Pro Motors? Patrick?
 

Got a question for Patrick or anyone can speculate.

I am just wondering that since CC will be coming out with the neu designed purpose built motor for the Monster, is there any chance that similar motors will be made for 1/10th scale? It would be nice to have a higher quality motor to pair with the MM that is a neu design without the neu price.

I know that in the end the medusa's seem like they fit the bill, but I was wondering what CC's plans are, if any.

If they do it will have to be rebuildable and have logo stamped on endbell, it will have to be Y wind and 2 pole, as well as solder posts over wires coming out the can. This is for roar legality, RC Pro is open to all brushless, no matter the setup

I really hope they do make a ROAR legal brushless motor. Maybe that is why they list the Y series of 1512 and 1515 motors? Thinking of the future with there Neus for a possible brushless 1/8 class?

ive never really understood the difference (except for the terms) but why does it matter(i.e. roar could have legalised both y and d motors...)
sorry for the stupid question.

because roar does more to hold the hobby back than help it progress.

Thankfully, most people out there don't race in roar sanctioned classes if they even race at all. Most of the hobby is made up of bashers anyway. I could care less if the motors are roar compliant or not. Most of what I run or am interested in running is not roar compliant.

the lipo issue is relivant, but banning senosrless and the like seems as if novak paid them well...

I can't blame them, can you imagine trying to drive a powerful sensorless setup? With the improvements in lipo that are coming, a really powerful car could be built. But racing is usually trying to get the cars similar, so that driver skill is what is competing, not who has the most powerful car.

true. but you DO (proven fact) go faster with a less powerful car that can be controlled rather than some stupidly high powered setup that spends most of its time outside the fastest line. ill leave it at this, dont care for a big thread in the wrong thread!

This is true, only so much power can be handled by the current crop of electric on road cars. Imagine if 1/8 scale electric on road became popular! I can easily see some big power systems, and expansive tracks too. Current 10th cars are only good for a certain size track and that is what the current selection of roar legal stuff caters to.

theres one that was built in brisbane and the vid on youtube makes it look slow. its scary fast and if it hit someone, expect at least a week in hospital. I was talking to one of the guys in the vid who was mashalling and he reconed that if such a class existed he would refuse to marshal, just becuase u cant hear them coming... and for draining 3 high capacity lipos in less than 6 minutes... well... i can think of more fun things to do with the hr or so waiting for them to recharge!

Not sure what you're referring to - but Roar has not banned sensorless systems. Sensorless motors and controllers are completely roar legal assuming they fall in to their other restrictions (rotor diameter, solder points, company name stamped on endbell, and most of all, rebuildable).

I'd be surprised if they came out with any "pro" 1/10th motors unless you considered castle-style neu 1509/1506 motors to fit that category. Though, who knows.

Yeah, because after 10,000 hours of running, I'm going to need some new bearings. :na:

haha. Go brushless. Still, though... If you're serving your motor any kind of justice it's bound to get a little dirty once in a while. It''s nice to be able to flush any grime and extra oil away.

does anyone know how much this castle neu is going to be?

Around the same price as the current Neu's. The motors coming out from Tekno/Neu are the same price

So would it be possible to buy the CC/Neu can and use it on Neu motors?
Was anything special done to the motors in covering the cooling holes?

The ones by tekno are still hand built by neu in their factory, the castle ones are a neu design but being mass produced in china at CC's factory. This is per patrick. I would expect the CC version to be 125-150

The 1st motor being built is the 1515 and would expect that to be around the 180 mark?

I would think it would be less than $180, because the ESC is going for ~$170~ about, and the combo is supposed to be selling for about $300 (street price).

Yeah, didn't think of that. The MM and CM36 is $10ish more if you don't buy them in the package

Theres also something about the "proper" neu motors having a carbon stator, and the mass produced ones wont have. I think it was the stator, it was some familiar sounding component anyway :) And yes, there will be no big open holes like the current neus designed for aero use.

wrong, for example Tekin motor are rebuildable, with solde tabs and engraved endbell, they still failed ROAR approval why ?
They are delta wound,

ROAR legal motor must be Y wound motor, which is obviously more difficult to drive sensorless :/ ...

