Some more of the information now floating around on various sites on the TRF201 now added to the TRFracing site on the news page (along with a sneak peak at another new TRF vehicle), and a first stab at hopups/parts added in reviews/tips at
http://www.trfracing.co.uk/page_1266421668280.html (All the new parts are there, plus a guess at which hopups from the 511 are relevant too).
As soon as more information is available or I can confirm the radio race car stuff is all definitely right (I'm sure it is but can't find the source right now), it will be added!
