A guy at the local track showed up with a mamba max in a xxxt and i got a chance to compare it with my basic 5300 in the b4. I pretty much decimated the mamba max out of the hole (but i am running a gyro :D ) and the basic spooled up faster, i also got better top end (my car was radared at 36mph), both motors are way to fast for the small track we run on. b4 6 ib 3800 cells 21/78 xxxt 6cells i think he had a 17t pinion and maybe a 89t spur

Isn't that kinda apples and oranges (buggies and trucks)............?

5700, (read the title).

The LMT 5300 is an impressive little motor, hard to beat for its quality and efficiency. Plus it is rated under load unlike almost all other companies motors. But it is kind of apples and oranges, since a buggy will beat a stadium speed wise with the same motor.

Yeah i know, and i was also using better batteries but the race wasn't even close and i was kinda expecting the mamba max to have more power.

Well....if you're using better batteries...I wouldn't expect the mamba to perform where it could have at all. What batts was he using anyways? :confused:

I don't know what they were but they sucked.
What's up Buggy Man and the rest of the forum...
I should be able to clear this up, being that I'm the owner of the XXX-T.
The batterypack was an old rusted NiMh pack that was included with the used XXX-T I bought. I'm sure it's been through way too many cycles to be of much use anymore.
My truck had completey bald, worn out rear tires with a couple holes in them from being thrashed by the last owner, plus they were dusty from messing around on the concrete near the track.
Like Buggy Man mentioned, I didn't have a gyro and couldn't even give it half throttle from the start without it loosing all grip and spinning its tires or spinning out.
The mamba speed controller was using default settings
The pinion was an 18 tooth (not sure about the spur, but i think it's the stock one)
Needless to say, my gyro is on the way and I'll bring better tires and batteries next time. The only real way to test the motors is to put them both in the same car with the same setup. No doubt it was a completely useless race for comparison purposes. It was fun though.
To be continued...

That somewhat explains it. Throw some new rubber on there and pick up some good quality batteries, then you'll have a reasonable comparison for power :)
Btw..you guys use gyro's? Hows that work out?

Gyro's are awsome and they let use alot more power as long as u set 'em up right.
What gyro did u order?
The x-drift off ebay for $39.
And my friend who was there ordered the Futaba gyro hoping it would work the same: http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXKTT2&P=7
We'll see...

That thing's for helicoptors man, i don't know if it'll work.

Just to clarify, you willingly pay $40 for and install something that interferes with your control of the car, akin to traction control for RC?

It works off the same principle though, so it probably should. They all use the movement of the car/heli to adjust a servo...
I'll let you know how it goes.

What needs to be clarified? It helps it to track straighter. It's just a hobby, man... we drive around little toys. No need to be a purist.

Thank you for the clarification. That explains A LOT.:)
If you want to use a gyro, more power to you guys (certainly a cool concept). It'd be a waste for me because I just bash though.... Uncontrollability is fun!!!!!:D

Glad to see the real side by side equipment has been posted - personally I think the first post should have included it, the subject is rather misleading. You gave a comparison of the motors but what value did it really add without knowing the details of the rest of the equipment?
The batteries are truly key to a high performance system and if you want to compare brushless systems side by side you need to atleast get them close battery/car/tire wise.

B-RO, chill man. I just don't see the point in letting a computer do the fun stuff, whatever does it for you though. I'm all for experimenting, I just don't see how you can get more fun out having a computer keep the car in check.

No problem on the clarification. I knew it'd be a rediculous race, but tearing around a parking lot is always fun after a night of laps around a dirt track.
They gyro isn't really for racing (for me anyway). I'm just going to use it to mess around. I love driving my cars with no fancy electronics while racing on the track, but for messing around and going crazy fast on dirt or street it could only make it crazier. Once you see one in action, you'll probably understand. It's not something that drives for you. It's just a stabilizer. When I want to punch the throttle and have my car take off as fast as possible while bashing, $40 doesn't sound too bad. If, for some reason, it takes the fun out of it, it's a simple part to remove.

Racers used to have gyros built into there speed controllers.

I was just speaking for myself there. That's not what I bought it for. I personally woudln't want to race with it unless everyone else was.

this is a very interesting concept.
On one of my cars academy sb it tends to torque steer very badly due the weight reduction from lipos and a more powerful than normal powerplant.
I wonder if one of these devices would help me in this case as hopefully a gyro would counteract this.
by the way buggy man what gyro are you using?

I run this gyro http://www.rcmart.com/catalog/product_info.php?cPath=421_36_616&products_id=16428 but a gyro won't fix torque steer, it might even make it worse.

I assume this gyro will help keep the rear end of the car from stepping out by counter steering.
The sort of torque steer i talk of normally results in a spin out if i dont back of the throttle.

That's exactly what a gyro corrects. It should work for you. Maybe that's what you were saying, but just in case.
BTW, just in case you're not sure how it works, check out this video. The first part of the video where the guy is holding and moving the car is the helpful part. The rest is just drifting.

Whatever you do, don't buy the HPI one. You'd be paying over 3 times too much.

Then that's not torque steer, thats the opposite: fishtailing or excessive oversteer and the gyro should help u out.
Why are we even talking about torque steer on an rc forum? Unless you're driving a front-wheel-drive vehicle, there's no such thing.
Just a mix-up in terms I'm sure.

Having the motor mounted horizontal relative to the direction of the car results in torque steer. I had it in my old TC3 when it had a powerful enough motor in. Its one of the reasons most tourers these days are belt driven, because then the motor is mounted inline with the belt.

I can see how that would have a similar effect. Actual torque steer is when the torque from a front-wheel drive vehicle causes the front wheels to pull to one side or the other. When you have a rear-wheel drive car, the motor doesn't affect the actual steering of the front wheels. A strong enough motor though, like you mentioned, will pull the car off it's line regarless of whether it effects the steering, resulting in the same problem.

Yup. I don't think theres any RC specific term for it so its just called torque steer because the end result is the same. It doesn't directly affect the steering but will pull the car to one side which requires slight countersteering. So one of these gyro thingies would likely help.

I know you guys are all off topic and stufff.... ;) but....
Not only are the batteries huge, but so is gearing. I think the xxt is undergeared if you want to see how much power is there. You don't know until you experiment with it but my gut says you are not tapping into the real ability of the max yet.
(of course you must get rid of the horrific pos rtr batteries, or don't bother trying to do any sort of test/comparison :) )
I always wanted a basic motor and never have got one.... my xx4 would love a 5300 and 2s lipo. or 3s... :D