Your thinking of the rotor. :yes:

Why is Y obviously more difficult to drive sensorless?

You guys want to know a strange thing and why I don't like ROAR at all. The Trinity N60 and N40 are both Feigaos 380C and they seem to be Delta wound and they both are approved by ROAR. ROAR to me is like the FIA, but ROAR board seems to be getting their hands wet $$$$$$$ if you kow what I mean.

No, that just can't be true, I just don't believe it, I mean that would never happen........ :whistle:

It always seems like Bob Novak can make things happen with roar though. :rules:

Kind of like some have them :whip: and some don't.

Thats quite a claim, If its true, thats a heck of a conspiracy towards other brushless manufacturers. Because its in the rules that Y winds are the only ones legal.

I just checked the roar rules and trinity, the only brushless motors trinity is saying are legal are the duo 10.5 and 17.5 motors

Look at the bottom and it says they are ROAR legal http://www.superiorhobbies.com/istar...&id=TRI0201!SH.

I opened my Feigao 380C http://www.rc-monster.com/proddetail...AO_380C&cat=20 and my Trinity N60 and they look the same. You guys be the judge. I can't find my camera and once I do I'll show you guys the inside of both.

Rotor is probably too big and MOST of the redline motors are probably delta wound (since most, but not all, are whole turns and do not have "half turns"). There's a few things that need to be met.

This is why I don't race... Too much politics and BS.:whistle:

You can't always tell if a motor is wye or delta by looking at the inside. The lehner 19xx series for example can be switched from wye to delta only by resoldering a few connections on the rear endbell. You don't need to alter the coils.

Yes and that's a plus for Lehner, but the minus is the price and that takes the 19xx out of it. It would be awesome to see a 19xx competing with the weak 200-300 watts motors. Man Lehner is missing a big share of the market if one stops to think about it.

Which "weak" motors are you referring to? Brushed?

The current crop of sensored motors. They spin fast, but could never make the power of even a Lehner 1920.

Lutach, the Novak motors (lower turn ones mainly) are nearing 1 hp in power output. I think the 3.5R puts out about 620 watts according to the Novak motor chart. From the 6.5R and down, they're all putting out more than 300 watts if decent battery is being used. You're right though, their motors spin pretty fast (10k Kv is freaky).

To be fair....Lehner is...err....well, they're Lehners.:mdr:

Just imagine if they could do over 1400 watts like the 1920. That would be awesome. I'm going to have someone modify my HV4.5 to a lower turn motor and wrap the magnet with Kevlar or Carbon Fiber. I'm planning on making a speed record for 2S lipos. Should be fun.

1400 watts would be unncessary, and therefore, JUST barely enough to have fun....:mdr:

Make the HV motor a 1.5 turn, and see if you can source a bigger diameter rotor. HEHEHE!

A Lehner 1920-3 would be my choice for crazy fast power. I already found a few sources for a bigger rotor, but I don't know how good they'll be. Plus they want me do send them a detailed drawing with dimensions for the rotor. I can't do anything like that though. I might get the 5mm conversion and send that as well to get a wrapping treatment.

The 3.5r went nearly 80 mph on 2s at the fastest rc-car challenge. Novak actually answered why a wider rotor isn't better. They said that the bigger the rotor, the smaller the airgap between the stator and the magnet, which causes the iron core to become oversaturated, thus producing more heat and lower efficiency. In other words, you would need a bigger stator in the novak hv motors for a wider rotor to be affective.

Oh... They need a bigger stator and then a bigger rotor then....:mdr:

That's good. Then I don't have to actually draw anything :lol:. Does anyone know what the strength on Novak's magnets? The rotor might have space to have it wrapped with Kevlar. That should be good to hold the magnet together under extreme RPMs. A new 2S record shaw be set :yipi:.
