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.

2.05.12, 10:50 am
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.

2.05.12, 11:27 am
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.

2.05.12, 11:28 am
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.

2.05.12, 1:02 pm
Anybody...?...is the HPI Firebolt 15T compatible with the XL-5 ESC? I'd probably be using this lipo battery.


2.05.12, 1:08 pm
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 :)

2.05.12, 1:13 pm
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.

2.05.12, 1:38 pm
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. :)

2.05.12, 1:41 pm
Thankssss, very much. I'm not a very smart person in that area if r/c LOL

2.05.12, 1:47 pm
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.

2.05.12, 4:41 pm
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?

2.05.12, 6:44 pm
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.
