BL savage info? newb to large brushless

i was going to plunck 600 olus dollars to get my e-maxx running again but i decided that my savage was an easier way to go. so now comes were you guys come in. i need to knw what i should run that is realiable and wont thermal in a couple of seconds. i want to get the castle creation mamba max and plan to run 12-14 cells in my truck until i can go lipoly. im going to keep the reverse 2 speed and brakes from the stock truck. i want to know what xl motor to use as those are the ones i see about in these trucks. also any other things that i should get. for now i want to get the system in there and then later up grade it with lighter tires and whaty not. it is all stock except for the reverse. i want to run in the vicinity of 35-40 mph tops and would like to be able to use it in the sand as i frequent the dunes often. so any help would be great andi want to be able to get all the stuff from rc-monster. thansk alot and sorry if this question has been asked countless times as i want a good performing truck. thanks again

Hello BL_Maxx! welcome to rc-monster!

The wanderer 8XL would be the motor of my choice.

cool so it would be good for what i describe? that was a quick response and would i need to chanbe anything else from the choices i have made? thank you very much.

hey could i get some help i already have a bk 9920 controller and have been thinking an 8xl motor with 14 cells. how fast? runtimes? heat issues? would i have with this combo been reading on here all night and thats what ive came up with thanks in advance for any help and who do i need to contact to get a motor mount for it also what should i do for battery mounts


HERE IS THE ESC I BOUGHT

this is a cool new proline body that came out tonight im gonna get one after the brushless conversion.;)

well kershaw design has a nice one thats the one im going to get but im going to make another prototype one that is a little lower more beefier. but for 35 bux you cant beat it. so far i have heard if by the setup you aere going to use that it is a good one. if you use the stock 2 speed with reverse and mechanical brake it wont heat up or thermal as it is called; well thats what i have heard. i might go with a 7xl but not sure if it will heat up bad because i got a gearing chart and it said with that motor on 14 cells would go about 42mph. but i need somemore research to do. an 8xl would be maybe in the vicinity about mid to high 30 with 14 cells.and the battery mounts kershaw design has a complete kit for brushless conversions that includes them, but ussually people just make them to fit there battery configuration and what they use like mechanical brakes and such. here is the page check it out http://home.comcast.net/~milemarkers/index.html . hopefully this helped. and that is a cool body i wanted to get it for my maxx so i could use my titan body on my maxx but im going to sell the maxx instead.

thanks for the help my savage will be all black after the conversion ill post pics here when im done i might run either a 7xl with 14 cells or the 8xl with 16 cells ill ask around:dft003:

Everyone here will tell you that running higher voltage on a higher-turn motor will be better. I'd go with the 8XL and 16 cells...

[savagehaley14]

what gearing should i run and can someone show me a link to the wanderer 8xl motor thats what showed up when i used the motor calculator and the bk warrior 9920 should be good for the motor and batts (8xl,16cells)

[Serum]

I thought you wanted to use 14 cells? However; i did use the 8XL on 16 cells in my savage; i liked it, but it ran rather hot; i needed a fan on the 9920 and the motor to keep it cool.

It is possible; just use fans.

Yeah, I've been meaning to change that a little. The program assumes a 40krpm "sweet spot", but ~35k rpm seems to be a little better.

It will work, as Serum said, just run a tad hot.

And, this is the link to the Wanderers.

[savagehaley14]

so i should run an 8xl with 14 cells

[BrianG]

Yes, 8XL on 14 cells is just right. If you want to go to 16 cells, get the 9XL. You should get better runtime on the 9XL/16 cells due to the reduced current.

[savagehaley14]

is stock gearing good

i just realized can the mamba handle 14 cells with out blowing up???? i didnt take this into consideration as i see it has a twelve cell limit. could i pull it off in 14cell setup?
