How to take apart your Mamba 6800 motor...
 

1. Take your appropriately equipped Mamba 18th scale vehicle out to an open road early Sunday morning for some high speed runs.

2. Warm up everything with a few 45 MPH runs.

3. Ease into your wide open runs, seeing 55 MPH on your radar gun.

4. Launch your vehicle from step 1 over a small blip in the road, and send it sailing into a light pole, stopping the truck DEAD in its tracks.

5. Wonder briefly where all of that energy went.

6. Proceed to walk to your vehicle from step 1, and realize the Mamba is now in more than one piece inside of the truck.

7. Rush home to take pictures with your camera phone so you can post online.

All joking aside, I realized it wasn't a total disaster, the can came off of the end cap, and the center shaft was left there as well. I looked at the end cap and saw some epoxy residue on there, so whipped up some JB Weld, was careful not to put on a ton (can't imagine that'll help things spin freely when it dries), and got it back together with some vise work (couldn't do it by hand).

It's drying now, but I did lightly drive around my apartment and it's spinning just fine.

Enjoy the pictures, and if my tactic doesn't work the same for you, post your method so we can compare notes. :rofl:

:surprised:

Ill second that!

uh, i'll triple

Mine snapped the shaft with 6S :lol:. I don't know what I was thinking. Forgot to mention the mounting screws shattered.

haha how many rpm is that?

150,960 Rpm!

even with drag and such thats got to be over 100k :D

what does that little motor sound like at that speed

Somewhere around

haha u beat me to it

It sounded good :lol:. I have to say one thing, "DON'T TRY THIS AT HOME".

same thing as running a 180 xmods motor off 5s..... sounded like a turbine, but the arm wasnt balance THAT well and yeah..

What ESC? I've got a couple xmod motors lying around.

mm on my 5s pack

I just ran mine on 18 cells and put a little prop on it. The motor was floating. It was cool.

haha

The strangest thing was the mounting screws held the end cap into the motor mount, the actual can blew off of the end cap from the impact. I never would have thought that was the problem when I walked up to the car.

The pinion was still on too, just the little motor floating around under the body.

Still running though, I just gave it another lap around the apartment to make sure the JB Weld isn't secretly inside of the assembly causing harm. Although I was excited to get a chance to buy something new possibly, I am happy I fixed what I have.

yeah if not that neu 1107 is calling you :D

Been there, done that with a similar motor. Except....my luck was worse. I shattered the rotor.:lol:

Thanks for the tutorial, is there some kind of work-around if there are no light poles nearby?

curbs.. 1/1 car tires... the little median in between doors if u have a 2 car garage... mailboxes... and the list goes on :D

replacement motor :D
