LRP 1/8 brushless stuff!!
 

LRP S8BX Brushless

Looks like LRP is getting into the 1/8 brushless game too.

For some reason that site doesn't work for me. Please post some pics.

Here you go Lutach:

Those batteries look like 4S (maybe 2S2P?) lipo, are my eyes paying games on me?

Looks sensored...

Defiantly sensored, blah! but also looks like 4s, 2s bats in series, looks like theres bullet connectors on both sides of the batts?

ESC looks nice and small. Makes it easier to fit in, but I wonder about how much power it can take. Everything LRP makes now is sensored so it makes sense that they would offer a sensored setup in 1/8 too. Like Novak. Doesnt look like anything very innovative though.

Look! They didn't even shrinkwrap the angled bullet connector!
(Look in the circle)

That's some funny stuff. Well here is what they did. They made a motor similar to the Novak HV so now I know who makes the LRP motors then they just got a bit smarter and noticed their ESC can work with 4S lipos lol. It's the same ESC they offer now, the the sensored only ESC might offer problems in 1/8 scale racing if the sensor plug comes out.

It will probably be quite pricey as well...just look at their 1/10 scale controller.

Yes it will probably be as the new LRP Competition ESC is $240. One can get the Monster combo from Mike for just a few bucks more.

waste of time there LRP. Although their 1/10 8.5t BL motor does perform rather well...

Lol, this is going to be interesting to say the least. Even if it is a brand new ESC, LRP's other brushless units are incredibly unreliable...they're always frying from overcurrent, or for no apparent reason (within spec). That already doesn't bode well for this thing, IMO.

But if this is their new SPX or one of their Sphere models with a few tweaks, then it's going to be - in my opinion - hopeless. I can't see that sensored 1/8th is going to last anyway, but if they can't make a reliable 1/10th ESC, then I dread to think how this is going to fare under the greater stresses of 1/8th. They'll probably charge through the nose for it, too.

I might well be wrong, but that's how I see it.

Looks like they moved the weight towards the rear as well(dumb). Good for me. :)

First thing most of these companies need to start doing is providing real AMP numbers. I can't see the LRP ESC providing 400A per Phase like they state on the Spec or Comp. ESC. I would actually love to see some one try to pump out 700A+ with the Ko ESC. I remember when a respected drag racer went to the LHS to get the LRP Spec and saying it would provide 400A per phase. I told him if he wanted to try my 200A and he said the LRP puts out 400A. Funny how the next time I saw him, he wanted to return the LRP. I asked him again and the fool said he was having his own ESC being made and as of yet, I haven't seen nothing, but he did ask me for a 200A through one of the forums lol. My guess is that most of the companies put out the over rated specs to get all the fools to buy their products, because they go by their numbers. Now the only way to get the companies to actually stop doing that is to be more educated and start asking them how in the hell can I get 400 or more amps from your ESC? Maybe they'll feel the pressure and start posting some realistic numbers and start education a lot of people out there in the hobby.

They will be playing catch up Mike. You RC8 kit even puts the AE Electric version to shame. Your product is awesome Mike.

LRP Sphere ESC in a 1/8?

Agreed. Novak even says their GTB a 540A ESC, but in fact we can tell is just a good 90A speedo.
To find this number, I had to take it apart to see what MOSFET is used inside, then search and read the MOSFETs' datasheets from International Rectifier, ST semi, and On semi. But I can imagine not everyone will do this, they have to believe what the advertisement says, no second choice.
On the other hand, I can't say Novak is lying, nor LRP, because the MOSFET datasheet does mentioned somewhere for that number of amperage, but it's pulsed spec under extremly strict test condition such as the temperature inside the silicon die no more than 25C, which is obviously not realistic under normal use.

I think its great that lrp is making a sensored system. I really like the lrp comp in 10th scale and the only reason I dont still run it is because I switched to the tekin this season. Lrp is my backup now. Either way the next 8th scale I do will be sensored or atleast sensored at startup like the tekin.

