MGT 3.0 Conversion

[What's_nitro?]

So- I bought one from TH, 'cause they are on sale for a VERY good price. I have zero knowledge about these trucks, so I have a few questions.

1) I hear the diffs are only 2-spider setups- How will they hold up, and/or are there ways to make them stronger? Can other diffs fit, or will 2 more spiders fit in the existing diff cup?

2) How durable is the transmission? Would it behoove me to swap in an E-Maxx tranny to more easily fascilitate the dual-motor setup I have in mind?

3) Aside from the drivetrain, what can I expect to break first?

[_paralyzed_]

1) i don't know

2) it would behoove you. the sideways motor just doesn''t lend itself to dual electric motors

3) i don't know

I see no reason that you could not do dual motors sideways? Just make a mount plate like the emaxx...

In any case, sideways motors are great, no torque twist side to side.

Damn it! You're most probably right. I just think it would be awkward looking (lay it out and see) and I like the symetry of an e-maxx tranny and I really wanted to use the word behoove.

Thanks guys. UPS expects it to arrive on Friday. I will see how much room there is and go from there. There are benefits to both setups, so I think the deciding factor will be "ease of integration".

Thats the spirit, agree with me!!! Will save you alot of explaining later! Behoove yourself Harold!

J/K, but I am not sure if the chassis is wide enough to drop the emaxx tranny into. I would go with a single motor myself, behind the tranny, with a battery tray/servo mount up front.

Here's a conversion Tony did a little while ago, good place to start for ideas. I think it turned out pretty good. We have two of these trucks sitting on the shelf that nobody's buying, I keep eying (spell check says that's how you spell eye-ing, weird) them up for a build, I have some ideas for it, but no money for those ideas. Oh well, good luck on yours!

Thank's for the link Matt. So will this be the world's "second" MMGT conversion? I have ditched the dual-motor idea. There just isn't enough room (). I have a different plan now- a DDO setup (direct-drive outrunner). That tranny input shaft is suspiciously long, and happens to be 5mm in diameter.

Sounds great! Pics would be a nice addition.

[What's_nitro?]

OK!

[What's_nitro?]

Well, first of all- I'll get pics up tomorrow night...

Second, I took some measurements for a DDO and found that the input shaft is actually too short to mount a good-sized outrunner to. So I found this to replace it with. Then I'll get this motor. I'll be running 5s lipo with a MMM. The motor is spec'd at 1400W handling, and it will be "geared" for about 40 Mph. What do you think?

Get an axi motor, don't waste your time with the cheapo motors... Give sike a pm and ask him what he has, IIRC he has a bunch of motors to move...

[What's_nitro?]

I know Axi motors are the sh!t, but I REALLY don't want to put up the cash for one of them. That Turnigy motor has the specs that I want (not something you find very often while doing a custom build) and it is inexpensive. I have a few of the AeroXP motors already and I am very satisfied with them.

[What's_nitro?]

Here we go. Some pics for ya

So what's the biggest outrunner you guys know of that has a 5mm shaft and about 600kV???

[brushlessboy16]

Turnigy 42-50 600kv

42-60 500kv

42-50 580kv


Take your pick.
