Having made my first version of a train turntable for DUPLO, I received much encouragement to make a version of the RC Train. So I decided to go ahead a make one.
My goal with this version of a train turntable was to make it out of existing LEGO bricks and make it work on a flat surface.
First however I need to find a way to make a circle that would retain its structure. After testing several possibilities I found a version that worked both in real bricks and in LDD.
Using on half of the flexible train tack, I found a dimension that worked and gave a stabile transition from the tracks to the turntable.

with test run on build turntable with roundhouse.
By many requests and approved by LEGO CUUSOO, hire are the LDD files
