    Motors, 550 vs 540, what's the difference

    I would like to know the important differences between 540 and 550 motors. I know that Emaxx trucks use 550 motors. Recently, I got a Stampede. The way I understand it, Stampede's can run on 540 and 550 type motors? So, when I am looking for a faster motor, should I be looking for a 540 or 550 replacement? Are 540's faster because they are smaller? or drain less power from the battery? or are 550's stronger motors? I see many cool motor options, 15T, 17T, Amber speed gems, etc.. Some are 540 and some are 550 motors. I would like to understand why I am choosing a 540 or 550 motor replacement. Thanks to all.

    550's are longer, and are slower, with more Torque. If you have the xl-1 esc, you can only go down to 17 turns. The Speed Gems Amber 17t is a great motor for the pede. Most 550's are 14.4 volt motors (except for the Titan 12t).

    Thanks "kschauew". I have a new stampede with the XL-5. My truck had a bad titan 12t motor, so its already been returned for exchange on a new one. I put in a spare titan 550 motor that I had and the truck can do wheelies on demand. Yep, a 23turn motor will do that, especially titan's. But, my top speed takes a big hit of course. I was looking for a good fast motor, but, without losing a lot of torque in the process. Can anyone recommend a happy medium? A fast motor, with an ample amount of torque, is what I am looking for. So 540 motors run faster. They must have a faster turn cycle?

    Here is a great place to see the latest motors from Trinity. They are not the cheapest motors, but represent all the motors in the hobby.

    This Streat Freaks Backyard Basher seems like a good choice.

    One good thing about sticking with the stock Traxxas 550 12T Titan motor is that it is nearly maintenance free, has the built in fan, and is inexpensive.

    Why don't you try a new 7 cell battery first with the Titan when it gets returned?! Based on what people have been saying in here, the stock motor really hauls with 7 cells. And of course try to get a top quality battery pack with Deans connectors from a manufacturer like IB or GP. Be sure to play with the gear ratios before getting a new motor too, IMHO.....

    Oh to answer your question, 550 motors really come from the power tool world, like cordless drills. Nearly all the other motors in 1/10th RC are 540's. In theory I suppose you could say 550's are more industrial and more torque. 540's have been the motor size since RC began for the most part, and come in endless variations and prices.

    What ESC's would be a good matchup for these motors?

    Those look like some nice motors you picked out, I havn't tried them but from a name like trinity I'd be willing to bet they are a very fine product. Associated has some nice esc's, except stay away from they're line of "A.I" speed controllers, I bought one and it burned out within a month. A lot of people have had the same problem. Novak makes some nice esc's as well. Such as the "rooster and super rooster". Futaba makes a good esc but the lowest it will handle is 13+ turns. Here is a page that shows a few of the reversible esc's. http://www2.towerhobbies.com/cgi-bin/wti0093p?&C=MJD

    A few things to ask first. 1. Do you want to run only 6 cells, or have the ability to run 7 cells or more? 2. Do you want a waterproof ESC ? 3. Do you want to have fancy features like adjustable drive profiles etc.? 4. Do you plan to formally race? 5. How much do you want to spend?

    You really need to answer those questions to make the best choice. But as far as general gossip goes, the Novak XRS is pretty popular and well liked in this forum of Stampede users.

    Here are the website specs on the Titan 12T 550 :

    Here is the Warranty policy of the XL-5 ESC to compare to others.

    So 85GTV84FUN, if you stick with the stock XL-5 ESC, then you can use any motor in the smaller 540 size, as long as it is over 15 Turns. Seems that 17 Turns are about the best balance of torque and speed.

    Racerfan120, I think those "Street Freaks" motors are fairly new, I don't recall seeing them last year, I just found them myself.

    What model LRP ESC did you have that burned out?? Did you get it wet ? Did you get it repaired under warranty?
