I have an MT4G3 still running. I've converted it to truggy for conservation purposes. Also was a member of WonderTiger, RIP.
I still run it some, it's a great platform overall. Shame TT got out of rc's IMO.
Several years back, I did some rehab on it. Needed a new rear diff along with some other odds and ends. The MT-4G5 K-Rock diffs and cvds will work, but you have to change both because TT made the ball ends and shafts thicker on the G5 K Rock..they won't physically fit into the G4 outdrives. Length is unchanged. I picked up as many spares as I could afford at the time from Dollar Hobbyz, they were parting out the K Rocks..
On another note, I have an Arrma k6 exb, it doesn't disappoint IMO. Great rig. I have a bunch of monster truggies, I like to have different makes. Tekno
MT410 stretched on a ET48 chassis, TC Kronos XTR, Mojo exb turned Kraton XL..the Kraton exb has been converted to what I'm calling a Typhon XL, although I don't have a buggy body for it yet. I'm thinking the TC Asuga body should be about perfect.
I'm still looking for MT4-G3 front arms.. at this point, I'm content to let it sit. It's earned a spot on my shelf, one day my grandkids will say "Wow! What's this thing grandpa?" "Does it work?"
