BPP Wraith Motor Question (quick and simple)
 

Anyone know if it has a pre-ground flat spot, or is it round like the Mamba 20XX motors?

im pretty shure got a flat spot, because ppl break the shafts when using high voltage... idk tho

Break the shafts??? Thats no good...might have to just stick with Mamba Motors, since Castle would probably replace the motor if you broke the shaft.

troy at bpp will replace the motor also...

new one + 4 cell lipo= instant snap

3 cell + new motor= a while of running, as long as u have a slipper or something

and 2 cell is fine

yep, flat spot.

Ok, thats good to know that he will replace it...

I'm going to run 3S lipo so it should be ok. This is probably going in a friends truck, so thats why I asked.

yeh, over time it might get weak, but troy is cool about it

Well, it's really my friend's choice. He's building a Mini-LST (well, I'm actually building it - but he's paying for it and its his truck). I was thinking of building one with him - but I think I'm gonna do the CRT .5 instead.

Anyway, for the Mini-LST, we had 4 options to choose from.

1) Mamba ESC with Wraith Motor on 3S
2) Mamba Max ESC with Dual Wraith Motors on 3S (but not possible, since the flat spots will prevent the possibility of perfectly matching the phases).
3) Mamba Max ESC with Dual Mamba 5400's on 3S or 6800's (or 8000's) on 2S (Possible since they have no flat spot - and the non-flat spot hasn't been an issue with my 18T, which runs 3S lipo).
4) Full Mamba Max 5700 (or 6900) system on 2S lipo.

I wonder if Troy can get me a Wraith motor with no flat spot...I'll have to shoot him an email.

I know options 2-4 just seem insane and somewhat pointless, but he wanted 50-60mph and I know those setups will give him it.

1 is the only good one... dual is stupid, and all it will give u on a plus sied s better acceleration

u wont be the first person to do dual motors in a mlst, most ppl did hyperions, and a few of those c4 motors

imo DUMB! all u have is more wieght, less runtime, more heat, or less depends on how well u can match them, and alot more strain on the drive train

Nah...I'm pretty sure top speed would be increased with two. BTW, the two will be ran off one ESC.

Running dual motors off one ESC is just like running a more powerful motor.

Anyway, at this point we are leaning toward option 4...since its easily the most powerful.

its dumb man!

get a lehner, more power then 2 motors, and probably cheper because u dont need 2 bats and all

Who says I'm running two batteries??

This is going to be exactly the same as a single motor setup, besides the fact that the second motor is wired in with Y-adapters.

Plus, it will also have better balance this way :)

If you really feel that strongly against it then I guess we can just run the MM system...but I think thats going to be way overkill in a 2.5lb truck.

well run times will be like no time lol

if u want that much power just get a lil lehner, a few ppl have them in there mlst's and love it waay more then a wraith


but yeh i really dont think u should do dual motors, or a mm, bolth is just dumb imo, no offence or anything but if u have ever used a mlst with a wraith and a 7 cell batt u will think different, then 2 motors and a 3 cell WOW!!!!!!!

BPP says a stock MLST does 44mph with a Wraith on 3S. My friend wants 50mph...

We'll see...most likely we will end up with option one cause I'd be too lazy to do anything except bolt things together LOL

Also, battery will be anywhere from 2200mah to 5500mah in increments of 1100 - depending on the setup. We will adjust to get the runtime we want (shooting for 1 hour).

I guess we could try a lehner, but I'm not so sure he's down with spending like 200 bucks on a single motor (any of the setups above would end up costing 200 total, while option 1 is just a little over 100).

no its like 140 for the right one

and come on!!!! u cant drive a darn mlst at 40 mph! its unstable as heck lol

plus with a lenher, 50 mph could be done with a 3 cell, run cool, so u could gear it up... and be lighter then a dual set up

Yea...I think my friend is just looking at "oh - 50mph!!"

This is cause he sees my G2R do 40 and stay rock solid - but what he doesn't understand is that I spent a ton of time setting it up and the CG is a hell of alot lower.

I'll just probably set him up with the Wraith on 3S...

LOL tell him its a 50 mph set up:005: whats the diff??? lol once he gets to 35 he will be like WOA!!! its going a 100 mph, so it seems

but yeh a wraith, and 3 cell will be more then enuff

Wrong. it's less efficient.

i am pretty sure 1 wraith can shoot that lst at 50mph with the right batteries.

i thought it didn't had a flat spot though.. can't remember it though..

thats what i thought, the speedo will run hotter, and less run time
