Monster GT Conversion With A Center Diff - Page 17 - RC-Monster Forums

The Dude · 01.24.2011, 03:02 AM

2X3S for a good weight repartition and a 1518 , this is my current setup
I sell the 1520, not a huge difference but less wheel speed..

thanks for opinions but i'm think it's too late. 5 min before suicideneil repons to my question i order a 1520 1600 kv in ebay.

what i want was the 1518 but i coulsn't find it anywhere so i don't hava another option.

let's hope that don't stay much bad. maybe later i find the 1518 and replca de 1520.

thanks

about the center diff any one now if the Slipperential™ 1/8 Center Slipper Diff sold but rc-monster is good or there is another one better and more cheap???

There is only one Slipperential. Its RC-Monster's crowning achievement you might say.

suicideneil · 01.24.2011, 08:22 PM

Any other slipperentials you might find are cheap nasty copies- thats what the notice on the rc-monster online shop is about.

OK, I have to come clean....It's embarrasing, but I have never even seen a center diff....It just sounds like, and I understand front and rear diffs, the way to go from my reading...

But in a Emgt conversion, I do not understand WHICH center diff to use. I will like to buy the frenchman's mount, but have no clue if ANY center diff will fit/work. My thought is the most widely available and easy to find and durable is best. I have heard the one from a losi 8ight is good choice.

But then I have to ask, how does braking work...I have read(internet commando aparently) that using the motor itself to brake is tough on the ESC.....I think that is what my Stampedes do?

Thanks,
ST

Any & all electric r/cs use motor braking- the esc essentially shorts out a couple phases an slows the motor down to a halt- how hard you hit the brakes determines how quickly the motor slow down. For most normal r/cs this is fine and isnt detrimental to the motor or esc really; when you have a very large, fast or heavy r/c, then it is perhaps better to use mechanical brakes- such as with 1/5 scale trucks or cars. I think the MGT will be fine with normal motor brakes, the MMM is a tough esc.

Hi
a good news, I've found my spider center diff, so I call my friend today for giving the dimensions
the spider use a 52T spur gear so you need to grind a little your chassis.

more update soon

A bit off topic but, can you tell me the measurement from bearing to bearing? I'm looking to find out if a spyder diff will fit in a project I'm working on. Thanks!!

Nevermind. I found it. Thanks.

Now back on topic.

Sorry, you're so fast

but if someone need I can make a little pic w/ dimensions

Scott_T · 01.27.2011, 10:36 AM

Thought you'd like Frenchman.....Sounds kinda cool, james bond spy like....

So did the spider diff work out???

I finally saw a center in an xtm rail last night. It looks like a way easy setup....

So really this conversion looks fairly easy except for the cost of parts....Freaking motor/esc are not cheap....Way more then my nitro mills...

So worth it though....Still working on funding...

BTW,

Any opinions on the savage flux motor. I think it is a castle and 2200kv....Thinking maybe I can go with a hobbywing or turnigy 150 amp esc and that motor and be under $200....

Then 140 for the Frenchmans mount...

Then the big question on center diff....I see the losi 8ight diff tossed around and it looks like it can be had for $35 or so...

Just trying to get a build plan together in my head....

http://cgi.ebay.com/Losi-Center-Smar...item5196b2720f

and this:

http://cgi.ebay.com/Team-Losi-8ight-...item5ade6268f8

the price of the secons is half of the first but if you see in the pcitures they have some diference.

check it first

Scott_T · 01.27.2011, 11:49 AM

NMS,

I saw that....Is the Smart diff really that much better? I don't get the concept totally....Doh...

And then finally I have to see if it will fit the Frenchmans mount...I saw he is trying a spider diff, so maybe it will not even fit....

I've been following so many Emgt threads anywhere I can find them, that I am getting all confused...LOL

On URC there is folks using Savage tranny's which I did not know was any better then the MGT tranny....
