Brushless help
 

I am looking at getting a brushless motor for my E-maxx, basically stock. I have kind of looked at the HV6.5, but it looks like an XL might be better way to go. The main thing I am looking for is maybe a little more speed, but mainly longer run times. I would like to stay with 12 to 14 cells. Any suggestions? What all do I need if I go with an XL motor? How much am I going to be into it? I'm guessing $300 to $400 right.

I have 3.3 revo shafts and carriers on the truck. And I will at least get the steel idler gears when I put a brushless motor in my truck.

Would the Quark 80B esc controller work with a Feigao C 8XL or C 9XL if I stayed with 12 to 14 cells?

So it looks like I will go with: Feigao C 8XL or C 9XL, Quark 80B, steel idler gears, Strobe slipper

Thanks for all the help everybody!! You guys are awesome!!

depends how mutch you want to spend jim, yes the XL motor are good you can choose from ither the wander XL's or a fiego C XL's your definatly going to need a ubec. In my opinion i would go for the wander with a rc-monster heat sink, choise of motor would be an 8XL because the rpm range is good for 12-16 cells i belive.

if you want more power less cogging and far better eficiency then an XL you could go with LMT 19 series but cost a lot more then a wander of fiego

welcome:D

First off, welcome to the forums! I would definately choose the Feigao XL C motor over a Novak. If you can swing it, a Quark 125B is the best, but a 9920 will certainly do. CVD's, or the 3.3 setup is a must, and a UBEC is a necessity above 12 cells. Aluminum diff cups and cases are a good investment, but the FLM hybrids with Hot Bodies Lightning diffs are the way to go. A little more, but you never have to worry abou them again.

Edit: Mike, why would you choose the Wanderer? It cost more with the heatsink, and just as much without...No differences what so ever other than the heatsink and the screwed on endbell.

i have to comfirm that the motor is from rc-monster. :D your right the fiego C XL motors are better in some ways. to me it wouldn't make a difference if i had the wander with a heat sink or a fiego c XL.

It might if you saved 30 bucks...

Does the c can clear the trans mission on a truck?
If you looking to only get a little more than stock with out a lot of work.
The 10L may be a good choice. It will still be more than the hv. I would
recommend getting the steel idlers at least. The diffs should hold fair depending
on tire selection.

Welcome to the forum to.

if your going with the 10L your definatly going to need a heat sink on that!

I would use squee's choices. He's a good motor guy! LOL, fiago c xl

Would the Quark 80B esc controller work with a Feigao C 8XL or C 9XL if I stayed with 12 to 14 cells?

Yes it would. But as Squee suggested, you would need a external ubec. they are only like 30.00. Get one from Mike. I think anything over 10 cells.

Oh, one last thing. What gearing for this setup? And is that a 5mm shaft on the feigao C 8XL?

I believe it is 5mm, but double chekc on the site, that'll tell you foresure. Gearing depends on what your runing it in. if you are running 32 pitch, 12/66 would be a good starting point maybe, or 51 mod 1, 16/51 is a good starting point. But again, all depends on what you're running it in.

You need a UBEC above 12 cells. I have run one on 14 but wouldn't suggest it. It would certainly spell certain death eventually. The 80 would be ok on a 9XL for sure. You would have to gear conservatively on a 8XL, but I'm sure it would be ok.

Are you sure squee? I could swear my manual said 10 or above?

If you run the 9xl on a 80b quark you have to gear down some. If you go with a 125b you can do little better on gearing choices. I had the 9xl on 6s geared 13 51 with ue diffs with 2 speed. If ran to hard it would thermal.

Your right, it does say 10. I saw somewhere around here that it was 12 :032:.

What do you reccomend for a slipper?

Any cell count above 5 (6v) will create heat on a built-in BEC since they are linear. More cells, more heat. I'd rather use the heatsink on the ESC for the important part, the motor controller, rather than heat it up for the BEC function. I'm only running 6 cells (and 2s2p Lithium) on my Mamba max and I am thinking about getting a BEC since the heatsink on the ESC is so small. Just a little extra insurance. Plus, a digital BEC is more efficient and will help increase runtime (albeit negligible I'm sure).

Go with a Strobe slipper if you can find one.

Any other slippers that will hold up to brushless?

Not really. The Kipster is good but out of production as well and even harder to find. The RRP locked down with a modified Mod1 spur is the next best thing. I would assume you can modify a Ofna spur for the Kipster as well since it uses the RRP spurs.

Not trying to be picky, but I think that you might have the pinion gear switched around (12/66 - 5.5 ratio, 16/51 - 3.19 ratio)(16/66 - 4.13 ratio, 12/51 - 4.25 ratio).
