In the U. S. stairs must be between 4 and 9½ inches high, with average being in the range of 7 - 7¾ inches high. Therefore, with two of the wheels on the ground, the axis of the third wheel should be at least 9½ inches high. Wheels should be large to minimize gaps between and the possibility of stair corner or overhang reaching between to contact and drag on the armature.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4902568138574518299.post-20684117978031903012021-04-16T15:51:42.039+02:002021-04-16T15:51:42.039+02:00Great idea.
