Way cool!
How about some before&after build pictures? :D

Bought a Castle Neu 1520 (1600Kv) for $65 from Castle's clearance sale, so the Tekin will be my spare motor or will get a new home in a custom project eventually. Probably going to swap endbells between the two though, since the Tekin already has M4 holes in it. Maybe I will get lucky and the 1520 can will have 3 more optional tapped holes in the can so I can use 6 bolts to hold on the endbell like Tekin does. Will probably just do a brushed finish on the Castle Neu also since I don't care too much for the green.

Haven't done much to my MGT yet but got a few more ideas for it. Also, probably won't be seeing a billet version of my motor mount for a while. I had signed up for a machining course at the community college here and last word was that it was going to be canceled because the instructor had to take a family leave or something like that, and I just don't have the experience or skill with my mini mill to try making something like that right now. I'd rather know how to do it right in the first place than experiment and screw up $60 3''x3''x3'' cubes of aluminum in the process. So in the mean time, I will get more practice by machining my current motor mount, and hopefully achieve a look similar look. Probably going to weld on the mount in some areas to build it up and then machine it back down to get a more uniform surface.

I'm kind of disappointed with Castle. I ordered my motor from them over a week ago, I got an order confirmation but still no shipping confirmation.... I'll give it a few more days before I email them, but with as good of a customer service experience I've had with them before, this seems very unlike Castle's usual ways.

1) This should save you some money if you plan on making a one piece unit.

2) Thomas or Patrick of Castle said they had received over 400 orders last week... they are just backed up. Did you happen to order a 1518? They sold out...

Could Delrin or wood be used as a substitute for practicing with the mill ??

Krawlin · 12.04.2010, 06:17 PM

Delrin would make a good substitute, less messy than wood (shavings/chips rather than dust), but I think the main thing I need for my mill before I make a billet motor mount would be digital read outs, and more practice. Currently I am working on modifying some parts for my MBX5T, so I am getting some more practice in before I work on my steel MGT motor mount. I'll probably start on it tonight though, so I'll post up some pics tomorrow.

Hi

just a little message for those who want a CD mount
My friend made some
if you want one send me a PM, and I give you his Email (he don't want hundred spam...)
It's not a business, so there's just a few kit made
and I don't take any money in it, just my friend for his work...

and Krawlin' I'm waiting to see what you gonna do with this milling... I'm sure it'll be great !!

hey,

Love what you've done with this build (both of you) this thread has given me so much inspiration to do a similar mount for my LST XXL. Just wondering if there were any updates as i am planning on buying a mill as well and if i see some pics then that would probably seal the deal for me.

Thanks,
B-M

Scott_T · 01.12.2011, 02:59 PM

Just registered after reading this thread. I think I might want to follow this conversion for one of my mgt's...

My kids are running electric and I think it might work for me also. I have tons of MGT parts, so maybe converting would be better then moving to a erevo or Savage flux. I've always liked the MGT platform..

I Could probablly fund the project if I sell a brand new in box MGT I have. It is the first one, with the .21.

Gonna hit thedude on a mount...

Thanks for the great thread...

Scott, save yourself a little grief and pick up the RC Monster "universal diff/motor mount". And have Mike whip you up some battery trays. It's always better to deal with an actual company vs. an individual.

P.s. Welcome to the forum

Thanks!

I highly encourage buying a mill, its one of those tools where once you have it, you will wonder how you lived without it before! Although its been too cold out lately for me to use mine much (garage isnt heated), but it will see alot more use this spring/summer.

EDIT: I have a thread in the general section about my mill, here is a link, will give you lots of good info - http://www.rc-monster.com/forum/show...ht=Mill+Review

Would be cool to see another MGT converted, I personally prefer the design over a Savage, and the MGT is basically what the Maxx wanted to be but never was (unless of course the Maxx is like 100% UE parts, lol). My MGT was also an original .21 version, it's about 6 or 7 years old now.

