A mad brushless setup help

[Hayden]

Hi,
I was referred to this forum by www.rctech.net they thought some one could help me here with deciding on a brushless setup.
I have a good carbon fibre touring car and I need a brushless mortor and speed control for it I prefer lrp or novak because I can easily get them. I’m not to worried about the legality for racing but I wanted a setup to send this thing around 100mph or as fast as I can get it and a 4 cell lipo would be nice yes I know I’m mad but its fun.
Any suggestion would be greatly appreciated.

ya,theres not any sensored setup that i think can go that fast. I think you'll have to go for sensorless.

lehner 1930/5 and warrior 12020

I think it is going to be hard to reach on 4s lipo. Why not go for a 6s lipo? It would give you more potential. Put like a 1930 7t in it or 8t.

In this case is it better to go lower turns or higher number of turns?
It looks like I’m getting the 1930 but which one?
Is there any other ESC that will run the 1930 other than the worrier?

Type -project brushless bazooka- in the search engine of this forum and you might like the project.

No Novak or LRP motor will give 100mph. A 1930/5 or BASIC 4200XL would both be good options for 4s lipo. As coolhand said, 100mph is really pushing it on 4s lipo, especially for the lipo batts. 6s lipo might be a better option, and would put far less strain on the motor,controller and batts.

wow so much to think about I’m still studying these setups. so is it that sensored motors have smooth acceleration?. I was looking at the Lehner website and my eyes where drifting towards the bigger motors like Basic XL 5000 and bigger, will it work if I go huge to get maximum speed and control? I can use 2 3 cell packs or what ever to get it to run.
what about a phasor 15-3 (I can ge it cheap)its not meant for it but it can be modified.

That motor is a definate no-no. It can only do 20,000rpm, and the controller that goes with it is only rated for 30amps. The BASIC XL range of motors would be a good choice, 4200XL for 4s lipo and 5000XL for 3s lipo. Either would get you towards the 80mph mark in a good car

Sensored motors have sensors on them that tell the controller where the rotor is. This makes it so that power can be applied very rapidly. With sensorless, the controller detects the rotor position by EMF from the motor. At a low throttle input, it is much harder for the controller to detect where the rotor is, and can lead to "cogging".

If you go with a XL motor with a high kv (4200 or 5000), make sure to get some batteries and a controller that can handle a lot of amps. Those motors are more than capable of burning out some batteries that aren't up to the task.

Surely there is a brushless set up that can send a carbon fiber touring car around 100mph, I can gear it to most ratios to achieve these speeds if possible. I still don’t know what to get…..ok these are the brands I can get a good hold of: lrp, novak, nosram, and some others that are alot harder to get.
What about the nosram storm http://www.nosram.com/products.asp?id=30
It says it’s up to 8.4v so that means I can’t run it of say 22v??

[maxxdude1234]

That motor, or any other novak/lrp/nosram motor etc. will not do 100mph. You'll have to get a serious motor do achieve those kind of speeds. That nosram motor is only rated at 255Watts, I reckon you'll need around 1000Watts at least. Mike's got loads of motors that could easily achieve those speeds on this site, and he'll deliver to pretty much anywhere in the world.
I would say look at the BASIC XL motors. What turn motor depends on the voltage you plan to run.

[squeeforever]

actually, if you can afford it i think the lehner 1930 series would be better suited.

[Hayden]

How about the novak hv-maxx how fast approximately will that push my 1/10 touring car at 14.4v

[Serum]

That would be better. but what is wrong with the setups mike sells? a 9920 with a 9L is more powerfull than the HVmaxx and a few bucks more expensive.