I just found some more info and pics:

I don't like their buggy, i think there is too much weight in the back of the car. The motor looks also very small, i think a Feigao L can will outpeform it easily.

But it's a really huge improvement compared to the Nuremberg Toy Fair 2008 where the were proudly showing their 1700mah NiCd packs :rofl:

You mean you don't like their conversion of this buggy :whistle: :yes:. Mike mentioned his mount for the LRP/SH buggy keeps the weight further forward, unlike LRP's.

That's what i wanted to say :angel:

The LRP stuff is all made by Speed Passion (so Hobbywing). Their motors are Feigaos too. If anyone wanted this, they could probably pay 2/3 the amount for the Speed Passion ESC and motor. Not that you'd want to.

If anyone has picture(s) of the inside, I can see who actually made it. At the moment, I doubt that Hobbywing made it since the LRP doesn't have many of its features.

Speed Passion certainly make the LRP 1/10 ESCs and motors... In the same way their engines are made by SH. Basically, like so many things, it appears that for the extra money, you are getting a badge/name...

Trust me on this one, Speed Passion is not a manufacturer. LRP has been out for a long time and even before Speed Passion was ever created. When I say things in this nature, I only bring actual facts.

+1, trust in the Lutach baby. :yes:

I stand corrected. (Though their engines are definately made by SH)

I actually read somewhere that when AE was testing their new E conversions for their RC8s that they used a slightly modified Sphere Comp... That is probably it... Just disabled BEC probably... Haha

Yeah SP has nothing to do with LRP

If any of you guys actually raced you would know this will be worth it. I run 10th touring car, 10th 4wd mod buggy, and 10th mod truck. I run LRP in my cars, I have the new KO/Orion esc in my 4wd buggy, sphere in my truck, and a new 2.0 LPF waiting to be used. All are good escs, sensored wont die any time soon. Its to perfect for racing IMO

Im on the other side of the fence from most guys here, why I dont post much over here. Im a full on race dude, and same with my cars and gear. I know a few here race, but not many

just curious if you have ran a sensorless brushless system? you seem pretty sold on the sensored option. my guess is you run roar events and 1/10 is pretty much a sensored deal with them. I like to race as much as i can and have used both systems, sensored is a LITTLE smoother for me but if it means using a crappy 2 pole novak style motor, count me out. since i have been racing at my local track at least six people have ditched the novak hv system for a castle one. not trying to pick on your post just curious what sold you on sensored for 1/8 scale racing? and as far as it being good just because its LRP, the proof is in the pudding!

Ive been here longer then you have, and probably into the BL deal longer...

went from the BK and fegaio, NEU, CC, Tekin ETC. Been there, done that. Like I said im a 100% racer, no bashing. I bought the R1PRO to run for 10.5 TC when it came out and it sucked horribly, when your pushing your car hard in the A it just didnt have the smooth no hiccup powerband you need. Why do you think all the tip top guys run sensored, and not sensorless? Tekin came out with the R1PRO and it was a flop, no racers liked it, and they came out with the RSpro. LRP is all sensored, Orion, KO, even hacker has sensored stuff. Tekins new 8th motors are sensored

Novak sensored stuff is junk, especially there ESC, so if thats what gave you a opinion you havent ran a real sensored system IMHO..... you are right, I have NOT ran sensored 8th scale, might be the stupidest thing ever, but with ROAR rules, 4s seems like the standard you could say, im not happy with that, id rather run 6s, lower KV bla bla. The novak HV isnt what im talking about, im talking about 10th scale stuff,

Tekins system seems like the best running deal, 6s sensored racing. IDK whats to go wrong on that one? And dont take this as a flame war or anything, just my opinions as far as RACING. NOT for the most of people into rc who bash

Yep, another company relying on uneducated noobs to keep them afloat... :whip:

"Ive been here longer then you have, and probably into the BL deal longer..."

