I am Deciding Between the Associated LRP Sphere Competition w/ Vector X-11 7.5T motor, or the Novak GTB/Velociti Racing Brushless System 7.5T

The application I am looking to use it for is an Associated RC10 T4, which is a 2wd stadium truck.

It's a hard decision, I picked the Novak because I already have it.

I voted lrp, since you can mess around with the timing of the motor

Novak has better motors, LRP has had quality problems with their rotors in the past while Novak's have always been rock solid. And now with options like different rotors, L-series motors, etc. As for the ESCs, LRP does have a parameter that lets you change the timing (the sphere competition does at least), speeds things up slightly but makes the motor get real hot. In practice it's better just to change gearing, except maybe for the stock brushless class. But Novak has some useful parameters on their latest ESCs also, and you would probably get better service with Novak also since they are local. So overall I think Novak's combo will be the better of the two.

I believe that LRP is local too, they don't outsource if that is what you are saying.

Can both systems be programmed on the computer?

ElectricGuy007

Nope, only the mamba can do that at it's iilegal for racing.

speed racer 12

Oh really, I had no clue. Well, i guess that makes the Mamba systems great for bashing then.

No, ROAR does not say anything about ESCs, only motors. You can use the mamba ESC and a Roar-legal motor with some minor modifications, and it would be legal.

j.m.

the lrp is by far better, but that comes with a pricetag. That's why i can only dream about them.

My very first post!

Speed Racer -

I had to vote Novak because, well, I just bought my very first Novak GTB 6.5 Brushless System. It will go in my new Associated T4 that should be arriving in the mail soon. I have been out of this sport for about 15 years and I'm looking very forward to getting my hands on my new toy.

Thanks,
David

OK, j.m, What makes the LRP better? everyone else is kinda saying novak.

That is right, the mamba esc is ROAR legal! It'sthe Mamba motor that is not legal because Castle has not submitted one for approval. The blame is all Castles!

Who would want to race with a sensorless system anyway where it will not be no where close to being as good as a sensored system on a racetrack.

Craps

Why would you want to have to program the esc on a computer when you have all the power in the radio to dial in the esc/motor combo????

speed racer 12

Because, it controls 7 parameters, including brake power, drag brake power, acceleration power, horsepower tuning, etc...

Did you read the ROAR rules for 2007? I already posted this to another thread, their motor would not pass approval even if they submitted it. B'cos it does not have their name / logo etched on the end plate, and the screws on the outside of the body cause the diameter as measured to exceed ROARs legal diameter. There are other issues with the rules like measurements for the rotor, but those are two major ones.

speed racer 12

hmm...

Craps

My Futaba 3PK radio does all that right in my hand with the Novak system while it is on the race track! No need to run back and forth to the PC to make changes!

speed racer 12

A 3pk can do all of that? Damn! That makes those things worth the money then!

Craps

I don't even know why a basher system like the Mamba is even bought into the discussion that is not even close to the 2 sensored systems that are made for racing. It is like comparing a Chevette to a Corvette, the Mamba is not in the same class as the LRP or the Novak!

Sensored is for Racing!
Sensorless is for Bashing!

I am a Novak man and the only thing I don't like about the LRP is it's longevity will not be as long as the Novak because of it's size. The LRP is small and with heat and cold cycles the smaller electronics will break down faster over time. We found this out in our 20 minute main electric races where the LRP is very competitive with the Novak, but over time it goes away and develops problems.

Do not get a brushless motor unless it has a sintered rotor in it. The bonded rotor ones heat up quicker and do not last as long.

For off-road on slick tracks, I highly recommend the new Novak 7.5L or "Lite" series motor over the 7.5R that is the older one. If you want a brushed motor comparison the 7.5R=15 x 1 and the 7.5L=15 x 2 with the "L" being like the double wind 15 turn is smoother on the bottom and still has the same top end power.

speed racer 12

Cool, i will check out the 7.5L, I didn't see any of them on tower hobbies though.

speed racer 12

OK, I found the 7.5L, but it does not come with an ESC, I am looking for an ESC motor combo, I could buy them separately but it would probably cost more.

ElectricGuy007

Yeah, the GTB fan is nice to have included, but I've seen the Sphere Competition and it doesnt need a fan.
That makes a tiny bit of less weight.[8D]
I'll proabably end up having both like some people at my track have all 3 types.
But the mamba is way too powerful for me.[]
I dont see how people can control the mamba 7700Kv.....quite rediculous if you ask me...

ElectricGuy007

Hopefully it wont matter much since I got the older 7.5R.
My B44 tires are balloning at 60% throttle on my radio. Just was testing it a couple days ago....wicked fast....
Dude I'm just experimenting anyway, really wanting the team checkpoint brushless motor, have you seen that sucker...
Looks Sweet!![8D]

Craps

The "Lite" series or "L" motor has been out a couple of weeks by Novak. I am a Team Novak racer and got mine early.

I am using the 7.5L in my T4 and the 5.5L in my B44.

Sorry, but i don't think any combo deals are available at this time with the "L" motor in it.

You guys want some good deals on RC equipment including Novak go to www.carolinasrc.com for the best deals and please use the discount code on the front page to find the cheapest Novak systems on the net with some items include free shipping. I know they had the cheapest B44 kit for under $285 with free shipping and sold out real quick!

Great forum there too!
