEC. Haven't tried it myself, but would like to some time.

I think linc ran a SW on 4s. I think he said it'll work if the setup doesn't pull too many amps.

I never said you wouldn't get 62 on 4s. I'm geared conservatively so that my motor will run all day without breaking a sweat (doesn't crack 140F on a hot summer day and no cooling holes in the body).

It's a bad idea to get a mini going that fast unless you have a good, high downforce body and a few wings placed in proper areas...:mdr:

Pretty extensive bl motor testing on the Vendetta ST - includes the Neu you are looking for -

Thanks to jaejw1.....

I put an 8500kv neu in my detta on 2s. I never took a speed reading but it was damn fast. I would guess 50-60mph, but I'm not sure.

Jaejw1 has a Neu too. His videos should be on the related videos on the side.

I was going to get another Neu or a Medusa to run on 4s but I lost interest in the scale. You can get steel diff gears and if you have steel cvds you're set. The plastic ball diffs held up fine for me.

A few days ago I finally got my Vendetta, with a sidewinder and Align 3550kv motor.. Yesterday I bought a Castle Creations CM-2080 so 8000KV. I will buy some 3S LiPs, and will look how fast it go..

I'm still searching a good body with many downforce, I thought about the body from a Robitronic Scalpel, the only problem is that the wheelbase from my vendetta is bigger..
So if somebody knows a good body, please tell me! :yes:

vendetta above 50km/h is very hard to control
I can get to 50km/h with my Neu 1105/2Y (5250kv) on 2S with 45/13 gearing

To get to 100km/h plus i would use 2S lipo, 45/19 gearing
one of the kamtec buggy bodies with high downforce wing
28-30mm wide foam tires to get as much traction a possible

since mamba8000 is a weak motor for vendetta and you need to use quite high gearing you would need to start rolling quite slowly

mamba8000 motor will burn on 3S doing speed runs

get Neu and Mamba Micro Pro

Dont burn your hand with that motor! Or the Chassis!

I would keep a VERY close eye on the electronics when you are doing speed runs. It will draw a ton of amps and your electronics will run red hot. I'm also worried about your lipo. the mamba motor will probably work for speed runs, but the vendetta is a heavy car. That is the reason most people use 28mm/400 sized motors like the ammo and Neu. Make sure to have adequate cooling. If you are using the 1/10th sidewinder, the esc will probably be ok.

I reccomend a Neu with the 1/10th sidewinder.

I haven't got a Mamba 8000 but a CM-2080, I don't know if there is a difference, but the only thing I can see that mine is expensiver than the mamba 8000..

Where can I find the Kamtec bodys? I only see a Mini-T body on their site..

Anyway, what about a MMM in the Vendetta? Wouldn't work, right?

CM-2080 is a 8000 mamba.

Mamba monster should work in the detta. You're runtimes will be slower due to the esc fan and just the size. You will need to put monster connecters on your motor or make an adapter.

MMM in a 1/16.... OVERKILL!!! :lol:

Why?

I don't want to buy another ESC, I also have a Velineon ESC, but the LiPo cutoff doesnt work for some reason.. And I'm converting a LST to Brushless, so I thought maybe the MMM would be good for the vendetta?

The only problem I can see is the size of that ESC.. :lol:

kamtec has ebay store just search for kamtec mako

I would use the vxl esc and just stop running when any power is lost.

You could also get an external lipo cutoff. I think Apogee has one called the Loud Obnoxious alarm.

I'm sorry, I didn't say it right.. The LiPo-cutoff doesn't work good even with a external LiPo Cutoff, and the Rustler with the Velineon ESC with a LiPo gives only the first 3-5 seconds full power, then the ESC automatically change to something, and the car is really slow.. ( I have to put the trigger back to neutral and if I give full power again the same happends )
I don't know what it is, but its very strange :whip:

Send the esc back to traxxas with $45.

45 dollar :no:

I'll try to repare it when i've got time... Anyway, a Mamba-25 or a MMM in the vendetta? :yipi:

mamba 25.

A mamba 25 wont get you anywhere close to the speeds you're looking for. You'll need a nice motor like a neu or medusa with a 1/10th esc. A mamba 25 could get you to probably 35 in the detta. Maybe 45 if you can disable the bec. you'll probably want a 4s setup to get to 62mph.

So first I will try what the speed will be with a Mamba-25 and the 8000kv motor :yes: (And I guess I won't get 62mph with stock gearing)

The next step will be a MMM and the 8000kv motor.. (Just to see the difference between the mamba-25 and MMM)

And the last step will be purchasing a NEU, and finally get 62mph :yipi:


@Metallover: This vendetta is yours I think? http://www.youtube.com/watch?v=S32YX...eature=related
Could you say me what motor is in it? On youtube it says: "Neu 1107/1.5D" but that motor doesn't exist?

EDIT: The only problem is a 3S LiPo.. I can't find a good one, that will fit.. :(

Thanks!

I saw this 3 cell LiPo: http://www.lrp.cc/de/produkte/vtec-a...-111v/details/

Do you guys think this is a good one for speedruns?

The motor is an 1107/1.5d that is 8500kv. I purchased it from a guy on here slightly used. I'm guessing Neu stopped making that motor or he got a special wind. If you are running 3-4s you can't use that motor.

If you are doing speed runs you have to improvise on battery fitting. A lot of people have custom chassis to fit everything. I think you can put one in the battery tray and one perpendicular to the first one above everything else. The mmm will make it more of a challenge...

Neu used to mass produce the 1107/1.5d. I got it from diversity models back when they were still in business, then sold it to metallover.

Byte, here's a good 3s lipo that will fit your vendetta with no mods. I've been using this with great results.

They are expensive compared to others, but are a perfect fit, and dish out loads of power.
