<{POST_SNAPBACK}>The big problem with Tracksetta is that is does not fit the R1/2/3/4 standard as they are not made by Peco, you will never match the smooth curve of up to R4 from the pre manufactured curves and I would recommend using these on tighter radius.
R4 is 572mm which is 22.5 inches, as a result you do not need any tracksetta less than 24 inches.
Another problem is that as they step up at 3 inch centres then this is 75mm, so you cannot reproduce the 6 foot way (or 50mm centres) using tracksetta alone, you must lay the inside track and then take off the next track by using the Peco red gauge. Even at 24 inches (610mm) the tracks are getting too close so test with coaches to ensure the ends miss the other train on the parallel track.
Next getting the join is difficult, flex does want to straighten out so if you can avoid the join in the middle of a curve do so.
Finally long sweeping curves always look good and at large radiuses you really do not need a tracksetta anyway, so buy the 24, 27, 30 inch ones and try them first. but
the reason i asked is because i'm planing on building a small double track tale chaser layout but i want to use flexy track so i need the equivilant curves of set track but with flexi track, in other words graduated set track
i want the iner curves to be equivilent to R3 and the outer curves equivilent to R4
