TT MTA4 S50 conversion

[j.f.s]

I grew tired of my E-Revo and bought a 6T and converted it and I'm real happy with it. I felt I wanted a MT anyway and spotted a Thunder Tiger MTA4 S50, same as the AE MGT 8.0. Luckily the guy with the S50 was up for a trade so we met up and I switched my ERBE for the S50. Crazy some might say but the ERBE has been shelved since early spring.

Anyway the S50 only had 4 liters through it so it's in pretty good shape. I know that y'all want pics so here goes:









A bit cleaner and with engine, tank, pipe, servos and linkage removed. My youngest son is helping me.











FOC and locked in second gear:

Was going to use a Tekno tray I have laying around but it didn't fit very well so I took the battery tray out of the 6T and placed it on the S50. This is the battery tray from the Mugen MBX6 ECO.


Some candy from Mike and I gotta say it's a piece of art really:




Sweetness!








RCM pinion as well

That's nice indeed, very tidy conversion

[j.f.s]

There are a few things on the to-do list:

convert to 17mm hexes and 8mm stubs
other knuckles
new steering servo
new body
new wheels
RPM arms
sort out shocks & springs

I've read that the upper arm mounts can be a weak spot as well as the shock towers. I guess I'll have to wait and see how it holds up to my abuse :) Fullforce RC has the upper mounts on sale right now but spent waaay to much money on RC's this month already.

Destroyed my 6T's rear diff housing, wing, the 5mm alu brace across the chassis along with the carbon fiber shock tower on a really bad landing=really expensive!

That MGT mount of Mike's looks really nice - and the 1717 looks like the right motor for the job.

Very nice!

Sexy! Mike's mount looks great like all his other work!
Looks like a fun one to drive.

What a nice clean simple conversion. It makes me want a MGT again.

Thanks for the comments guys :)

It'll be a slow build as I'm swamped with work right now so most of my spare time is dedicated to my kids.

Anyway, waiting for a Stampede 4x4 radiobox and I got a set of, according to the seller, 7075 alu 17mm hexes in the mail yesterday. Well, they are 17mm but is it 7075 alu and what grade? Made for the MTA4 and were dirt cheap. They do have one major flaw though and that's that they don't have any support for the hole in the center of the rim.

But for $15 shipped I figured I could try them out until I figure out what knuckles and drive shafts to use.

I hope to get some wrench time tonight when the kids are asleep and more pics will be posted of course.

very cool, I love this conversion

but I'm a really big fan of the MGT

can wait to see a vid

FFRC made great stuff, I had 4 upper mount on mine and they hold just fine all the bash

have you got a link for the 17mm ??

Of course, here's the ebay auction: http://bit.ly/oUzOMC

If they are made for threaded axles, then that is normal, right?

[j.f.s]

Sure, but the stub axles aren't threaded apart for the very tip of it. The hexes slide on the 6mm axle and are held in place by a pin. Like on the 14mm Traxxas or HPI axles. I'll take some pics later on to better illustrate what I mean. :)



I think I may have missed your point a bit there Brian. I just assumed that all adapters/hexes has the support for the rim since Axial ships adapters with their rims and those adapters has extra support for the center of the rim. I could buy HPI's E-savage hexes since the flanged nut HPI provides has the support for the rim built in to them.

Yes, those are the type of nuts I was thinking would be used with these - since you are using the threads on the axle to hold the wheel on - instead of other hex designs that hold the hex on with the axle nut and then use another nut (17mm) to hold the wheel on.

So you could just buy the HPI nuts and use them with these hexes, right?

[j.f.s]

Yes, that's what I'll use until I find a set of beefier axle carriers that wont throw off suspension geometry.

A few parts has found their way to my house:


Notice the Revo knuckle... (more to come on that topic)


This is what the front of the truck looks like right now:
