is anyone using a motor mount above a center diff

[magman]

With my conversion...T-maxx...I am considering mounting the motor above the center diff because I will have to lower the diff below the chassis so much that it may be easier to mount the motor above the diff...I think...anyone have any pics for some ideas...

thanks

Mike made me something like that for my Hyper8 buggy. For pics, check out the BL Conversions link in my sig...

Brian, I tried to find pics in your sig...no luck, anyway, /as long as I know Mike can make me one I will think about it some more.

Thanks

It's the BL Conversions link. Then, click the Hyper8 link in the menu. Anyway, here's what I was talking about:

I made two center mounts for my mp777,
I have yet to run the buggy (just finally ordered the cells), one is similar to the pictures above, only i started with 1/2 thick Aluminum and milled out 1/4 of it leaving a 3/8 around the edges, then milled the area around the motor itsleft to only 1/8 thick.... I will try to find some pictures... I accidentally cut the screw slots alittle to close to the motor hole, so I decided to try using come clamps form mega motors to mont on the casing of the motor instead of the endbell (check my early posts in the buggy section for pictures)

Thats a nice way to run 2 batteries. I was thinking about a mount like that to run a center diff in a lst chassis.

I am! Mike already made that mount for the e-maxx, but it would bolt right up to the t-maxx here's the link:

just needs a little dremeling where the spur hits the chassis

I want that motor-mount like is on that FLM chassis so bad it's ridiculous!!!!

Hey chad why dont you start making those whey you get your mill. I am sure alot od people would like to buy them and the profits would likely pay for the mill over time. I have emailed mike multiple times to get one of these made never get any reply.

This is my own custom made setup.

I used a Gorilla Maxx motor mount, OFNA center diff(K-Type from an OFNA Ultra LX One or OFNA Ultra MBX Comp) with 51 tooth spur, and Integy center diff mounts, and a T-Maxx 2.5 chassis. I cut the motor mount and drilled a few holes to attach the motor mount to the center diff mount and made a Lexan top plate with 2 pieces of 1/8'' Lexan plate. To get the screws that hold the motor mount to the center diff mount to not hit the spur, I had to dremel about 3/32'' or 1/8'' off each corner (on the flat surface). I had to dremel the chassis and lower braces some to get the spur gear to fit. And to prevent from bending the motor mount on hard landings, I made a motor support with some 1/8'' Lexan plate. The whole setup is mounted on a Golden Horizons center skid plate, had to drill 4 holes and I elongated them so I could adjust the center diff position so my center driveshafts wouldn't bind, and I used an OFNA dogbone for the front center shaft and a rear center CVD for a 3906 E-Maxx as the rear center shaft. Also, since the screws are not threaded into the motor mount, but instead have a nut on the end, I could not get my motor to even fit on my motor mount, so I used 2 brake discs from my OFNA Ultra MBX Comp to make a couple of motor spacers. They just happen to have almost perfect hole spacing, only had to drill the holes out just a little bit, and I cut them in such a way that I can adjust the mesh to any setting the motor mount allows for.

This may look kind of hack, mostly due to the fact that I don't have access to any kind of a mill, just a drill press, a Dremel, and various hand tools, but I have been running this setup for a couple months now without a single issue.

Finished Product -






Center diff mount and motor mount




Dremel'd chassis braces and skid plate with elongated holes for center diff position adjustment


Center diff mount and motor mount installed, with motor support in the background


Motor spacers



You also have a couple of speed control mounting options with this setup. The way I made the center diff top plate, the ESC can be mounted like in the picture below, with the receiver being at the right front of the chassis -



OR you can mount it like the picture below, with the ESC at the right front of the chassis, next to the motor, and the receiver at the very back of the truck, far away from the motor and ESC for less interference for those of you who run AM or FM -



Hope this helps!

River, I do plan on making some things like that when I get my mill and learn to use it well! :)
