Click here to view the full version : Best XL-5 compatible motor?
Hey guys, I've started something kind of different here. I built my own r/c chassis and A-arms out of some solid hickory at work (dad's a cabinet builder) and I plan to built as much as I can out of steel and wood. I have an XL-5 ESC I'd love to use and I have Stampede tires and body and I'd like to use atleast the tires and ESC. So I was just wondering what the best XL-5 compatible brushed motor would be. I've heard that the Titan 12T 550 isn't a very good quality motor so I'd like some of your ideas of a good brushed motor. I'm not building this for toughness and speed but just the idea "that I built my own r/c" would make it all the more valuble to me. :)

I have heard that the 15T HPI Firebolt is a pretty solid motor, also the Stock AARMA 15T seems to have plenty of kick, perhaps they are the same motor? I dunno, I have just heard many good stories about them.

Probably the best motor within the limits would be something like a 13t modified motor. Seen a video of one of those and they really are fast!
something like this:
Edit: forgot about the 540 limits, sorry, so get something like this instead:
Okay, thanks for the replys. I'll do more researching on the 3 and see what the final "results" are. I'll let you know what I'm looking at.
I think 15 turns 540 is the motor limit. It can handle a 12 turn 550 because there is more wire per turn on the armature than a 540, and therefore less speed and less current draw.

also remember that a heavier car will require more torque, i think a 27t motor would be the ticket.
So Fier_Man_121, what motor were you thinking about when you said 27T motor would be the ticket. But if the XL-5 ESC has only a 15T limit then.....what then?
What about the Titan 21T motor that's in the Emaxx, I guess that would be to many turns but it sure would have more torque for the heavier r/c.

You dont want to use the emaxx motors, they are a 4s motor. Ive heard good things about the firebolt 15t, and it is cheap too. Is there a reason you dont want to run a titan 12t? With a water break in and lipo I think they are pretty impressive.

less turns, hotter motor, more turns, slower and torquier (is that a word)
if its just a cobbled car an ole 27t will do. axial makes a non-rebuildable silver can
Well, I guess the XL-5 ESC, buy the way it sounds, has a 15T limit and I'd need something more, probably.....sigh...... If I would use the 15T firebolt would it be compatible with the XL-5 ESC? Turboshadow, I've heard that the 12T Titans are not the best quality. I went through 3 of 'em in my Stampede in a year but since I'm not going to be doing with this r/c what I did with my Stampede then I guess it might work. What do you mean the "water break in". I'd like to run lipo because they are lighter with more punch.
Anybody...?...is the HPI Firebolt 15T compatible with the XL-5 ESC? I'd probably be using this lipo battery.

Yes but why that battery? 1600 is small and probably wont put out enough amps and will puff. If you on a budget, but this one.
Less then twice the price and almost 3 times the capacity. I have 4 of them and really like them. My xl5/titan rusty loves them :)
Alright, I was going with the higher C rating for the motor's sake but if this works good for you, I'll def. give it a try. Thanks.

1.6AH X 40c = 64 amps the battery can put out
4.0AH X 20c = 80 amps the battery can put out
So, the lower C rating, but higher mah pack will last longer and have more amperage available. :)
Thankssss, very much. I'm not a very smart person in that area if r/c LOL

Everyone's got to learn somehow man.
I am so excited about continuing on my homemade r/c. I have mostly everything planned how I'm going to do it but I could easily be missing something. These are the only things I'm going to be buying.

And then some gears and connectors. If you have any better ideas that what I have listed here, let me know. :) I am planning to buy the items from ebay tomorrow or sooner so speak up if you have a better idea.
If you can afford it, go with a Gens Ace 5000MaH 40C LiPo (direct version) from Hobbypartz. Everyone seems to like those.
I'm on a budget and that's the reason I'm building my own r/c. Does everything else look like good choices though?

I really think you would be better of buying a used traxxas 2wd roller of some kind and then modifying it, instead of starting from scratch if this is your first custom build.
