Brushless ?
 

Now then chaps.

Thinking of getting a brushless setup as I believe they can be run at the regionals / york and batley meetings.

Any thoughts, opinions or reccomendations ?
Any good tips where to get hold of one ?

Ta.

The new Novak looks good, and the LRP/Nosram/Reedy one looks good also.. I beleive these are the only systems that will be "legal" but i think also you can run the mtroniks at regionals...????

I like the look of that lrp/nosram/reedy system, since you can run proper motors on it when you have to.. Supposed to be pretty nippy also.

Does the Mtroniks come with a fire extinguisher? :P

As Jimmy said, I believe the Novak is supposed to be the dog's danglies.

You've got to much money you have Mr Shilli.....

Chris

just fitted the novak brushless to my bj4 will see how it goes on sat at york.

Blimey, I didnt know you had a computer bruce!

Welcome!

Might pop over, I like the york tracks usually and need to get this kyosho setup better.
Interested to see how the brushless goes also

Hey up Bruce.

I'm looking forward to seeing the BJ with the brushless setup, have you run it at all yet, is it as quick / nice to drive etc ?

Andy.

only had a run with it in the house seems ok hope i have got gearing right and ajusted the slipper seems better now see how it goes on sat.

Well.

For anyone that didn't see Bruces car at York on saturday, the only thing to say is FAST.

Bruce went past me so quickly, down the straight that the airflow from his car snapped my front shock tower... no kidding it was that fast, stupidly fast infact.

Brushless is The way forward. No doubt.

The new ones are fast even to fast some times =)
But i dont like the weight of the motor it is lump of lead
and i know it changes the balance alot and you have to
use harder set up in the rear.

Daniel, the LRP VECTOR Brushless motor is around 10gramms lighter than a 10turn brushed motor

Realy? Thats cool!
Well shame on me then :lol:

There was a rumur about a new BL system from LRP?

rumours fly around all the time, you can never know whats true or not.

there is always something new in the works, do you think they just release a product and then have a years holiday? :P

sounds almost like you know somet chris ! :)
the thing i'd like to see from these brushless beasts is smaller esc's, they all seem pretty huge at the moment ??
that wont stop me getting one though, when ive got the cash.

I actually don't know anything specific, but I do know that they work on stuff all the time.

the brushless speedo's are pretty monster, but thats the problem when you move the pole switching operations from the comm/brushes into the speedo... I am sure things will get better but there is so much more load on the speedo when running a brushless.

you can run the sphere with 2 Quantum worlds kit heatsinks on it instead of the sphere heatsink and that does lower its profile quite a bit

Chris!

Do you personaly think BL is the future?

After seeing Bruces run with the new Novak kit, I would say it has to be the way forward. I was so convinced i've ordered mine :)

Yes I do, who like rebuilding motors, with performance similar to brushed motors if allowed to, why would you run a brushed motor?

any idea if they will be allowed at nationals next year ? If so i would get one.. we can use them in the north east regionals which int bad, but it has to be the nationals before i get one.

Nope... not next year save your pennies for 2007!

(That's what I've heard anyway)

Definately not nationals,

but it is at regions descretion for regionals, also might be allowed for F2's, Juniors, F345's I think, check the minutes of the BRCA off-road AGM on the BRCA site

I've run the Novak twice now and compared it back to back with my best brushed motors. It's definatley faster (and that's the 6.5 motor). It seems to keep accelerating on the straight for longer, whereas you can feel the brushed motor reaches it's top speed and hasn't any more to give. I have a setup question though...

I want to set it up to give a smooth a power delivery as possible. To this end i've set the minumum drive at it's lowest setting, otherwise the power is too choppy at the low end. I can also set something called 'dead band' too, but I have no ideas what it is or what it does ? Can anyone give me a clue as to what it does an how I should set it so that I get the smoothest throttle response. Ta.

Andy

The deadband is the area around neutral where the throttle or brakes dont function. So if you have the dead band set to a high value, you will be able to move the stick (or pull the trigger) a little around the neutral mark with no response.

A lower value setting will give instant response when the stick (or trigger) is moved.

I recommend a low value for deadband, that way, you can drive smoother as you have control as soon as you move the stick. Having said that, with a high value deadband, you will automatically compensate for it after a few races, its all what you are used to.

Chris.

Thanks for the info.

Andy.

Just thought i'd update anyone with how the GTB is going in case they have one / are thinking of getting one.

