TT MTA4 S50 conversion

[j.f.s]

Some progress has been made!

I mentioned earlier that I would swap out the knuckles for some beefier stuff. I went with the Revo knuckles and LST XXL drive shafts. Thanks for the guides and sharing your knowledge mistercrash!

This alters the suspension geometry a bit. The CC between the pillow balls on the stock knuckles are 35mm (~1.4") and the E-Revo measures 45mm (~1.8"). I can see some bumpsteer going on but it's not too bad. I'll be trying different shims and see if I can tone it down. I'm using Mugen MBX6-T hexes. I cut off 5mm from the a-arms so the axles will sit in the middle of the drive cup. This mod with the 6T hexes adds 50mm (~2") in total width.





New hole drilled in the stub axle.






Stock vs mod


Liqiud RC was clearing out their old GPM parts so I bought the following:
1 ea. AGM1012AF08 Silver Alum. Fr Gear Box Brace - 1pr
1 ea. AGM1012B08 Silver Alum. Fr/Re Gearbox Tightener
1 ea. AGM1013AR08 Silver Alum. rear gear box brace
1 ea. AGM1014A08 Silver Alum. Fr/Re Chassis Mount
1 ea. AGM1331F Blue Alum. Skid Plate W/Steering Mou
1 ea. AGM1331R Blue Alum. Rear Skid Plate - 1pc
1 ea. AGM1048 Blue Alum. bushing Steering Blue

I know GPM doesn't have the best rep (on par with Integy perhaps) but for $25 shipped I couldn't resist. Figured the would be stronger than the stock plastic parts at least.
