I'm also a big fan of the TA03. I bought my first (TA03F Alfa Romeo) for like 40 bucks, it was red tagged at Hobby People. At the TCS race in Aliso Viejo, I bought a TRF edition for like 50 bucks. I built it and ran it at that race. My friend and I even entered it in the Tamiya Enduro one year. If our speed controller didn't continually overheat, we would have been close to the top 5. Very easy car to drive, I like it.
I saw awhile ago that Car Action did a twin motor TA03. I have a front motor and rear motor TA03, maybe I should make one...
