<\/a><\/p>\nFrom a space perspective, this seemed a promising start. The motor shaft has an 8-tooth gear which drives another 8-tooth gear on the differential shaft. I tried various options for holding the drive shaft firmly in place so the gears wouldn’t cog.<\/p>\n This option is sturdy enough that the motor shaft remains in place. In the car, I used 2L and 3L technic liftarms. A stronger connection can be made using 2L (shown in blue) and 3L\u00a0 (shown in grey) thin lift-arms which have cross-holes for a blue pin-axle. In the above picture, the dark grey 8-tooth gear is on the motor shaft. (with the yellow half-bush). The light-grey 8-tooth gear is on the tan crown gear that meshes with the differential.<\/p>\n Unfortunately, after a few minutes of play, the L-motor is powerful enough to cause damage to an 8-tooth gear: the teeth are forces sideways (in an anti-clockwise direction in the photo below).<\/p>\n Unfortunately there isn’t space to move the L-motor up vertically without seriously changing the structure of the car.
