smallest bogie performance
Final update on "the smallest bogie". I put 2 1x4 tiles with 2 studs on the bottom, put on a top plate to make the bogie similar in height to a normal LEGO non-powered bogie, and put the whole thing in a test rig.
It did 51.5cm (4 straight tracks) in 6.2 sec with my current gearing setup (about the maximum an M motor can handle), which means a scale speed of 12km/h. Still pretty slow - but at least it works! Track clearance is only 1 plate less than normal.
Ignore the huge 1x8 technic black brick with holes - my supply of bricks is limited :)