Uhhhh ok.... no comment.

all i was trying to get across is tenth scale, is tenth scale, 3-5 lbs 7.5 volts. 1/8 scale is 6-12 lbs 14.8+ volts, two different worlds. i dont think it will work better in 1/8 just because it's the norm in 1/10 racing. just seems like a bias opinion for someone who doesnt run 1/8 scale?

Why do you think all the tip top guys run sensored, and not sensorless?

usually its their sponsors that dictate that:) not to mention the only LEAGAL
sytems are sensored.....
ive tried both (novak, lrp, castle, tekin, mgm) in 1/10 4w mod over the last 4 years racing when i can and the gtb/5.5 always worked best for me.

i guess the only way to find out is for you to run my rc8 with both on 6s and let the laptimes tell all.

I run nitro 8th scale with my buddy. I think 8th scale will work better sensored, how much IDK. Just IMO

Hows about you come out to Lakeport, or NorCal and race, or we can meet up at cap city to do some practicing since they dont race anymore? 8th around here isnt the greatest, but if you have somewhere to run, I can bring the nitro crew over and do some work? But id be happy to show you how my wheeler, and the rest of the cars run. I personally dont have a BL 8th buggy, but have plenty of buddies that do, especially at NorCal, im not Bias, believe me id much rather run HV, and go that way, but for now ROAR isnt doing it

Sorry, but I just dont see people running touring car and swapping to sensorless at this time Im not saying that sensorless 8th scale is bad, its a hell of a lot better then the 10th stuff for racing, but at the same time on dirt traction isnt 99% like onroad is, so maybe... But I will try out the RC8 if you wish =D those are nice buggies! Especially with the wide rear tower

I'm starting to feel like a drama hound.. Admittedly, I love to read the start of a nice flaming session!

I can see some good points to both side though, and not to deter from the issue of LRP bringing a quality product to the market. It seems more like a bit of function or concept debate in my opinion.

I have put my $$ on 6s sensorless systems. ESC's from Lutach, MMM and Sentilion are all working reliably. On the track, I have had problems with the center diff unloading all the "spunk" to the front and not getting good traction until I ease off and try again more gently. I've played around with the MMM settings to get the acceleration curves I wanted, which helps a lot.

With a comparable sensored design, I wonder if there is better control. The key word here is "comparable". I have a Novak SS (considered old-school now lol) in a xx-4 buggy that is geared so as not to bother the esc and it is like a prescision knife around the track. If that kind of control would come with 6s capability and less fuss about gearing then I'm all for it.

Man! i was just working in san fran a few months ago! went to cap city a couple times but had to cut a deal with the shop guys to only run the 1/8 when the track was empty, so not a whole lot. Word on the touring cars too, my reflexes werent good enough to drive those damn things at speed:lol: i can see where the "smooth" would help drasticly in that situation. i think its case dependant at this point. some guys are smooth and others, well.... you know what i mean. im somewhere in the middle, maybee thats why i was impartial to either sensored or sensorless at the time. also i have heard some talk of the truggy tower on the back, is it a legit mod?, should i add it to my frankenbuggy?:rofl:

also i think roar should have their 4s class, but also have an unlimited class or mod where there arent any voltage or motor restrictions. but i can crap in one hand and wish in the other and see which fills first right?:lol:

next time im up north for work we can definately hook up and run somewhere
nothing make me smile like handing my car to someone and watching their reaction when it hits 88 mph and the flux capacitor kicks in......:mdr:

killajb- everyone loves fire right? :lol:

i guess the only way to tell is to run both. im planning on the tekin system right now, but i also have a friend that runs for associated and i will have to talk to him as well about the lrp system. probably go with the cheaper of the two. all i can say is that choices are good and the fact that more manufactures are getting on bourd with 1/8 brushless can only help the class, sensored or not.