The problem with using an RCM Universal center diff motor mount in an MGT is that it is a bottom mounting only type mount, and the lower deck portion of the MGT chassis is rather thin, I wouldn't trust it with any motor larger than a 1515 when mounted to the bottom deck, unless one was to use an extra plate for strength. TheDude's motor mount is both top deck and bottom deck mounting, and mine is top deck only, both are stronger in an MGT application than RCM's Universal center diff motor mount. Don't get me wrong here though, I think the RCM mount is great, it's just not the best choice for the MGT. I figured that out the hard way with my first 3 motor mount designs which were all bottom mounting.

EDIT: Also, I believe the RCM mount's bolt pattern is too narrow to attach to the MGT's lower deck, so one would have to have the RCM mount bolted to a plate x size which would then be bolted to the lower deck.

Double EDIT: I bought some GPM aluminum bulkhead/diff cases for my MGT, just got them in the mail a couple days ago, talk about beefy! These are setup to use 3 8x16 pinion bearings and have replaceable lower hinge pin bushings. Good quality, I'll get pics when I do the install, which might not be for a while since I'm working again.

Scott_T · 01.18.2011, 04:02 PM

I hit the dude about a mount, waiting for a pm back....

Just trying to get a grip on everything I need. I have every MGT part imaginable, but now it will be a motor, mount, center diff, dogbones etc.......

I really cannot wait....

hi ppl,

i'm visiting this page for some time to learn with all of you about converting theMGT to electric and now decide to convert mine and share with you my work.

this the MGT i have

it's an original .21 MGT with a chassis with same dimensions.

allready have a motor mount made by dude friends (my special thanks to dude and his friend) and i´m thinking to use the Slipperential™ 1/8 Center Slipper Diff sold by rc-monster.

i will use a mamba monster esc and a motor that i can't discover a shop to buy.

any one now where i can buy one of this motors:

- Neu-Castle 1518 1Y 1800kv
- Neu-Castle 1520 1Y 1600kv

and can any one explain me something. i all of you (al least who put pictures) use 2 lipo pack 3S instead of 1 lipo pack 6S if the price is the almost the same?

more photos when i receive the thinks i order

thanks for your example. very nice work. congratulations

Awesome chassis, haven't seen one like that before, who makes (made?) it?

I hate to delay yet again, but I just haven't had time to work on this truck very much lately. However.....

Some of you may remember I was planning on making a motor mount from 1 solid chunk of aluminum... That will be happening within the next couple of months. Still getting some practice with my mill, but I've got everything picked out that I will need on McMaster, will be ordering pretty soon, so hopefully I can have this truck up and running by the end of March.

I am also trying to figure out where I can get some battery boxes like the Savage Flux has, but in a shorter version, as I don't think I could shorten them without ruining them. I want to use trays like this though because I am going to mill out sections of the chassis so the batteries would be closer to the center line of the truck and narrow it up a little bit (stock stone guards make the body seem really wide and the arms really short, which I don't like) so I can run a narrower body for a better look. Anyway, feel free to chime in on this, if you know of anyone who has shortened Savage Flux battery boxes to work with another application, post up some pics and how well did it work?

EDIT: I would also like to add, the reason I am not going with a simple flat tray with velcro straps to mount the packs in a similar configuration as the Flux boxes is because I don't really like the look of having multiple velcro straps holding each pack in. Just doesn't look very clean IMO.

Scott_T · 01.21.2011, 12:04 PM

Nice chassis NMS....I think you are on your way. I am trying to get the dude to get a price on the mount too....

I was going to go with a Mamba Monster also.

I am curious to see how the slipperential works...Getting the MM mounted then to a center diff is the parts I have to figure out in my head.....

Jealous of you guys already there......

So much so I started looking for an LST2 roller to convers as I am pretty sure parts are more easily available.....I hate to go to a new truck when I am deep with the MGT, but not being able to get a mount is killing me.,
