Here is what I know...Marc won the race at REEDY race in USA (actually, Marc, Victor and Atsushi Hara) all using 205G along with 4.0T motor. (you can find the video on youtube)

Then, Marc, Yanni and others...ran the 323stock with 4.0T motor at ETS event (also can be found on youtube). You can compare that 2 track, the ETS is 50% bigger then the Reedy track.
