If using the vinyl tracks, I always try to leave either the idler or Drive sproket loose until I am ready to fit the vinyl track - mainly on Tamiya kits which have the poly caps and the wheels are just pressed on. That way you can slip the track over the road wheels and idler/sprocket on the model and then slip the loose idler/sprocket inside the track loop, then fix it to the kit. This way you don't need to twist or flex the track over these components, and little track paint damage can occur. Of course, this doesn't work when the wheel needs to be fixed to the suspension components and the assembly then has to be glued to the kit. The track tension will pull the parts out of alignment if you do this.
Where the wheels are interwoven it can be a bit fiddly too.
Then of course, there are those without the patience to use perfectly good vinyl tracks and just wimp out and go for the indy Fruil or Kasten tracks (Just joking guys don't hurt me!
)
