Mini-T woes

So after getting my Camber tie-rod fixed on Friday, now it seems as though my Mini-T is having servo problems!! Argh - why is this wonderful little RC vehicle so problematic for me??   I wonder to myself whether it was a smart buy, but the little vehicle seems so popular, I don't know if I'd have bought anything else anyways - i mean there is even a location here in Cincinnati where folks race them!   Perhaps everyone just upgrades all the electrical components in them or something?

No clue...anyhow, now the problem is the servo in the Mini-T it works fine for a while, but then it gets "stuck" in a position and won't center itself.  No sounds from the motor or anything.   If I flick the motor, it tends to straighten out.

I'll likely try to get it replaced on warranty, but the Engineer in me wants to open it up and figure out what the heck is wrong with it.  Apparently in order to upgrade to better (non-stock) servo, you have to either replace your ESC and Reciever, *or* hack a server to be a 3-wire servo instead of a 4-wire servo.....so once again, this Mini-T is out of commision....:(
