Turn radii

Hi all, complete newbie here. I am receiving some base boards tomorrow to get me started and it is my plan to run Southern Electric 3rd rail trains, sorry but that`s my thing. I don`t have a great deal of space but I would like to have a continuous run two track circuit as the main feature. My question is, assuming Peco flexi track, what is the absolute minimum radius you can get from this track? Any advice appreciated.

As you want 2 circuits then the outer one will have to be R3 = 505mm that is to the centre line and thus you can add 10mm for the rest of the track and about the same for coach end overhang depending upon how long the coaches are so you need a board = 2 x (505+10+10) = 1050 as you may already found out by now.