It's on it's way back to Novak in the USA !

I e-mailed them with the overheating problems I had at the Super Cup and at York and basically was told there is a problem with the thermal sensor and the unit needed to be returned for repair / exchange. Bummer.

Cost a few quid to send it back, will post how I get on, so back to brushed motors for now, good job I didn't sell the lathe.

If anyone knows of any new brushless systems on the way, please post, I was considering jumping to the Nosram system, but my sensible side says I should wait.....

LRP Have a Sphere comp in the works, I was told that it was due out end of Jan but I have not seen one yet.

can handle a brushless motor down to 3.5 turns, and they also have a '4-star' motor due out with the speedo that is quicker than the all ready fast 3-start motor.

see mid-way down this page
http://www.rc10.com/shusting/CatalogHub/lrp/sphere.htm

edit - another bonus with the LRP setup is that if you region allows brushless motors, you will be able to use it, the Novak Velocity motor is not BRCA legal
http://www.brca.org/BRCA/elecboard/n...s%20latest.doc these are the only legal brushless motors for BRCA

I do know Tekin are working on a system, but as of yet, no details have been fed out, and even those in the loop for stuff don't know much if anything about it.

But it will be sensorless! :)

If you have a system that is designed to run as sensorless, then you can run both sensored and sensorless motors, whereas if your ESC is designed for sensored, you are stuck with sensored motors.

But with sensorless, your software got to be realy on the ball. (throttle mapping, shit like that).

I got my sphere comp and vector 4-star, not tried them yet, but some interesting things to note.

it comes with a 'power' cap pre-installed, it is not wired direcly to the solder tabs and some out the side with the FET lead and reciever plug, I thought this was a neat little trick, you can hide' the cap under the solder tabs as well so no extra floor space is used up.

it has a very cool looking blue LED on it :)

its auto sensing brushed and brushless operation, you don't need to switch profiles when switching motor types

its Li-Po safe, it has auto cut-off when you use Li-Po

vector brushless motor is 8500 KV, and 61200 rpm on 7.2v.... OMG!!!

needless to say... its going in my 2WD :D

Cool! is the motor a new one chris ?
What is the difference from the previous lrp brushless? will this one remain a bit cooler ? smoother ?

its just a lower turn brushless motor, more power basically, comparable to a 7turn brushed.

the speedo is a 'racing' version of their 'sport' sphere.

the sphere comp has no reverse and fully 'racing spec' in the same way the QC2 and QC3 are. it also has lower motor limits so it would run whatever is available now cooler and faster.

He guys,

This weekend i saw a new brushless system from GM/ graupner, its much smaller then the LRP/ NOvak system and it is also a lot cheaper.

http://shop.graupner.de/webuerp/servlet/AI?ARTN=2894

http://www.gm-racing.de/rwdownload/d..._brushless.pdf

It looks good, but the price doesn't come with a motor?

No it doesnt come with a motor, but i have seen the esc for like 129 euro (+/-86 pounds) and the motors are like 69 euro (+/-46 pounds).

currently at the 12th euros in gran canaria there appears to be very little difference between the brushed and brushless in terms of speed most using them have opted for the lrp/nosram system mainly due to size .

those running them compare them to a very smooth brushed motor the only advantage appears to be in runtime ideal for the throttle jammers but people are still dumping so isnt the perfect solution most of us were hoping for.

Most people still seem o be stripping the brushless down to clear out all the crap so maintainance is still required just not as labour intensive.

nice one Ian! good luck btw.

You 12th boys need to take something apart, the cars are so simple theres nothing else to do is there ? need something to pass the time ! :p

I think the advantage will come from the motor being the same run after run, not like a brushed motor. I don't think efficieny will be greatly improved.

Wouter, did you see the GM system running, and if so what was the performance like??

Any idea which motor was in use - GM currently have 2 "legal" motors i believe??

well all I can say is that the motor was a evo 2 but i dont know what wind or if it was a ifmar spec(sensored), (I didnt ask because my german sucks)

And it was fast, at least as fast as the competition i think. The guy
(kim sitensky)that drove the system was in my quali and i was driving a 10*2 and he had the same speed as me, he only drove better.

update from 12th euros

lots of people now reverting to brushed motors complaining of a lack of feel, responsiveness similar to that of massive turbo lag especially around 7 mins when batts have lost their punch
