Picked up my tc6 from Trackside RC in Brisbane yesterday and put most of it together last night.
My thoughts on the new car, check you have diff thrust washers in your kit before you leave the hobby shop, cause there was none in my kit, Jeff from Trackside reported the same with his kit as well, also disappointing was no shock oil and diff greases.

The car went together very well, the new shocks are very easy to build, the piston is now held on by a screw instead of a clip, they were easy to remove any air and get the rebound right.
Diffs are the same except for steel out drives, disappointing to still see that alloy nut which you have to insert into the plastic t-nut.
There's a place to put your transponder in the front bumper now, so overall I can't wait to get some electrics in it and drive, o the tc5 body fits on the posts ok but haven't check with wheels on.
