I think its a combo of the lack of interest in nitro lately plus most have moved on from the tmaxx plus a lot of people use facebook groups (which is a mess) i still have my tmaxx 2.5 but it just sits there
I remember the days of the maxxtraxx forums back in 2001 or so, if you posted something it got tons of responses instantly and by the next day it was 4 or 5 pages back
